Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.

Effects of soybean oil emulsion and eicosapentaenoic acid on stress response and immune function after a severely stressful operation. (1/1196)

OBJECTIVE: To investigate the effects of soybean oil emulsion and oral or enteral administration of eicosapentaenoic acid (EPA) on stress response, cytokine production, protein metabolism, and immune function after surgery for esophageal cancer. SUMMARY BACKGROUND DATA: It has been reported that safflower oil, rich in n-6 polyunsaturated fatty acid (n-6 PUFA), affects the survival rate of septic animals and decreases the immune function. It has also been reported that the administration of fish oil, in contrast, reduces these stress responses and stress-induced immunosuppression. In humans, the effects of soybean oil emulsion and the administration of EPA on stress response and immune function after surgery have not been established. METHODS: Patients who underwent esophagectomy with thoracotomy were divided into three groups. Seven patients were fed by total parenteral nutrition (TPN) with soybean oil emulsion, which accounted for 20% of total calories. Seven patients were given oral or enteral administration of 1.8 g/day EPA, in addition to TPN with soybean oil emulsion. Nine patients served as the control group; these patients received fat-free TPN. Serum interleukin-6 (IL-6), C-reactive protein, concanavalin A (con A)- or phytohemagglutinin (PHA)-stimulated lymphocyte proliferation, natural killer cell activity, and stress hormones were measured. RESULTS: The postoperative level of serum IL-6 was significantly higher in the group receiving soybean oil emulsion than in the fat-free group. Oral or enteral supplementation of EPA with soybean oil emulsion significantly reduced the level of serum IL-6 compared with the patients receiving soybean oil emulsion. Con A- or PHA-stimulated lymphocyte proliferation decreased significantly on postoperative day 7 in all groups of patients. The supplementation of EPA with soybean oil emulsion significantly improved the lymphocyte proliferation and natural killer cell activity on postoperative day 21 compared with the group receiving soybean oil emulsion. CONCLUSIONS: Soybean oil emulsion amplifies, and the supplementation of EPA reduces, the stress response and stress-induced immunosuppression.  (+info)

Effective method for activity assay of lipase from Chromobacterium viscosum. (2/1196)

A method was devised for activity assay of the lipase [triacylglycerol acyl-hydrolase, EC 3.1.1.3] excreted from Chromobacterium viscosum into the culture medium; olive oil emulsified with the aid of Adekatol 45-S-8 (a non-ionic detergent, the ethoxylate of linear sec-alcohols having chain lengths of 10--16 carbon atoms) was used as the substrate. This method was specifically effective for Chromobacterium lipase acitvity assay, and was approximately twice as sensitive as the conventional method, in which polyvinyl alcohol is used for the emulsification of the substrate.  (+info)

Leucine metabolism in preterm infants receiving parenteral nutrition with medium-chain compared with long-chain triacylglycerol emulsions. (3/1196)

BACKGROUND: Although medium-chain triacylglycerols (MCTs) may be utilized more efficiently than long-chain triacylglycerols (LCTs), their effect on protein metabolism remains controversial. OBJECTIVE: The aim of the study was to compare the effects of mixed MCT-LCT and pure LCT emulsions on leucine metabolism in preterm infants. DESIGN: Fourteen preterm [gestational age: 30+/-1 wk; birth weight: 1409+/-78 g (x +/- SE)] neonates were randomly assigned to receive, from the first day of life, either a 50:50 MCT-LCT (mixed MCT group; n = 7) or an LCT (LCT group; n = 7) lipid emulsion as part of an isonitrogenous, isoenergetic total parenteral nutrition program. On the fourth day, infants received intravenous feeding providing 3 g lipid, 15 g glucose, and 3 g amino acids kg(-1) x d(-1) and underwent 1) indirect calorimetry and 2) a primed, 2-h infusion of H13CO3Na to assess the recovery of 13C in breath, immediately followed by 3) a 3-h infusion of L-[1-13C]leucine. RESULTS: The respiratory quotient tended to be slightly but not significantly higher in the mixed MCT than in the LCT group (0.96+/-0.06 compared with 0.93+/-0.03). We did not detect a significant difference between the mixed MCT and LCT groups with regard to release of leucine from protein breakdown (B; 309+/-40 compared with 257+/-46 micromol x kg(-1) x h(-1)) and nonoxidative leucine disposal (NOLD; 296+/-36 compared with 285+/-49 micromol x kg(-1) x h(-1)). In contrast, leucine oxidation was greater in the mixed MCT than in the LCT group (113+/-10 compared with 67+/-10 micromol x kg(-1) x h(-1); P = 0.007). Net leucine balance (NOLD - B) was less positive in the mixed MCT than in the LCT group (-14+/-9 compared with 28+/-10 micromol x kg(-1) x h(-1); P = 0.011). CONCLUSION: Mixed MCTs may not be as effective as LCT-containing emulsions in promoting protein accretion in parenterally fed preterm neonates.  (+info)

