Recent progress in safety evaluation studies on plasticizers and plastics and their controlled use in Japan. (1/178)

Recent experimental studies in Japan on the evaluation of potential health hazards from phthalate esters used in manufacturing poly (vinyl chloride) as well as several plastics for medical devices and for food containers and packages were introduced. Development of pulmonary granuloma formation after intravenous injection of diethylhexyl phthalate was assumed to be dependent on the particle size of the phthalate in vehicle used. Dietary administration of large amount of diethylhexyl phthalate and dibutyl phthalate produced renal cysts in mothers and in descendants in reproduction studies in mice. Cytotoxicity and mutagenicity of the phthalates and several plastics and resins were also examined by in vivo and in vitro studies. Hematological parameters examined in rabbits after repeated intravenous injection of diethylhexyl phthalate and after implantation of plastics in aorta for 3--6 months did not show any significant change. A slow decrease of radioactivity was observed in adipose tissue of rats following oral administration of 14C-labeled diethylhexyl phthalate. tthe administrative action on phthalates by the Japanese Ministry of Health and Welfare is briefly reviewed.  (+info)

Quantitative evaluation of alternative mechanisms of blood and testes disposition of di(2-ethylhexyl) phthalate and mono(2-ethylhexyl) phthalate in rats. (2/178)

Di(2-ethylhexyl) phthalate (DEHP), a commercially important plasticizer, induces testicular toxicity in laboratory animals at high doses. After oral exposure, most of the DEHP is rapidly metabolized in the gut to mono(2-ethylhexyl) phthalate (MEHP), which is the active metabolite for induction of testicular toxicity. To quantify the testes dose of MEHP with various routes of exposure and dose levels, we developed a physiologically based pharmacokinetic (PBPK) model for DEHP and MEHP in rats. Tissue:blood partition coefficients for DEHP were estimated from the n-octanol: water partition coefficient, while partition coefficients for MEHP were determined experimentally using a vial equilibration technique. All other parameters were either found in the literature or estimated from blood or tissue levels following oral or intravenous exposure to DEHP or MEHP. A flow-limited model failed to adequately simulate the available data. Alternative plausible mechanisms were explored, including diffusion-limited membrane transport, enterohepatic circulation, and MEHP ionization (pH-trapping model). In the pH-trapping model, only nonionized MEHP is free to become partitioned into the tissues, where it is equilibrated and trapped as ionized MEHP until it is deionized and released. All three alternative models significantly improved predictions of DEHP and MEHP blood concentrations over the flow-limited model predictions. The pH-trapping model gave the best predictions with the largest value of the log likelihood function. Predicted MEHP blood and testes concentrations were compared to measured concentrations in juvenile rats to validate the pH-trapping model. Thus, MEHP ionization may be an important mechanism of MEHP blood and testes disposition in rats.  (+info)

Plasticizers increase adhesion of the deteriogenic fungus Aureobasidium pullulans to polyvinyl chloride. (3/178)

Initial adhesion of fungi to plasticized polyvinyl chloride (pPVC) may determine subsequent colonization and biodeterioration processes. The deteriogenic fungus Aureobasidium pullulans was used to investigate the physicochemical nature of adhesion to both unplasticized PVC (uPVC) and pPVC containing the plasticizers dioctyl phthalate (DOP) and dioctyl adipate (DOA). A quantitative adhesion assay using image analysis identified fundamental differences in the mechanism of adhesion of A. pullulans blastospores to these substrata. Adhesion to pPVC was greater than that to uPVC by a maximum of 280% after a 4-h incubation with 10(8) blastospores ml(-1). That plasticizers enhance adhesion to PVC was confirmed by incorporating a dispersion of both DOA and DOP into the blastospore suspension. Adhesion to uPVC was increased by up to 308% in the presence of the dispersed plasticizers. Hydrophobic interactions were found to dominate adhesion to uPVC because (i) a strong positive correlation was observed between substratum hydrophobicity (measured by using a dynamic contact angle analyzer) and adhesion to a range of unplasticized polymers including uPVC, and (ii) neither the pH nor the electrolyte concentration of the suspension buffer, both of which influence electrostatic interactions, affected adhesion to uPVC. In contrast, adhesion to pPVC is principally controlled by electrostatic interactions. Enhanced adhesion to pPVC occurred despite a relative reduction of 13 degrees in the water contact angle of pPVC compared to that of uPVC. Furthermore, adhesion to pPVC was strongly dependent on both the pH and electrolyte concentration of the suspension medium, reaching maximum levels at pH 8 and with an electrolyte concentration of 10 mM NaCl. Plasticization with DOP and DOA therefore increases adhesion of A. pullulans blastospores to pPVC through an interaction mediated by electrostatic forces.  (+info)

