Abstract
Novel phosphoric esters represented by the following general formula (I) ##STR1## wherein R.sub.1 represents a linear or branched alkyl or alkenyl group having 1 to 36 carbon atoms, or a phenyl group substituted with a linear or branched alkyl group having 1 to 15 carbon atoms, R.sub.2 represents an alkylene group having 2 to 3 carbon atoms, R.sub.3, R.sub.4 and R.sub.5 individually represent a hydrogen atom or a linear or branched alkyl group having 1 to 36 carbon atoms providing that any one of R.sub.3, R.sub.4 and R.sub.5 has 5 or more carbon atoms, and n is a number from 0 to 30 are obtained by reacting phosphoric esters of the following formula ##STR2## with amines at a high purity and in a high yield. The phosphoric esters (I) are excellent in the surface tension and foaming property, and give extremely low stimulus to the skin, so that they can be utilized in detergent compositions, cosmetic compositions, emulsifiers, dispersants, anti-static agents and the like.
