Phthalates are a class of chemical used to soften plastics. They are one of a group of substances called plasticizers, which make plastic more malleable and can be found in everything from margarine tubs to kids’ toys.
Phthalates have been in the news a lot lately. Bisphenol A, a type of phthalate, was recently banned by the Canadian government. The ban was the result of increasing evidence that BPA could leach out of baby bottles or other infant-related items. Once in the body, BPA acts as an endocrine disruptor, which could lead to chronic toxicity problems. Animal studies show that exposure early in life is particularly critical to the negative effects of BPA, leaving infants who are fed formula from plastic bottles containing BPA at the greatest risk.
While BPA is a phthalate that has been clearly identified as a problem, other phthalates continue to be in general use. In fact, any product which uses PVC plastic will have phthalates in it. PVC plastics are in everything from the liners of canned foods to medical devices to building materials and cleaners. You may even find phthalates in personal care products.
Unfortunately, with our exposure to these substances constantly going up, scientists have found yet another reason to avoid phthalates: they may make skin reactions worse. Animal studies have shown that newborn mice exposed to DEHP (which is a type of phthalate) in utero developed more serious dermatitis than those not exposed.
Researchers believe that the results of this study indicate a possible explanation for the significant rise in skin allergies – the prevalence of phthalates such as DEHP in the environment. DEHP is used in such products as vinyl flooring and carpet backing. It has become ubiquitous in our homes. As a result, this chemical is even found in house dust.
Science Daily recently reported that various phthalates had serious effects on lab animals, including male infertility, undescended testicles and other reproductive tract issues. ConsumerReports.org has indicated that phthalates are associated with both liver cancer and fetal development. Phthalates are also known to interfere with male hormones.