Retrospective evaluation of alpha 2u-globulin accumulation in male rat kidneys following high doses of diisononyl phthalate. (4/178)

Diisononyl phthalate (DINP), a widely used plasticizer, has been evaluated in two chronic studies in rats and one in mice. In the early 1980s, Exxon found no carcinogenic potential at the estimated maximum tolerated dose (MTD) of 0.6% (307 mg/kg/ day for male rats) administered in the diet of rats for 2 years. A recent study conducted at dietary levels up to 1.2% DINP (733 mg/kg/d for male rats) reported kidney tumors in male rats at the high treatment level, but not in female rats nor mice of either sex. Because these tumors occurred only in male rats, and only at high doses, the male rat-specific alpha 2u-globulin (alpha2UG) mechanism of action was investigated. Technological advances in immunohistochemical staining and computerized image analysis techniques permitted measuring the accumulation of alpha2UG in archived kidneys from the earlier Exxon study. Using archived tissue obtained at the 12-month interim sacrifice, we identified a dose-dependent accumulation of alpha2UG in specific regions of male rat kidneys only. An increase in cell proliferation was confirmed by immunohistochemical detection of proliferating-cell nuclear antigen (PCNA) and was confined to the areas of alpha2UG accumulation. H and E-stained sections revealed tubular epithelial hypertrophy and regeneration, consistent with the immunohistopathology findings. These findings are consistent with the alpha2UG mechanism of tumorigenesis, which is not regarded as relevant for humans. Thus, exposure to DINP produced a dose-dependent alpha2UG accumulation in male rat kidneys, significant at a dietary level of 0.6% and a likely mechanism for the kidney tumors seen only in male rats administered higher dietary levels of DINP.  (+info)

Influence of plasticizer-free CAPD bags and tubings on serum, urine, and dialysate levels of phthalic acid esters in CAPD patients. (5/178)

OBJECTIVES: To evaluate the impact of a plasticizer-free device on exposure to di-(2-ethylhexyl) phthalate (DEHP) and its major metabolites in patients on continuous ambulatory peritoneal dialysis (CAPD). DEHP is the most commonly used plasticizer in polyvinyl chloride (PVC) products; it is added to CAPD bags in order to improve the flexibility of the material. Since DEHP leaches out of the plastic matrix, patients on CAPD are exposed to considerable amounts of DEHP and its metabolites. DESIGN: A prospective cross-over study. SETTING: Department of nephrology in a teaching hospital. PARTICIPANTS: Six patients (4 female, 2 male) stable on peritoneal dialysis (PD) for at least 6 months. INTERVENTIONS: Patients were switched from a plasticizer-containing PVC CAPD system (A.N.D.Y. Plus, Fresenius Medical Care, Bad Homburg, Germany) to a polyolefine-made plasticizer-free system (stay-safe, Fresenius). MAIN OUTCOME MEASURES: Prior to and 42 days after the switch, 24-hour effluent dialysate and urine collections were performed and 10 mL blood was drawn. Concentrations of DEHP, mono-(2-ethylhexyl) phthalate (MEHP), phthalic acid (PA), and 2-ethylhexanol (2-EH) in urine, dialysate, and serum were determined using gas chromatography/mass spectrometry. RESULTS: Complete data were obtained from 5 patients. Serum levels of PA decreased significantly during the study period (0.137 +/- 0.078 mg/L vs 0.124 +/- 0.049 mg/L, p = 0.04), and the respective levels of DEHP decreased insignificantly (0.097 +/- 0.076 mg/L vs 0.069 +/- 0.046 mg/L, p = 0.07), whereas the concentrations of MEHP and 2-EH remained unchanged. Urine concentrations of PA were high (0.81 +/- 0.69 mg/L) but did not change substantially (0.70 +/- 0.50 mg/L). Effluent dialysate concentrations of MEHP and PA decreased significantly (0.0176 +/- 0.004 mg/L vs 0.0040 +/- 0.0007 mg/L, p = 0.043 and 0.158 +/- 0.056 mg/L vs 0.111 +/- 0.051 mg/L, p = 0.043, respectively). CONCLUSIONS: Although PD patients seem to be exposed to other sources of phthalates in addition to dialysis, use of plasticizer-free devices may help to reduce potentially immunosuppressive exposure to phthalate esters.  (+info)

