Though they did not examine health outcomes, they noted that "Young infants are more vulnerable to the potential adverse effects of phthalates given their increased dosage per unit body surface area, metabolic capabilities, and developing endocrine and reproductive systems. [31] Finally, particularly low levels of exposure may still have significant effects, and exposure to multiple endocrine disruptors across a variety of compounds (not just phthalates) may synergistically combine to cause a greater effect. Look at other dictionaries: Terephthalate — Ter*eph tha*late, n. The mechanism is one of polar interactions between the polar centres of the phthalate molecule (the C=O functionality) and the positively charged areas of the vinyl chain, typically residing on the carbon atom of the carbon-chlorine bond. [24], Phthalates are also found in medications, where they are used as inactive ingredients in producing enteric coatings.

Studies show that exposure to phthalates is greater from ingestion of certain foods, rather than exposure via water bottles as is most often first thought of with plastic chemicals. [5] This transition to phthalate-free plasticizers has prevented manufacturers from using post-consumer recycled plastic as that recycled content would likely contain phthalates. Following this result, di(2-ethylhexyl) phthalate was listed as a possible carcinogen by IARC, EC, and WHO. Phthalates (US: /ˈθæleɪts/,[1] UK: /ˈθɑːleɪts/[2]), or phthalate esters, are esters of phthalic anhydride. Although the word "phthalate" appears in the name, PETE does not use phthalates as plasticizers. Thanks for your vote! The development of cellulose nitrate plastic in 1846 led to the patent of castor oil in 1856 for use as the first plasticizer. [40][41] In many cases, there are studies that show connections between phthalates and these negative outcomes, as well as studies that show no connection; this is likely due to the research challenges outlined above, and when resolved, could show that phthalate exposure does not cause health effects, or even that they have a much greater effect than currently predicted.

A recent Nature Reviews Endocrinology review paper[30] gives some advice for avoiding exposure to phthalates for concerned people; while they make pains to state that there is no evidence that shows this advice will positively affect one’s health, they suggest (1) eating a balanced diet to avoid ingesting too many endocrine disruptors from a single source, (2) eliminating canned or packaged food in order to limit ingestion of DEHP phthalates leached from plastics, and (3) eliminating use of any personal product such as moisturizer, perfume, cosmetics that contain phthalates. Definitions.net. The authors of a 2008 study "observed that reported use of infant lotion, infant powder, and infant shampoo were associated with increased infant urine concentrations of [phthalate metabolites], and this association is strongest in younger infants. In 1931, the commercial availability of polyvinyl chloride (PVC) and the development of di(2-ethylhexyl) phthalate (DEHP) began the boom of the plasticizer PVC industry. More recently in Europe and the US, regulatory developments have resulted in a change in phthalate consumption, with the higher phthalates (DINP and DIDP) replacing DEHP as the general purpose plasticizer of choice because DIDP and DINP were not classified as hazardous. DEHP, although most applications are shown to pose no risk when studied using recognized methods of risk assessment, has been classified as a Category 1B reprotoxin,[13] and is now on the Annex XIV of the European Union's REACH legislation.

[4] [29] There are possible (though not conclusive) associations between phthalate exposure and adverse child neurodevelopment, including the development of ADHD and autistic behaviors and lower cognitive and motor development. (Chem.) Lower-molecular-weight phthalates, those derived from C3-C6 alcohols, are being gradually replaced in many products in the United States, Canada, and European Union over health concerns. [27][30] Many studies refer to this period of fetal and postnatal development as particularly important to development, but studying this is difficult; it is obviously a huge challenge to measure endocrine disruptor exposure during fetal development and then decades later diagnosing any health problems. In Europe the current figures is 72 %. Conveniently, plastic bottles and polyester thread are actually made of the same substance - polyethylene terephthalate. An endocrine disruptor is a substance that interferes with the normal hormonal mechanisms that allow a biological organism to interact with its environment.

However, Dioctyl terephthalate (a terephthalate isomeric with DEHP) and 1,2-Cyclohexane dicarboxylic acid diisononyl ester (a hydrogenated version of DINP) are available at cost-competitive pricing and with good plasticization properties. "[21] Phthalates were found in almost every sampled home in Bulgaria. In 1994, a Health Canada assessment found that DEHP and another phthalate product, B79P, were harmful to human health. After purification, the monomers can be used to prepare new polyethylene terephthalate. The same study found that DEHP, BBzP, and DnOP were in significantly higher concentrations in dust samples collected in homes where polishing agents were used.

The authors of a 2008 study "observed that reported use of infant lotion, infant powder, and infant shampoo were associated with increased infant urine concentrations of [phthalate metabolites], and this association is strongest in younger infants. In 1931, the commercial availability of polyvinyl chloride (PVC) and the development of di(2-ethylhexyl) phthalate (DEHP) began the boom of the plasticizer PVC industry. More recently in Europe and the US, regulatory developments have resulted in a change in phthalate consumption, with the higher phthalates (DINP and DIDP) replacing DEHP as the general purpose plasticizer of choice because DIDP and DINP were not classified as hazardous. DEHP, although most applications are shown to pose no risk when studied using recognized methods of risk assessment, has been classified as a Category 1B reprotoxin,[13] and is now on the Annex XIV of the European Union's REACH legislation.
