    • 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.
    • 由下列通式(I)表示的新型磷酸酯其中R 1表示具有1至36个碳原子的直链或支链烷基或烯基,或被具有1个直链或支链烷基取代的苯基 至15个碳原子,R 2表示具有2至3个碳原子的亚烷基,R 3,R 4和R 5各自表示氢原子或具有1至36个碳原子的直链或支链烷基,条件是R3,R4和R5中的任一个 具有5个或更多个碳原子,并且n为0至30的数是通过以下方式使磷酸酯与胺以高纯度和高收率反应得到的。 磷酸酯(I)的表面张力和起泡性优异,对皮肤的刺激性极低,可以用于洗涤剂组合物,化妆品组合物,乳化剂,分散剂,防静电剂等。