Identification of phthalate esters in the serum of young Puerto Rican girls with premature breast development. (6/178)

Premature breast development (thelarche) is the growth of mammary tissue in girls younger than 8 years of age without other manifestations of puberty. Puerto Rico has the highest known incidence of premature thelarche ever reported. In the last two decades since this serious public health anomaly has been observed, no explanation for this phenomenon has been found. Some organic pollutants, including pesticides and some plasticizers, can disrupt normal sexual development in wildlife, and many of these have been widely used in Puerto Rico. This investigation was designed to identify pollutants in the serum of Puerto Rican girls with premature thelarche. A method for blood serum analysis was optimized and validated using pesticides and phthalate esters as model compounds of endocrine-disrupting chemicals. Recovery was > 80% for all compounds. We performed final detection by gas chromatography/mass spectrometry. We analyzed 41 serum samples from thelarche patients and 35 control samples. No pesticides or their metabolite residues were detected in the serum of the study or control subjects. Significantly high levels of phthalates [dimethyl, diethyl, dibutyl, and di-(2-ethylhexyl)] and its major metabolite mono-(2-ethylhexyl) phthalate were identified in 28 (68%) samples from thelarche patients. Of the control samples analyzed, only one showed significant levels of di-isooctyl phthalate. The phthalates that we identified have been classified as endocrine disruptors. This study suggests a possible association between plasticizers with known estrogenic and antiandrogenic activity and the cause of premature breast development in a human female population.  (+info)

The plasticizer diethylhexyl phthalate induces malformations by decreasing fetal testosterone synthesis during sexual differentiation in the male rat. (7/178)

Phthalate esters (PE) such as DEHP are high production volume plasticizers used in vinyl floors, food wraps, cosmetics, medical products, and toys. In spite of their widespread and long-term use, most PE have not been adequately tested for transgenerational reproductive toxicity. This is cause for concern, because several recent investigations have shown that DEHP, BBP, DBP, and DINP disrupt reproductive tract development of the male rat in an antiandrogenic manner. The present study explored whether the antiandrogenic action of DEHP occurs by (1) inhibiting testosterone (T) production, or by (2) inhibiting androgen action by binding to the androgen receptor (AR). Maternal DEHP treatment at 750 mg/kg/day from gestational day (GD) 14 to postnatal day (PND) 3 caused a reduction in T production, and reduced testicular and whole-body T levels in fetal and neonatal male rats from GD 17 to PND 2. As a consequence, anogenital distance (AGD) on PND 2 was reduced by 36% in exposed male, but not female, offspring. By GD 20, DEHP treatment also reduced testis weight. Histopathological evaluations revealed that testes in the DEHP treatment group displayed enhanced 3ss-HSD staining and increased numbers of multifocal areas of Leydig cell hyperplasia as well as multinucleated gonocytes as compared to controls at GD 20 and PND 3. In contrast to the effects of DEHP on T levels in vivo, neither DEHP nor its metabolite MEHP displayed affinity for the human androgen receptor at concentrations up to 10 microM in vitro. These data indicate that DEHP disrupts male rat sexual differentiation by reducing T to female levels in the fetal male rat during a critical stage of reproductive tract differentiation.  (+info)

Application of sintered titanium alloys to metal denture bases: a study of titanium powder sheets for complete denture base. (8/178)

The purpose of this study was the fabrication of titanium powder sheets to enable the application of sintered titanium alloys as metal denture bases. The effects of titanium particle shape and size, binder content, and plasticizer content on the surface smoothness, tensile strength and elongation of titanium powder sheets was investigated. To select a suitable ratio of powdered metal contents for application as a metal denture base, the effects of aluminum content in Ti sheets and various other powder metal contents in Ti-Al sheets on the density, sintering shrinkage, and bending strength were evaluated. Based on the results of the above experiments, we developed a mixed powder sheet composed of 83Ti-7Al-10Cr with TA45 titanium powder (atomized, -45 microm), and 8 mass% binder content. This titanium alloy sheet had good formability and ductility. Its sintered titanium alloy had a density of 3.2 g/cm3, sintering shrinkage of 3.8%, and bending strength of 403 MPa. The titanium alloy sheet is clinically acceptable for fabricating denture bases.  (+info)

