  • Patent number: 6448297
    Abstract: The invention relates to alkyl phosphates, in particular their mixtures, of the formula in which R is C12-C22-alkyl, preferably C14-C18-alkyl, X is a group of the formulae NH3R1, NH2R2R3 or NHR4R5R6, Y is as defined for R or is as defined for X, and R1 is C8-C22-alkyl, R2 and R3 are C1-C22-alkyl or cyclohexyl, and R4, R5 and R6 are C1-C4-alkyl. These compounds, in particular the mixtures of mono- and diesters, are suitable as emulsifiers in the preparation of aqueous emulsions.
