An in depth article on phthalates can be found on the
www.health-report.co.uk website.
The CDC's John Brock, the head researcher on the phthalate study, said that his "biggest concern was that the highest levels of exposure were in women of child-bearing age." ("Concerns over chemicals in cosmetics", Francesca Lyman, October 4, 2000) Phthalates are regulated as toxic substances under environmental laws that limit their discharge into air, land, and water, but there are NO limitations on the amount of phthalates used in consumer products, including cosmetics. Health effects of phthalates include damage to the liver and kidneys, birth defects, decreased sperm counts, testicular cancer, early puberty onset in girls, early breast development in girls and boys, and other reproductive disorders.; MSDS: WARNING!