Diisononyl phthalate (DINP), di (2-ethyl) hexyl phthalate (DEHP), n-octyl phthalate (DNOO), isodecyl phthalate (DIDP) Butyl phthalate (BBP) and dibutyl phthalate (DBP) are collectively called phthalates (or salts), and are commonly used plasticizers for PVC products. Plasticizers are added to PVC to improve the softness, cold resistance, and light stability of PVC. The amount of plasticizer added for different uses of PVC products is different. For example, the weight ratio of phthalates in PVC for food packaging is about 28%, and flexible plastics for toys reach 35% to 40%. Studies have shown that phthalate-containing PVCs are easily released when exposed to grease or at high temperatures above 100 ° C. Due to different recognition of the hazards of phthalate ester-containing PVC, the scope and degree of recognition of its impact are different, so the use restrictions of phthalate ester-containing PVC in different countries are also different. Management regulations and requirements The ...

Plasticizers (UK: plasticisers) or dispersants are additives that increase the plasticity or decrease the viscosity of a material. These are the substances which are added in order to alter their physical properties. These are either liquids with low volatility or may be even solids. They decrease the attraction between polymer chains to make them more flexible. Over the last 60 years more than 30,000 different substances have been evaluated for their plasticizing properties. Of these, only a small number - approximately 50 - are today in commercial use. The dominant applications are for plastics, especially polyvinyl chloride (PVC). The properties of other materials are also improved when blended with plasticizers including concrete, clays, and related products. According to 2014 data, the total global market for plasticizers was 8.4 million metric tonnes including 1.3 million metric tonnes in Europe. Plasticizers for plastics are additives, most commonly phthalate esters in PVC applications. ...
Abstract Due to their versatility, robustness, and low production costs, plastics are used in a wide variety of applications. Plasticizers are mixed with polymers to increase flexibility of plastics. However, plasticizers are not covalently bound to plastics, and thus leach from products into the environment. Several studies have reported that two common plasticizers, bisphenol A (BPA) and phthalates, induce adverse health effects in vertebrates; however few studies have addressed their toxicity to non-mammalian species. The aim of this review is to compare the effects of plasticizers in animals, with a focus on aquatic species. In summary, we identified three main chains of events that occur in animals exposed to BPA and phthalates. Firstly, plasticizers affect development by altering both the thyroid hormone and growth hormone axes. Secondly, these chemicals interfere with reproduction by decreasing cholesterol transport through the mitochondrial

Show more ,Phthalates, used in medical devices (MDs), have been identified as reproductive and developmental toxicants. Their toxicity varies somewhat depending on the specific phthalate and is in part linked to the activation of Peroxisome Proliferating-Activated Receptors (PPARs). So, the use of MDs containing targeted phthalates such as di(2-ethylhexyl) phthalate (DEHP) has been challenged by European directive 2007/47/EC. Therefore, MDs manufacturers were forced to quickly find replacement plasticizers. However, very little toxicological and epidemiological studies are available on human health. So, we proceeded to dock these chemicals in order to identify compounds that are likely to interact with PPARs binding sites. The results obtained are generally very mixed on the harmlessness of these alternatives. Moreover, no data exist on the biological effects of their possible metabolites. As DEHP toxicity resulted mainly from its major metabolites, generalizing the use of these plasticizers ...