The adsorption-induced secondary structure of beta-casein and of distinct parts of its sequence in relation to foam and emulsion properties. (4/1196)

Changes in the secondary structure upon adsorption of beta-casein (betaCN) and of distinct parts of its sequence were investigated by far-ultraviolet circular dichroism in order to find suggested relationships with foam and emulsion-forming and -stabilising properties of the same protein/peptides. A teflon/water interface was used as a model system for foam and emulsion interfaces. The maximum surface loads of beta-casein and its derived peptides were investigated. The main secondary structure element of all samples in solution was the unordered random coil, but upon adsorption ordered structure, especially alpha-helix, was induced. At lower pH more ordered structure was induced, just as at lower ionic strength. Apparently, both hydrophobic and hydrophilic groups influence the change of secondary structure induced at a hydrophobic interface. The results suggest that the hydrophobic C-terminal half of betaCN accounted for the high maximum surface load on teflon, while the N-terminal half of betaCN seemed to be responsible for the secondary structure induction upon adsorption. A relation between the maximum surface load and the foam-stabilising properties was found, but an influence of the secondary structure properties on the foam and emulsion-forming and -stabilising properties was not observed.  (+info)

Oxidized low-density lipoprotein as a delivery system for photosensitizers: implications for photodynamic therapy of atherosclerosis. (5/1196)

Photodynamic therapy is a promising new strategy in the treatment of cardiovascular diseases. Photodynamic therapy for vascular diseases may be improved by the specific delivery of photosensitizers to the atherosclerotic lesion. In this study, we studied whether oxidatively modified low-density lipoprotein (OxLDL) could be used as a specific carrier for photosensitizers, thereby using the scavenger receptor expressed on macrophages as a target. The photosensitizer aluminum phthalocyanine chloride (AlPc) was incorporated into OxLDL, and its photodynamic effects were studied. Macrophages (RAW 264.7) were incubated with various concentrations of OxLDL-AlPc for different periods. After illumination of the cells with red light, cytotoxicity was observed that was dependent on the time of illumination and incubation. Macrophages incubated with OxLDL-AlPc that were not illuminated revealed no cytotoxicity. The uptake of the OxLDL-AlPc complexes was mediated by scavenger receptors expressed on macrophages. In the presence of the polyanion polyinosinic acid, a specific ligand for scavenger receptors, no cytotoxicity could be observed. Serum incubations of the OxLDL-AlPc complexes revealed that these complexes stay intact after incubation. No redistribution of AlPc to other plasma (lipo-) proteins could be detected, and 80-90% of the AlPc remained associated with the OxLDL particle. These results indicate that OxLDL may function as a specific delivery system for photosensitizers to the scavenger receptors expressed on the macrophages in the atherosclerotic lesion, increasing the beneficial effects of photodynamic therapy for cardiovascular diseases.  (+info)

Developmental regulation of expression of the D3 dopamine receptor in rat nucleus accumbens and islands of Calleja. (6/1196)

The dopamine D3 receptor (D3R) belongs to the D2 subfamily and is expressed in the rat brain in targets of the mesolimbic dopaminergic system. Little is known about its normal development and control by dopaminergic innervation. We studied developmental expression of D3R in the rat nucleus accumbens (NAC) and islands of Calleja (ISC). At postnatal day (P) 7, D3 binding sites and mRNA were low in both areas. By P14, D3R and mRNA concentrations were close to adult levels in the ISC, whereas, in the NAC, binding increased until 3 months after birth. Cellular concentrations of D3 mRNA in the ISC increased with age in conjunction with a decrease in the number of D3 positive cells. In the NAC, the number of positive cells increased, whereas cellular levels of expression remained unchanged. Neonatal 6-hydroxydopamine lesion caused age-dependent changes in D3R expression. D3 binding sites did not change at P7 or P14, but there was a reduction in the number of D3 mRNA positive neurons accompanied by an increase in cellular levels of D3 mRNA at P14, suggesting that changes occurred in a subset of neurons. Up-regulation of D3 binding sites in NAC and ISC occurred 1 month after the lesion (P35) concomitant with a decrease in cellular levels of D3 mRNA and the number of D3 mRNA positive cells. At 3 months (P90) after the lesion, an increase in D3 mRNA occurred with no change in D3 binding sites. D3R shows region-specific dynamics in receptor/mRNA expression during development and is sensitive to loss of dopamine in early postnatal development.  (+info)

