Uses

Vitamin A palmitate (CAS NO.79-81-2) is a synthetic alternate for retinyl acetate in vitamin A supplements, and is available in oily or dry forms. It is also a constituent of some topically-applied skin care products. Palmitate is an antioxidant and a vitamin A compound added to low fat milk and other dairy products to replace the vitamin content lost through the removal of milk fat. Palmitate is attached to the alcohol form of vitamin A, retinol, in order to make vitamin A stable in milk.
