This information is taken from a number of sources and has been compiled over a number of years so it will be divided into 2 parts. As a cosmetics formulator I find it interesting but very suspect. But according to FDA statistics, almost 90% of the more than 15,000 ingredients used in personal care products have not been evaluated for safety by the Food and Drug Administration, the Industry-appointed Cosmetic Ingredient Review panel, or anyone else. What this means is that only 10% of the well over 15,000 chemical ingredients used by the cosmetics industry are tested for safety, and it is alleged that many products may contain carcinogens, reproductive toxins, and other toxic chemicals. The FDA has no authority to regulate the personal care products consumers use every day. In fact, according to Deep Skin, the world's largest online cosmetic safety database, one of every 100 products on the market contains ingredients certified by government authorities as known or probable human carcinogens, including shampoos, lotions, make-up foundations, and lipsticks and balms.
