Phosphoric Acid Esters Containing Phosphorus Atoms Bridged By Diol Units

摘要

Phosphoric esters comprise A) one or more structural units derived from substances of component a), the substances of component a) being selected from orthophosphoric acid and one or more of its derivatives, B) one or more structural units derived from substances of component b), the substances of component b) being selected from one or more compounds of formula (I) R2—O—(CH2CH2O)u(C3H6O)v(DO)w—H  (I) and C) one or more structural units derived from substances of component c), the substances of component c) being selected from one or more diols of formula (II) HO—(CH2CH2O)a(C3H6O)b(DO)c—H  (II) where the sum total a+b+c is≧1 and the phosphoric ester contains 2 or more phosphorus atoms per molecule which are bridged via a structural unit derived from the compounds of formula (II). The phosphoric esters of the invention are very useful in the manufacture of cosmetic, pharmaceutical and dermatological compositions.
