EWG's Cosmetic Safety Database

Skin Deep is a safety guide developed and maintained by the Environmental Working Group (EWG). The Skin Deep database pairs ingredients in more than 25,000 products against 50 definitive toxicity and regulatory databases, making it the largest integrated data resource of its kind. Why did a small nonprofit take on such a big project? Because the FDA doesn't require companies to test their own products for safety.
