A novel phosphoric ester represented by the following formula (I): ##STR1## is produced by halogenating the hydroxyl group of a monoalkyl phosphoric acid, reacting the halogenated product with N-benzoyloxycarbonyl serine ester and then removing protecting groups for the carboxyl group and amino group. According to the present production process, the phosphoric ester can be obtained inexpensively at a high yield and high purity. Further, the phosphoric ester has a structure similar to that of the phospholipid and has nitrogen-containing polar groups such as amino group in one molecule, so that it has excellent emulsification ability and moisture keeping function. It is thus useful as emulsifiers, humectants and the like.