Doppler sonographic enhancement of hepatic hemangiomas and hepatocellular carcinomas after perflenapent emulsion: preliminary study. (7/1196)

Ultrasonographic microbubble contrast agents improve Doppler signals by increasing blood backscatter. We retrospectively reviewed our experience with perflenapent (EchoGen), an emulsion of liquid dodecafluoropentane, in the evaluation of 13 patients with focal hepatic lesions (10 hemangiomas and six hepatocellular carcinomas). Perflenapent improved the detection of color Doppler flow signals within the lesions. The hemangiomas showed peripheral nonpulsatile signals and the hepatocellular carcinomas showed more diffuse enhancement with both arterial and venous type signals. This preliminary study suggests that perflenapent administration may aid in the sonographic differentiation of these focal lesions.  (+info)

Hydrolysis of emulsified mixtures of triacylglycerols by pancreatic lipase. (8/1196)

Hydrolysis of the emulsified mixture of short-chain triacylglycerols by porcine pancreatic lipase in the presence of procolipase and micellar sodium taurodeoxycholate has been studied. Increase in the content of tributyrin and trioctanoin in the mixture with triacetin had highly cooperative effects on the formation of the interfacial lipase procolipase complex. Abrupt enhancement of the complex stability was observed in the presence of 0.4-0.6 mol mol-1 of tributyrin or 0.58 mol mol-1 of trioctanoin in the substrate phase. The affinity of lipase towards interfacially bound procolipase for the trioctanoin containing 0.07-0.42 mol mol-1 of triacetin was approximately three times higher than that for pure trioctanoin. The cooperative processes involved in complex formation did not contribute to the affinity of the interfacial lipase/(pro)colipase complex towards substrate molecules and its catalytic activity.  (+info)

Self-emulsifying drug delivery systems (SEDDSs) originated as an oral lipid-based drug delivery system with the sole purpose of improving delivery of highly lipophilic drugs. However, the revolutionary drug delivery possibilities presented by these uniquely simplified systems in terms of muco-adhesiveness and zeta-potential changing capacity lead the way forward to ground-breaking research. Contrarily, SEDDSs destined for topical/transdermal drug delivery have received limited attention. Therefore, this review is focused at utilising principles, established during development of oral SEDDSs, and tailoring them to fit evaluation strategies for an optimised topical/transdermal drug delivery vehicle. This includes a detailed discussion of how the authentic pseudo-ternary phase diagram is employed to predict phase behaviour to find the self-emulsification region most suitable for formulating topical/transdermal SEDDSs. Additionally, special attention is given to the manner of characterising oral SEDDSs
Emulsions are colloidal dispersions formed by two immiscible liquids.1 The dispersed phase of an emulsion appears as droplets of a certain size distribution immersed in the continuous phase of another liquid. The properties of emulsions-appearance, rheology, and physical stability-may follow those of the constituents or show completely new material behavior based on the spatial distribution and interactions of polymers, particles, and droplets.2 The most abundantly used emulsions are those consisting of oil and an aqueous phase, that is, oil-in-water (o/w) or water-in-oil (w/o) emulsions.1 They are used in the chemical industry, pharmaceuticals, cosmetics, and food, the latter of which can be viewed as a complex form of soft matter.2 Food emulsions include creams, spreads, dressings, and beverages. Thus, emulsions are versatile systems with wide industrial applications and multiple functions. Owing to the immiscible nature of the dispersed and the continuous phases, emulsions are ...
There is provided a water-in-oil (w/o) micro emulsion which readily converts to an oil-in-water (o/w) emulsion by the addition of aqueous fluid to the w/o microemulsion, whereby an water-soluble biologically-active material in the aqueous phase is released for absorption by the body. The w/o microemulsion contains a preferred high purity short chain monoglyceride surfactant. The w/o microemulsion is particularly useful for storing proteins and the like for ling periods of time at room temperature and above until they are ready for use, at which time the addition of aqueous fluid converts the microemulsion to an o/w emulsion and release the protein.
Chitosan (CS) microparticles with and without cross-linking were prepared by a water-in-oil emulsion solvent diffusion method without any surfactants. Aqueous CS solution and ethyl ace- tate were used as water and oil phases, respectively. Genipin was used as a cross-linker. Influ- ences of genipin ratios and cross-linking times on CS microparticle characteristics were investigated. Non-cross-linked and cross-linked CS microparticles were spherical in shape and rough in surface. Microparticle matrices showed porous structures. Surface roughness, mean par- ticle sizes and bulk density of CS microparticles increased and their dissolutions in acetic acid solution decreased when genipin ratio and cross- linking time increased.
Purpose: Dry eye disease is a complex, multifactorial pathology characterized by corneal epithelium lesions and inflammation. The severity of these assaults is often correlated to the severity of the disease. The aim of the present study was to evaluate the efficacy of a cationic emulsion of cyclosporine (CsA) in a mouse model that mimics severe dry eye.. Methods: Eight to 12-week-old female C57BL6 mice with tail patches of scopolamine (replaced every other days) were housed in controlled environment chambers (CEC) to induce dry eye. At day three, following dry eye confirmation by corneal fluorescein staining (CFS, score 0-15) and phenol red thread (PRT) lacrimation test, the mice (n=10/gp) were either treated 3 times a day in both eyes with: drug-free cationic emulsion, a 0.1% CsA-loaded cationic emulsion, and 1% methylprednisolone (positive control), or left untreated. Aqueous tear production, CFS score, Goblet cell density in the conjunctiva and CD11b+ count in flat mounted cornea were ...

