ForeignPolicy.com takes a look at everyday beauty products that aren’t worth the risk, including skin whitening cream, which may contain mercury or hydroquinone, a chemical used in photo processing. “Extended exposure to hydroquinone can backfire, leaving large dark patches of skin, or possibly worse: It has been shown to cause cancer in lab animals. In 2005, a pair of Dutch researchers referred to the widespread use of hydroquinone in skin whiteners as ‘a potential time bomb.'”
Meanwhile, a biochemist who researches cosmetics and toiletries says women who use make-up daily are absorbing almost 5 lb of chemicals a year into their bodies and the combination of chemicals “could be much greater than the sum of the individual parts.” (Via the F-Word.)
And E Magazine reports on the political battle to ban certain chemical compounds from children’s toys and feeding products. Of particular concern are phthalates, which are also present in some cosmetics.
“Environmentalists and environmentally minded legislators are beginning to worry about long-term exposure to the chemical compounds,” writes Brita Belli. “Specifically, they worry about diisononyl phthalate or DINP, a plasticizer commonly used in soft vinyl products made for babies, such as bath books, rubber ducks and teething rings as well as bisphenol A (BPA), a building block for polycarbonate plastic used in shatter-resistant baby bottles. Studies have linked BPA to hormone disruption in rats, to increased breast cancer and prostate cancer cell growth, to early onset puberty and obesity; studies with phthalates have linked the chemicals to rodent cancers and genital abnormalities, especially in males.”
Yet In 2002, writes Kara Alaimo, “researchers in Chicago tested 72 brand-name cosmetics and found that 52 contained phthalates, but none listed the chemical on their label.”
In August 2005, researchers including University of Rochester epidemiologist Shanna Swan published the first study to examine mothers’ prenatal exposure to phthalates in relation to the genital development of their baby boys. The small study found subtle changes suggesting the development of the genitals of boys whose mothers had high levels of phthalates was less complete than in those whose mothers were exposed to lower levels of phthalates.
Swan says determining whether exposure to phthalates is contributing to increasing rates of male infertility and testicular cancer–as studies on rodents currently suggest — is “one of the most important items on the research agenda.”