The fatigue fracture surface micromorphology of poly(vinyl chloride) (PVC) was studied as a function of molecular weight (M), plasticizer content, and residual orientation, with particular attention given to how these variables affect the formation of discontinuous growth bands (DGBs). Discontinuous growth bands, which form on a number of polymeric solids under cyclic loading, represent successive increments of crack extension through a craze zone. As expected, DGB width showed little change in size over the molecular weight range or specimen orientations examined and increased in size with increasing plasticizer content. On the other hand, the cyclic stability of these bands increased markedly with an increase in molecular weight, but to a lesser extent with additions of a plasticizer. The internal structure of the bands became more ragged with increasing M, whereas the addition of a plasticizer reestablished the crisp and well-defined micromorphology associated with DGBs in low-M polymers. ...
Polylactic acid (PLA) is becoming an increasingly important biopolymer for packaging applications. PLA brittleness limits its applicability. This study evaluated PLA properties with increasing amounts of added polyethylene glycol (PEG) plasticizer. Oxygen transmission rate (OTR) of cast films was determined using the newly available Dynamic Accumulation (DA) method. Arrhenius temperature sensitivity of OTR and polymer Permeability was also determined. Permeability of neat PLA is 4.848 ml mm (STP)/m2 s kPa; hence, 4.84 ml mm (STP)/m2 s kPa, 4.07 ml mm (STP)/m2 s kPa and 5.42 ml mm (STP)/m2 s kPa by adding PEG 1 %, 5% and 10% respectively. The main conclusion from this work is increasing PEG will enhance the PLA permeability number but excess PEG in PLA film will decrease the permeability number.

The PVC membrane of an ion-selective electrode (ISE) sensitive to dibasic phosphate ions (HPO4-ISE) has not been optimized for maximum selectivity, sensitivity, and useable ISE lifetime and further work was necessary to improve its performance. Two areas of investigation are reported here: include the parameters for the lipophilicity of the plasticizer compound used and the amount of cyclic polyamine ionophore incorporated in the PVC membrane. Six candidate plasticizers with a range of lipophilicity were evaluated for their effect on the useable lifetime, sensitivity, and selectivity of the ISE against 13 different anions. Selectivity was determined by a modified fixed interferent method, sensitivity was determined without interferents, and the usable lifetime evaluated at the elapsed time where 50% of the HPO4-ISE failed (L50). The results show that choosing a plasticizer that has a lipophilicity similar to the ionophores results in the best selectivity and sensitivity and the longest L50.

Given the widespread occurrence of phthalates in the aquatic environment, fish are also likely to be exposed to phthalates via the water column, food and/or via the sediments, depending on their ecological niche. In support of this, a study in wild fish in The Netherlands measured median concentrations of DEHP and DBP at 1.7 and 1.0 µg kg−1 (wet wt.), respectively, with 95th percentile values reaching up to 141 µg DEHP kg−1 and 26 µg DBP kg−1 (wet wt.) (Peijnenburg & Struijs 2006). Laboratory studies have further shown that phthalates bioconcentrate in fish. For example, the BCF for DEHP was 120 in the carp and for BBP, 9.4 in bluegill sunfish (Staples et al. 1997). The presence of phthalates in wild fish and their ability to concentrate in body tissues demonstrate their potential to induce adverse effects on the health of wild populations, but there has been little bearing on this expectation.. Very few studies have comprehensively addressed the biological effects of phthalates on ...

Introduction. Phthalates are among the most widely used industrial chemicals in existence. They are used principally as plasticizers, to impart flexibility, workability, and durability to polymers, but they can also be found in products such as adhesives, inks, and cosmetics, munitions, industrial and lubricating oil, as well as solvents in perfumes and paints and additives in hair-sprays and insect repellent (Shanker et al., 1985; Ling et al., 2007; Huang et al., 2008). To provide flexibility phthalate esters are not chemically bonded to resin and therefore are easily released (Yuan et al., 2008). The most commonly used phthalate plasticizers are di-2-ethylhexyl phthalate (DEHP) and di-n-butyl phthalate (DBP) with the others used only for selective applications (ATSDR, 2006).. There has been growing interest in the unusual ubiquity of phthalates in the environment (Fatoki and Vernon, 1990; Fatoki and Ogunfowokan, 1993a) and their wide range of toxicological characteristics (Blount et al., ...