Purpose: The aim of this project was to develop a colloidal dosage form for the oral delivery of rifampicin and isoniazid in combination with the aid of artificial neural network (ANN) data modeling.. Methods: Data from the 20 pseudoternary phase triangles containing miglyol 812 as the oil component and a mixture of surfactants or a surfactant/cosurfactant blend were used to train, test, and validate the ANN model. The weight ratios of individual components were correlated with the observed phase behavior using radial basis function (RBF) network architecture. The criterion for judging the best model was the percentage success of the model prediction.. Results: The best model successfully predicted the microemulsion region as well as the coarse emulsion region but failed to predict the multiphase liquid crystalline phase for cosurfactant-free systems indicating the difference in microemulsion behavior on dilution with water.. Conclusions: A novel microemulsion formulation capable of delivering ...
295879012 - EP 0973484 A1 20000126 - OIL-IN-WATER EMULSIONS FOR RECONSTITUTING LAMELLARITY OF THE LIPID STRUCTURE OF DAMAGED SKIN - [origin: DE19713793A1] Oil-in-water emulsions with lamellar, liquid crystal phases contain a cosmetic oil or fat component, a hydrophile emulsifier and a lipophile co-emulsifier which is a lipid of the formula R 1 -O-R 2 , in which R 1 stands for a primary, linear alkyl group, alkenyl group or acyl group with 20 to 30 C-atoms and R 2 stands for hydrogen or a hydroxyalkyl group, a hydroxyalkoxyalkyl group or a polyhydroxyalkyl group. Behenyl alcohol is preferably used as a lipophile co-emulsifier. The emulsions enhance the lamellarity and the degree of order of the epidermal lipid structures of the skin.[origin: DE19713793A1] Oil-in-water emulsions with lamellar, liquid crystal phases contain a cosmetic oil or fat component, a hydrophile emulsifier and a lipophile co-emulsifier which is a lipid of the formula R 1 -O-R 2 , in which R 1 stands for a primary, linear alkyl
Clopidogrel, an inhibitor of platelet aggregation, selectively inhibits the binding of adenosine diphosphate (ADP) to its platelet receptor and the subsequent ADP-mediated activation of the glycoprotein GPIIb/IIIa complex, thereby inhibiting platelet aggregation. Oral bioavailability of clopidogrel is very low (less than 50%), due to its poor water solubility. The aim of this investigation was to design and develop a microemulsion formulation of clopidogrel for enhancing its solubility, and hence its oral bioavailability. For this purpose, initially, solubility of clopidogrel was determined in various vehicles. Next, pseudo-ternary phase diagrams were constructed to identify the microemulsion existing zone. Solubility study was also performed for optimization of formulation. The optimized microemulsion formulation was characterized for its transparency, droplet size, zeta potential, viscosity, conductivity, % assay, and phase separation study. Particle size and zeta potential of the optimized
The potential of dihydroxyacetone phosphate (DHAP)-dependent aldolases to catalyze stereoselective aldol additions is, in many instances, limited by the solubility of the acceptor aldehyde in aqueous/co-solvent mixtures. Herein, we demonstrate the efficiency of emulsion systems as reaction media for the class I fructose-1,6-bisphosphate aldolase (RAMA) and class II recombinant rhamnulose-1-phosphate aldolase from E. coli (RhuA)-catalyzed aldol addition between DHAP and N-benzyloxycarbonyl (N-Cbz) aminoaldehydes. The use of emulsions improved the RAMA-catalyzed aldol conversions by three to tenfold relative to those in conventional DMF/water mixtures. RhuA was more reactive than RAMA towards the N-Cbz aminoaldehydes regardless of the reaction medium. With (S)- or (R)-Cbz-alaninal, RAMA exhibited preference for the R enantiomer, while RhuA had no enantiomeric discrimination. The linear N-Cbz aminopolyols thus obtained were submitted to catalytic intramolecular reductive amination to afford the ...
In a previous work, we showed the extension of the microemulsion area towards highly or fully water dilutable systems by adding a short chain alc. as cosolvent, like ethanol, to the system water/sodium oleate/citronellol/limonene. It was possible to convert an anti-percolative system to a percolative one by making the interfacial film more flexible. The question arises if this is a general concept. For this reason, we investigated pseudo-ternary systems water/surfactant/cosurfactant/ethanol/oil with different cosurfactants (1-pentanol, 1-heptanol, dodecanol, Guerbet alcs.) and fatty acid Me ester-rapeseed biodiesel as oil phase. Sodium oleate was used as surfactant. Ethanol was added as cosolvent to enhance the film flexibility and so to increase the microemulsion area. With increasing hydrophobicity of the cosurfactants and the oil and without further addn. of ethanol, only very restricted single phase areas were obtained. However, with a certain amt. of ethanol, sodium oleate, and 1-heptanol a ...
The fabrication of soft nanocomposite clay armored polymer latexes is described. Laponite clay XLS is used as stabilizer in the Pickering emulsion polymerization of a variety of monomer mixtures, that is, methyl methacrylate and n-butyl acrylate, styrene and n-butyl acrylate, and styrene and 2-ethylhexyl acrylate. Overall solids contents of the hybrid latexes in complete absence of coagulation of up to 24 wt % are reported under batch conditions. Key mechanistic aspects of the Pickering emulsion polymerization process are discussed. The use of monomers that have high water solubility and are prone to hydrolyze under basic conditions, for example methyl methacrylate, should be restricted. The use of small amounts of methacrylic acid as auxiliary monomer promotes clay adhesion to the surface of the particles in the Pickering emulsion (co)polymerization of hydrophobic monomers. Detailed kinetic studies at both 60 and 80 °C of the Pickering emulsion copolymerization of styrene and n-butyl ...

