Moisturizers, Emulsifiers, Surfactants, and Stabilizers
Cosmetic-grade raw materials used in skin care products must be tested for quality on potency, identity, and inorganic and organic impurities. A few of the most common methods are derived from the United States Pharmacopoeia-National Formulary (USP-NF), EU Colipa, CTFA methods, the US Federal Register and Japan cosmetic standard method publications.
