The listing of cosmetic ingredients (official INCI names) is made on the basis of the function each of them performs in finished cosmetic products. Many ingredients have multiple functions in formulations and therefore are included in several function groupings. The use of an ingredient for functions other than those included here may be completely acceptable. Inclusion of an ingredient in a particular function category does not imply that the ingredient is "approved," "certified," or "endorsed" for this use by any organization or governmental body in the U.S. or any other country. The 74 groups contain a total of more 34,000 listings.
