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.
Unctuous combustible substances that are liquid or easily liquefiable on warming, and are soluble in ether but insoluble in water. Such substances, depending on their origin, are classified as animal, mineral, or vegetable oils. Depending on their behavior on heating, they are volatile or fixed. (Dorland, 28th ed)
Any of several processes in which undesirable impurities in water are removed or neutralized; for example, chlorination, filtration, primary treatment, ion exchange, and distillation. It includes treatment of WASTE WATER to provide potable and hygienic water in a controlled or closed environment as well as provision of public drinking water supplies.
Water Pollutants, Chemical
A complex mixture of PHOSPHOLIPIDS; GLYCOLIPIDS; and TRIGLYCERIDES; with substantial amounts of PHOSPHATIDYLCHOLINES; PHOSPHATIDYLETHANOLAMINES; and PHOSPHATIDYLINOSITOLS, which are sometimes loosely termed as 1,2-diacyl-3-phosphocholines. Lecithin is a component of the CELL MEMBRANE and commercially extracted from SOYBEANS and EGG YOLK. The emulsifying and surfactant properties are useful in FOOD ADDITIVES and for forming organogels (GELS).
Parenteral Nutrition, Total
The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of TPN solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins.
Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.

- Many heretofore known invert emulsions have been sensitive to at least one or more contaminants and have exhibited a tendency to flip to the oil-in-water type of emulsion or to degrade in desirable properties, such as fluid loss or viscosity. (google.co.uk)
- 5) Rheological properties: The invert emulsion should have viscosity and gel strength characteristics suitable for its intended use and controllable by addition of oil or water or by simple chemical treatment. (google.co.uk)
- Measurements of water content and viscosity measurements show correlation to emulsion stability. (astm.org)
- Viscosity provides a more reliable measure of emulsion stability but water content measurements are more convenient and are largely used in this study. (astm.org)
- As a result, invert emulsions are manufactured to a viscosity level somewhat higher than that of petroleum oils used in similar hydraulic applications. (machinerylubrication.com)
- In particular, the interaction between the size distribution of oil droplets, the viscosity of emulsions and the terminal velocity of spheres has been investigated in the Reynolds number range ∼10 to ∼100. (edu.au)
- Superior high water containing oil continuous microemulsions and emulsions for cleaning contain defined amounts of water, one or more ionic surfactants, and one or more organic solvents so that the compositions have a low conductivity and low viscosity. (patents.com)
- Higher crossflow velocity and lower oil feed concentration decrease the fouling propensity regardless the type of oil used, meanwhile higher viscosity slows down oil emulsion movement on the membrane surface, and bidispersity of the oil emulsion also affects the fouling mechanism. (ntu.edu.sg)
- It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water. (waterpurifyingchemicals.com)
- Broken emulsions will form a foam-like material, called "rag", which retains water which is not part of the stable emulsions. (astm.org)

- Asphaltenes in the crude oil acted as an emulsifier, and stable emulsions were produced. (onepetro.org)
- It was found that very small amounts of PE are required to give stable emulsions, which, along with the sustainability aspect, could make these materials highly attractive for industrial applications. (queensu.ca)
- Consequently, the known polymers that afford w/w emulsion include polyacrylic amides and polyols. (wikipedia.org)
- Traditionally known PDLC consists of oil-in-water emulsion where the oily droplet is a thermotropic liquid crystal such as 4-pentyl-4'-cyanobiphenyl (5CB), and the water phase contains certain polymers. (wikipedia.org)
- This synthetic approach could be extrapolated to loading of other water-soluble drugs into hydrophilic polymers. (springer.com)
