Talc (Additional Names: Hydrous Magnesium Silicate)
A naturally occurring mineral, mined from the earth. It may be contaminated with asbestos, a known human carcinogen. Animal studies performed by the National Toxicology Panel have shown some evidence that even asbestos-free talc can be carcinogenic. Perineal use of talc-based body powder has been classified as possibly carcinogenic to humans by the International Agency for Research on Cancer.
Triclosan (Additional Names: 5-Chloro-2-(2,4-dichlorophenoxy)phenol)
An antibacterial agent in toothpaste and antibacterial hand and body washes, as well as a preservative in cosmetics and personal care products. Animal studies have shown that exposure to high doses of triclosan is associated with a decrease in the levels of thyroid hormones. Triclosan may bind to estrogen and/or androgen receptors and thus interfere with the normal function of the endocrine system. There is also evidence that exposure to triclosan contributes to making bacteria resistant to antibiotics. And triclosan imported from India and China may contain dioxins linked to cancer and endocrine-disruption.
