ABSTRACT:
The invention relates to mixtures of long-chain alkyl phosphates of the formula ##STR1## in which R is a mixture of C.sub.12 -C.sub.22, preferably C.sub.14 -C.sub.20, straight-chain alkyl radicals and C.sub.12 -C.sub.22, preferably C.sub.14 -C.sub.20, .beta.-branched alkyl radicals, and X and Y are identical or different and are hydrogen, alkali metal or an equivalent of an alkaline earth metal, ammonium, mono-, di- or tri-alkylammonium or an organic base, or X and/or Y are as defined under R. These esters are suitable as emulsifiers, in particular for oil-in-water emulsions of a cosmetic pharmaceutical nature.
