About

An emulsifying phosphate ester derived from myristyl alcohol that helps create stable, non-irritating cosmetic emulsions.

Dimyristyl Phosphate is the phosphate ester of myristyl alcohol (tetradecanol), a C14 saturated fatty alcohol. Like other fatty alcohol phosphate esters (such as cetyl phosphate), it functions as an emulsifier and skin conditioning agent. The C14 chain length provides a balance between emulsifying power and mildness. The substance is not subject to EU restrictions and is used in cosmetic formulations including creams, lotions, and color cosmetics.

Skin benefits
