About
An aluminum salt of acetic acid used in cosmetics as an astringent and pH adjuster, though its bioavailability of aluminum raises concerns in the context of EU restrictions on aluminum in certain product types.
Aluminum diacetate (also known as aluminum acetate or basic aluminum acetate) is used in cosmetic formulations as an astringent and antimicrobial preservative. The compound releases small amounts of aluminum ions which precipitate proteins, creating the astringent sensation. Under EU cosmetics regulation, aluminum compounds are under review for skin absorption concerns, particularly in aerosol and leave-on products. The compound has a PubChem safety score of 75.