In this study, the film forming behaviour of low amylose (LA) and high amylose (HA) starches was studied. The starch-alone and a blend of plasticizer (polyol)-starch films were developed by gelatinising at various temperatures and casting at 25 °C. The starch-plasticizer films contained glycerol and xylitol either individually or in 1:1 combination. The concentration of plasticizer used was 15%, 20% and 30% for LA films while it was 20%, 30% and 40% for HA films on dry solid basis. The HA-glycerol films retained the highest moisture content among all the films. The HA films exhibited higher glass transition temperature, higher tensile strength, higher modulus of elasticity and lower elongation at break than those obtained from LA starch. The tensile strength and modulus of elasticity decreased and the elongation increased with increasing plasticizer concentrations above 15% on dry solid basis regardless the starch type. Low water vapour permeability was evident in LA and HA films plasticized by ...
Diethylhexyl phthalate (DEHP) is widely used as a plasticizer in consumer products and is known to disturb the development of the male reproductive system in rats. The mechanisms by which DEHP exerts these effects are not yet fully elucidated, though some of the effects are related to reduced fetal testosterone production. The present study investigated the effects of four different doses of DEHP on fetal testicular histopathology, testosterone production and expression of proteins and genes involved in steroid synthesis in fetal testes. Pregnant Wistar rats were gavaged from GD 7 to 21 with vehicle, 10, 30, 100 or 300 mg/kg bw/day of DEHP. In male fetuses examined at GD 21, testicular testosterone production ex vivo and testicular testosterone levels were reduced significantly at the highest dose. Histopathological effects on gonocytes were observed at 100 and 300 mg/kg bw/day, whereas Leydig cell effects were mainly seen at 300 mg/kg bw/day. Quantitative RT-PCR revealed reduced testicular mRNA ...

The purpose of this study was to determine the effect of PMMA polymer on dynamic viscoelasticity and plasticizer leachability of PEMA-based tissue conditioners. One PEMA polymer and one PMMA polymer were used in powder form with four formulations. The combination of 80 wt% ATBC, 15 wt% BPBG and 5 wt% ethyl alcohol was used as the liquid phase. The dynamic viscoelasticity and plasticizer leaching of each specimen were measured after 0, 1, 3, 7, and 14 days of immersion (37°C distilled water) using DMA and HPLC. A significant difference was found among the materials in the dynamic viscoelasticity and leaching of plasticizer. The materials containing 10 wt% PMMA showed the most stable dynamic viscoelasticity, and showed the lowest leaching of plasticizer. The results suggest that the addition of the PMMA polymer to the powder of a tissue conditioner can improve the durability of the PEMA-based tissue conditioner.. ...

Children are constantly exposed to many chemicals via the products they come in contactwith in their everyday life. One chemical group is phthalates, the most commonly usedplasticisers in the world. Phthalates are used mainly in PVC plastic products like floors, toys,food containers and wallpaper but they are also used in rubber, glue, paint, cables etc. Sincethese chemicals are weakly chemically bound to the PVC they can leak and migrate to the air,food, water and skin. Children are exposed to phthalates mainly through food, but because ofthe hand to mouth behaviour they are also exposed via dust inhalation and dust ingestion.About ten years ago regulations of the most toxic phthalates in toys and child care productswere implemented in the EU and from February 2015 it is a general prohibition for the use ofDEHP (diethylhexyl phthalate), DnBP (di-n-butyl phthalate), DiBP (diisobutyl phthalate) andBBzP (butyl benzyl phthalate).

Di-(2-ethylhexyl) phthalate (DEHP) is used to increase the flexibility of plastics for industrial products. However, the illegal use of the plasticizer DEHP in food and drinks has been reported in Taiwan in 2011. In order to assess the exact extent of the absorption of DEHP via the oral route, the aim of this study is to develop a reliable and validated ultra performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS) method to evaluate the oral bioavailability of DEHP in rats. The optimal chromatographic separation of DEHP and butyl benzyl phthalate (BBP; used as internal standard) were achieved on a C18 column. The mobile phase was consisted of 5 mM ammonium acetate-methanol (11:89, v/v) with a flow rate of 0.25 mL/min. The monitoring ion transitions were m/z 391.4 → 149.0 for DEHP and m/z 313.3 → 149.0 for BBP. The mean matrix effects of DEHP at low, medium and high concentrations were 94.5 ± 5.7% and 100.1 ± 2.3% in plasma and feces homogenate samples, respectively. In

Phthalates are esters of 1,2-benzoldicarbonic acid (ortho-phthalic acid). The chemical structure of phthalates can be characterised by a planar aromatic ring with two slightly mobile side chains. For phthalates, in general, side chains are mainly alkyl groups with a secondary role played by allyl, benzyl, phenyl, cycloalkyl and alkoxy groups. With alkyl phthalates, a further distinction can be made between branched and unbranched side chains.. In the early 1980s, annual, world-wide production of phthalate esters was estimated to be 20 million tonnes (Schmitzer et al, 1988), although it may now be closer to 5 million tonnes (Lewis et al 1998). The total consumption of phthalate esters in the UK was estimated to be 122,000 tonnes in 1989, of which 54% was DEHP and DIOP (Brooke et al 1991).. Phthalates esters are manufactured world-wide on a large scale, being mainly produced for use as plasticisers in resins and polymers, especially as a softener in PVC (87% of the total production of phthalates ...