Introducing water into spray combustion systems, by either water-in-oil emulsification or supplementary water injection, is one of the major techniques for combustion improvement and NOx reduction. Plentiful researches are available on combustion of water-in-oil emulsion fuel drops. The emulsified liquid is a heterogeneous mixture of immiscible liquids. One component forms the continuous phase and the other component forms the discrete phase. The discrete phase consists of globules of the one fluid that are suspended in the continuous phase fluid. Water-in-oil emulsions are commonly considered for combustion applications because emulsions can result in micro-explosion, thereby reducing the average drop diameter to enhance liquid vaporization, and suppressing the formation of soot and NOx. However, the water addition generally does not exceed about 20% for smooth engine operations[!, 21. The combustion characteristics and micro-explosion of emulsion drop were studied by many researchers. The ...
Emulsion polymerizations of vinyl acetate (VAc) were performed by fully or partially replacing poly(vinyl alcohol) (PVA) with renewable materials as protective colloids or by adding renewable materials, as additives or fillers, to the emulsions during or after polymerization. The purpose of the study was to increase the amount of renewable materials in the emulsion.. A total of 19 emulsions were synthesized. Different recipes were used for the synthesis. The following renewable materials were studied; hydroxyethyl cellulose (HEC) with different molecular weights, starch and proteins. HEC and starch were used as protective colloids. Proteins were used as additives or fillers. Cross-linking agent A and Cross-linking agent B were used as cross-linking agents. A total of 26 formulations were pressed, either cold or hot.. The synthesized emulsions were evaluated with respect to pH, solids content, viscosity, minimum film formation temperature (MFFT), glass transition temperature (Tg), particle size ...
The application of crossflow ceramic microfiltration (CFCMF) to the removal of emulsified oil from a simple analogue of raw produced water (PW) arising from oil exploration has been studied. Outcomes relate to surfactant-stabilised oil-in-water (o/w) emulsions both as a discrete emulsion and in combination with a colloidal suspension of particulate solids (bentonite). The impact on both fouling during the filtration cycle and residual fouling of the ZrO2-TiO2 membrane, following aggressive caustic-acid chemical cleaning applied between six sequential 30-min filtration runs, was investigated. Results showed the addition of suspended solids to the o/w emulsion to be extremely deleterious to sustaining both the permeability and selectivity of the membrane. The addition of 1500 mg·L−1 of bentonite to a 10 vol.% emulsion resulted in a permeability decrease of 3.5-5 times over that recorded for the emulsion, and 8-36 times lower than that of the bentonite suspension. Oil passage through the ...
Abstract PURPOSE. The generation of reactive oxygen species and lipid peroxidation are associated with tissue injury following ischemic insult; therefore, the use of antioxidants appears rational in the improvement of kidney diseases therapy. The aim of the present study was to assess the effect of aqueous saffron extract (Crocus sativus L.) and its active constituent, crocin, on oxidative stress following renal ischemia-reperfusion injury (IRI) in rats. METHODS. The cellular redox status (thiobarbituric acid reactive species (TBARS) and total thiol levels) and antioxidant power (using ferric reducing/antioxidant power test) were assessed in control and ischemic groups. The left kidney was exposed to warm ischemia for 60 min followed by reperfusion for 90 min. The macerated aqueous extract of saffron (with doses of 5, 20 and 80 mg/kg, i.p.) and crocin (with doses of 50, 200 and 400 mg/kg, i.p.) were administrated prior to induction of ischemia. Normal saline (10 ml/kg, i.p.) was injected to ...
