The Environmental Working Group's Skin Deep Website provides a lot of information and ratings on the toxicity (to humans and the environment) on over 69,000 personal care products on the market today, as well as constituent chemicals: [Removed]
The EWG website also provides lots of additional information on toxics, environmental health, food and agriculture, water and energy.
Yes, EWG is an excellent site to use to analyze the toxicity of cosmetics, but It doesn't have much data on Asian cosmetics. The alternative database site I use for Asian cosmetics is "cosDNA".
It essentially functions the same way as EWG, which analyzes the safety of cosmetic items. Amazing tool to use to judge whether or not a particular product is safe for you. I highly recommend both sites to use.