Biodegradation of DEP in soil occurs by sequential hydrolysis of the two diethyl chains of the phthalate to produce monoethyl phthalate, followed by phthalic acid. This reaction occurs very slowly in an abiotic environment. Thus there exists an alternative pathway of biodegradation which includes transesterification or demethylation by microorganisms, if the soil is also contaminated with methanol, that would produce another three intermediate compounds, ethyl methyl phthalate, dimethyl phthalate and monomethyl phthalate. This biodegradation has been observed in several soil bacteria.[10] Some bacteria with these abilities have specific enzymes involved in the degradation of phthalic acid esters such as phthalate oxygenase, phthalate dioxygenase, phthalate dehydrogenase and phthalate decarboxylase.[20] The developed intermediates of the transesterification or demethylation, ethyl methyl phthalate and dimethyl phthalate, enhance the toxic effect and are able to disrupt the membrane of ...
Phosphate flame retardants and plasticizers (PFRs) are additives used in a wide range of polymers. Important representatives, such as tris(2-butoxyethyl) phosphate (TBOEP), triphenyl phosphate (TPHP), tris(2-chloroethyl) phosphate (TCEP), tris(1-chloro-2-propyl) phosphate (TCIPP), tris(1,3-dichloro-2propyl) phosphate (TDCIPP), have been found in the indoor environment at high levels. Biotransformation of these PFRs needs to be investigated because it can be a major determinant of their bioavailability and toxicity in humans. TBOEP, TPHP, TCEP, TCIPP and TDCIPP were incubated with human liver S9 fraction and microsomes. Supernatants were analyzed using a liquid chromatography coupled to a quadrupoletime-of-flight mass spectrometer. Chromatograms were scanned for the presence of Phase-I and Phase-II metabolites and tentatively identified based on mass accuracy of the molecular formula, isotopic pattern, and MS/MS spectra. The two major metabolites of TBOEP were products of O-dealkylation and of ...

The influence of poly(ethylene glycol) (PEG) plasticiser content and molecular weight on the physicochemical properties of films cast from aqueous blends of poly(methyl vinyl ether-co-maleic acid) was investigated using thermal analysis, swelling studies, scanning electron microscopy (SEM) and attenuated total reflectance (ATR)-Fourier transform infrared (FTIR) spectroscopy. FTIR spectroscopy revealed a shift of the C=O peak from 1708 to 1731 cm(-1), indicating that an esterification reaction had occurred upon heating, thus producing crosslinked films. Higher molecular weight PEGs (10,000 and 1000Da, respectively), having greater chain length, producing hydrogel networks with lower crosslink densities and higher average molecular weight between two consecutive crosslinks. Accordingly, such materials exhibited higher swelling rates. Hydrogels crosslinked with a low molecular weight PEG (PEG 200) showed rigid networks with high crosslink densities and, therefore, lower swelling rates. Polymer: ...

0007] Patent U.S. Pat. No. 5,589,526 describes, for example, a masterbatch comprising an elastomeric polymer, such as the copolymer of ethylene and vinyl acetate, from 30 to 50% by weight of the composition of an organic peroxide, a plasticizer, a polyoctenamer and fillers. The masterbatch described is manufactured by a mixer for the thermoplastics by melting the polymers with the plasticizer and by adding the peroxide and then the fillers. The manufacturing process is lengthy and complex: as a phenomenon of self-heating of the composition is observed when this type of melt processing is used, it is therefore necessary to confirm that the temperature remains stable and is sufficiently low for premature crosslinking not to take place. Furthermore, the presence of plasticizer is necessary in order to reduce the self-heating, which may be a nuisance in sonic applications. Finally, the presence of large amounts of fillers, such as chalk and silicic acid, and polyoctenamer, which is a highly ...