Mayonnaise, besides ketchup or mustard, is one of the most popular sauces in the world. It is prepared by stirring oil in egg yolk. Depending on the formulation, various amounts of egg yolk as well as salt, pepper, vinegar or lemon juice are added. From a chemical point of view, mayonnaise is an oil-in-water (O/W) emulsion, containing at least 65 % of oil from plant origin. To obtain a stable emulsion, the surface tension needs to be lowered, which is achieved by lecithin in the egg yolk. Due to its hydrophilic-lipophilic balance (HLB) value, lecithin favors water-in-oil (W/O) emulsions. With such high oil content, one would expect that after mixing the ingredients, a W/O emulsion is created. In fact, the oil is added drop by drop, preventing phase reversal, and in the end, an O/W emulsion is created, which gives mayonnaise its creaminess and consistency. Consumers like to enjoy a creamy, particle-free and smooth mouth feel, but at the same time the product should be inexpensive. Healthy ...
Emulsions contain both a dispersed and a continuous phase, with the boundary between the phases called the interface[4]. Emulsions tend to have a cloudy appearance because the many phase interfaces scatter light as it passes through the emulsion. Emulsions appear white when all light is scattered equally. If the emulsion is dilute enough, higher-frequency (low-wavelength) light will be scattered more, and the emulsion will appear bluer - this is called the Tyndall effect.[citation needed]If the emulsion is concentrated enough, the color will be distorted toward comparatively longer wavelengths, and will appear more yellow. This phenomenon is easily observable when comparing skimmed milk, which contains little fat, to cream, which contains a much higher concentration of milk fat. One example would be a mixture of water and oil.[citation needed] Two special classes of emulsions - microemulsions and nanoemulsions, with droplet sizes below 100 nm - appear translucent.[5] This property is due to ...
0027] According to the invention, the emulsion of phase A and phase B can be of the oil-in-water emulsion type or of the water-in-oil emulsion (W/O) type. Accordingly, the substance to be encapsulated can be a hydrophilic or a hydrophobic substance. In the case of the embodiment of a hydrophilic substance to be encapsulated, a water-in-oil emulsion is produced. In the case of the embodiment of a hydrophobic substance to be encapsulated, an oil-in-water emulsion (O/W) is produced. In one or more embodiments, the method according to the invention is used for encapsulating hydrophobic substances. The emulsion type can be adjusted via the selection of the interface-active substance. Furthermore, the emulsion type can be adjusted via the quantitative ratio of continuous phase to disperse phase ...
An emulsion is a metastable suspension of droplets of one fluid within another fluid, with the two fluids being immiscible. Emulsion droplets are stabilized against coalescence upon contact by a range of surfactants; typically, surfactants are ionic, imparting stability due to electrostatic repulsions at the droplet interfaces. For low volume fractions, a Brownian emulsion is liquid-like; as the volume fraction of droplets increases, the viscosity of the emulsion may diverge (at the colloidal glass transition, volume fraction ~ 58%), similar to a hard-sphere suspension. However, while a disordered hard-sphere suspension can only be packed up to a maximum volume fraction of 64% (random close packing), a disordered emulsion can be packed past random close packing, due to the deformability of the emulsion droplets. When the droplets first begin to touch (at random close packing), the system jams: it becomes solid-like, and develops an elastic modulus. A good deal of work in the past decade has ...

