The Skin Deep Cosmetic Safety Database is an online cosmetic safety review search engine created by a non-profit organization, Environmental Working Group, for the purpose of using "information to protect human health and the environment." Products covered include skin care, makeup, hair care, nails, eye care, feminine hygiene, dental and oral hygiene, and fragrances. They provide a database of 62,706 products total, with 7,649 ingredients, 2,701 brands, and 1,817 companies listed.
Searching Skin Deep's database opens up a summary of what EWG found about the product, the score given, the ingredients, company policies, directions from the package, and what the covered ingredients are linked to health-wise. For sunscreen, Skin Deep also includes the effectiveness of protection from UV rays.<ref>http://www.cosmeticsdatabase.com/</ref>
Skin Deep obtains its data from online retailers, manufactures, partner organizations, and various online resources. Product ingredients are found through sources such as The International Cosmetics Ingredient Dictionary and Handbook, the International Nomenclature for Cosmetic Ingredients, Cosmetic Ingredient Review(CRI), and data provided by the manufacturers. For cases of animal testing, EWG references PETA's rating bases. On toxicity, EWG refers to governmental, industrial, and academic journals. To reach their score, Skin Deep inputs "cancer, reproductive/developmental toxicity, neurotoxicity, endocrine disruption potential, allergies/immunotoxicity, restrictions/warnings, organ system toxicity, persistence/bioaccumulation, multiple/additive exposure, mutations, cellular/biochemical changes, ecotoxicity, occupational hazards, irritation, absorption, impurities, and other miscellaneous factors. EWG rates a single factor 0-100 (for example, if a product contains mercury, that product receives a score of ten, the worst, in the reproductive/developmental section). All the factors' scores are weighted to produce a final score.<ref>http://www.cosmeticsdatabase.com/about.php</ref>
