    摘要: A phosphoric ester of the following formula (I): ##STR1## in which R.sub.1 represents a saturated or unsaturated, linear or branched and substituted or unsubstituted hydrocarbon group having from 8 to 32 carbon atoms, R.sub.2, R.sub.3 and R.sub.4 are the same or different and represent a saturated or unsaturated hydrocarbon group having from 1 to 4 carbon atoms, R.sub.5 represents a hydrogen atom, a saturated or unsaturated hydrocarbon group having from 1 to 4 carbon atoms, and n is an integer of from 0 to 50.The above novel phosphoric acid ester has excellent detergent performance with very low irritations to living body.A manufacturing method of the ester is also disclosed. According to the method, the ester can be prepared from inexpensive, readily available starting materials by a simple procedure in high purity and high yield.

    摘要: 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.