The droplet sizes and size distributions of DOTAP emulsions were dependent on oils which had different interfacial tensions. The droplet sizes followed the order of squalene emulsionsoybean oil emulsion,linseed oil emulsion,DOTAP liposome. The squalene emulsion showed the least cytotoxicity with or without serum. For in vivo gene transfer, the squalene emulsion also had the most potent transfection activity in the ...
An emulsion is a mixture of two liquids that are typically immiscible (dont blend) that forms a two phase system. One of the two liquids is dispersed in the mixture, forming the dispersed phase. The other liquid contains the dispersion and is known as the continuous phase. An example of two immiscible liquids would be water and oil. In general an emulsion will be unstable since the dispersed phase will try to decrease its surface tension by grouping with other dispersed droplets until the liquids separate again. However, a stable emulsion can be formed by the addition of emulsifiers, such as surfactants that distribute themselves around the interface between the two liquids, creating a stable system. Emulsions are generally regarded as a special class of colloids where both the continuous and dispersed mediums are liquid. However, this distinction is not rigid with some people such as Witten specifying the term colloid only for a mixture of solids and liquids. ...
Benefits of emulsions. An emulsion refers to a mixture of at least two liquids that normally do not mix well together. Â Some people also refer to the mixture as a colloid but strictly speaking, when the initial dispersed phase and the next continuous phase both result into a liquid form, the object involved is called an emulsion. Â Making emulsions has a variety of applications in many industries and can provide the following benefits:. 1. Wide use in the food industry. Vinaigrette, mayonnaise, and milk are just few of the many food items that are actually created by means of emulsion. Â In the case of vinaigrette, vegetable oil is mixed with vinegar. Â Mayonnaise meanwhile contains oil and water while milk has milk fat and water. Â All these emulsion liquids are made stable through a substance called an emulsifier. Emulsifiers act as kinetic stabilizers of the liquid mixture involved.. 2. Medicinal use. Various beauty products and topical creams are also created from emulsions making ...
Important insights into the role of interfacial composition and structure in controlling the digestion of oil-water emulsions have been gained in the last decade. The driving interest relies on: i) the necessity of controlling the digestion of lipids to decrease or delay fat intake to address the obesity crisis existing worldwide and ii) assuring the bioaccessibility of bioactive emulsified lipids or hydrophobic bioactive compounds. This article mainly reviews the relationship between the composition and structure of protein and polysaccharides stabilized emulsions and their susceptibility to in vitro lipolysis. The analysis concentrates on emulsions where (1) proteins or (2) polysaccharides are used as single emulsifiers, (3) emulsions stabilized by protein-polysaccharide conjugates, (4) protein-polysaccharide multilayer emulsions where the primary emulsion is formed by a protein, (5) protein-polysaccharide emulsions where proteins are the main emulsifiers and the polysaccharides perform as ...
Reduction of sodium chloride in food products has been reported to lower consumers acceptance. In this research, the physical characteristics and sensory property of an oil in water emulsion containing sodium chloride, as well as its application in corn soup were studied. The main objectives of this this research were to evaluate salt reduction that could be achieved through emulsion and to obtain a stable emulsion with most applicable viscosity for corn soup. In research stage I, three different oil concentrations (23, 28, and 33%) with constant salt and stabilizers concentration were applied into the emulsions. The result showed that emulsion with 33% oil was significantly more viscous than the others, whilst emulsion with 23% oil was found to be less salty than the others (α=0.05). Emulsion with 28% oil content was chosen for research stage II due to appropriate saltiness and viscosity. In research stage II, different types and concentrations of thickening agent (1 and 2% tapioca; 0.1 and ...

Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography, it consists of silver halide crystals dispersed in gelatin. The emulsion is usually coated onto a substrate of glass, films (of cellulose nitrate, cellulose acetate or polyester), paper, or fabric. Photographic emulsion is not a true emulsion, but a suspension of solid particles (silver halide) in a fluid (gelatin in solution). However, the word emulsion is customarily used in a photographic context. Gelatin or gum arabic layers sensitized with dichromate used in the dichromated colloid processes carbon and gum bichromate are sometimes called emulsions. Some processes do not have emulsions, such as platinum, cyanotype, salted paper, or kallitype. Photographic emulsion is a fine suspension of insoluble light-sensitive crystals in a colloid sol, usually consisting of gelatin. The light-sensitive component is one or a mixture of silver halides: silver bromide, chloride ...
Latex emulsions are disclosed which can be used in the formation of coating compositions that are not water sensitive, have good blush resistance and retortability. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Coating compositions of the invention may be prepared by polymerizing at least one ethylenically unsaturated monomer component, a stabilizer comprising a strong acid and an initiator in a carrier to form an emulsion, polymerizing the emulsion with at least one different ethylenically unsaturated monomer component to prepare the composite latex emulsion, and reacting the composite latex emulsion with a neutralizer to form the coating composition. Methods of coating substrates with the coating compositions, and substrates coated with the coating compositions are also disclosed.
When it comes to flavoring, professional bakers almost exclusively use emulsions over alcohol-based extracts. The flavors are more robust and wont bake-out when exposed to heat. Use bakery emulsions just like you would a baking extract. 1 teaspoon bakery emulsion = 1 teaspoon extract What is a baking emulsion? A baking emulsion is a flavor suspended in a base containing mostly water. In contrast, baking extracts are flavors suspended in a base containing mostly alcohol. Our Bakery Emulsions are not compromised by the flavor of alcohol and dont bake-out when exposed to heat like an extract flavor. Use anywhere you would a baking extract - in cakes, cookies, cheesecakes, frostings and more.
The present invention generally provides a method for producing an exfoliated nanocomposite. The method involves charging to water, as the continuous phase, monomers, polymerizable surfactant, and water-soluble initiator. The monomers are allowed to polymerize under agitation to form an emulsion of polymers, and the polymerizable surfactant is bound to the polymers so formed, with an ionic end of the polymerizable surfactant extending from the polymers to provide surface charges. Thereafter, a suspension of nanofillers in water is charged to the emulsion. The nanofillers are oppositely charged from the ionic end of the polymerizable surfactant such that they electrostatically bind to the polymers within the emulsion. The water is subsequently decanted to produce a nanocomposite with an exfoliated structure.
The initial objective of this work was to evaluate and introduce fabrication techniques based on W/0/W double emulsion and 0/W single emulsion systems with solvent evaporation for the incorporation of a surrogate macromolecule (BSA) into microspheres and microcapsules fabricated using P(HB-HV}, PEA and their blends. Biodegradation, expressed as changes in the gross and ultrastructural morphology of BSA loaded microparticulates with time was monitored using SEM concomitant with BSA release. Spherical microparticulates were successfully fabricated using both the W/0/W and 0/W emulsion systems. Both microspheres and microcapsules released BSA over a period of 24 to 26 days. BSA release from P(HB-HV)20% PCL 11 microcapsules increased steadily with time, while BSA release from all other microparticulates was characterised by an initial lag phase followed by exponential release lasting 6-11 days. Microcapsules were found to biodegrade more rapidly than microspheres fabricated from the same polymer. ...
This invention is directed to a microemulsion system comprising a first phase including a low-polarity fluid material which is a gas at standard temperature and pressure, and which has a cloud-point density. It also includes a second phase including a polar fluid, typically water, a monomer, preferably a monomer soluble in the polar fluid, and a microemulsion promoter for facilitating the formation of micelles including the monomer in the system. In the subject process, micelles including the monomer are formed in the first phase. A polymerization initiator is introduced into the micelles in the microemulsion system. The monomer is then polymerized in the micelles, preferably in the core of the micelle, to produce a polymeric material having a relatively high molecular weight.
The first algorithm for Emulsion Stability Simulations (ESS) was presented at the V Conferencia Iberoamericana sobre Equilibrio de Fases y Diseño de Procesos [Luis, J.; García-Sucre, M.; Urbina-Villalba, G. Brownian Dynamics Simulation of Emulsion Stability In: Equifase 99. Libro de Actas, 1st Ed., Tojo J., Arce, A., Eds.; Solucions: Vigo, Spain, 1999; Volume 2, pp. 364-369]. The former version of the program consisted on a minor modification of the Brownian Dynamics algorithm to account for the coalescence of drops. The present version of the program contains elaborate routines for time-dependent surfactant adsorption, average diffusion constants, and Ostwald ripening.
A new rotating membrane emulsification system using a stainless steel membrane with 100 μm laser drilled pores was used to produce oil/water emulsions consisting of 2 wt% Tween 20 as emulsifier, paraffin wax as dispersed oil phase and 0.01-0.25 wt% Carbomer (Carbopol ETD 2050) as stabilizer. The membrane tube, 1 cm in diameter, was rotated inside a stationary glass cylinder, diameter of 3 cm, at a constant speed in the range 50-1500 rpm. The oil phase was introduced inside the membrane tube and permeated through the porous wall moving radially into the continuous phase in the form of individual droplets. Increasing the membrane rotational speed increased the wall shear stress which resulted in a smaller average droplet diameter being produced. For a constant rotational speed, the average droplet diameter increased as the stabilizer content in the continuous phase was lowered. The optimal conditions for producing uniform emulsion droplets were a Carbomer content of 0.1-0.25 wt% and a membrane ...

The use of conventional emulsions for tack coats can cause problems as they frequently stick to the tyres of construction vehicles. Consequently, the bond between the asphalt layers is inadequate. Recently, new types of emulsions have been developed from very lowpenetration bitumen that contain no flux. They are known as heat-adhesive emulsions and they are resistant to construction vehicles. However, the adhesive ability of these new emulsions has not previously been studied closely, particularly at low temperatures. The purpose of this study is to analyse the effect of different heat-adhesive emulsions and to verify their performance in service in comparison with the response of a conventional emulsion. For this reason a new shear test-the LCB test-has been developed. This test is carried out at different temperatures, both on laboratory specimens and on cores extracted from recently constructed pavements, where the same emulsions and dosages have been used. It is the modified heat-adhesive ...
