Wikipedia is a free, web-based, collaborative, multilingual encyclopedia project supported by the non-profit Wikimedia Foundation. Its name is a portmanteau of the words wiki (a technology for creating collaborative websites, from the Hawaiian word wiki, meaning "quick") and encyclopedia. It is an excellent source for information about ingredients and chemicals used in the cosmetic, skin care and hair care industries.

It has a fairly extensive set of pages on common skin care ingredients such as parabens and phthlates, with quite detailed information and is quite current. Check it out!
