US08686033B2 Phosphoric acid esters containing phosphorus atoms bridged by diol units 失效
含有由二醇单元桥连的磷原子的磷酸酯

Phosphoric acid esters containing phosphorus atoms bridged by diol units
Abstract:
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.
Abstract(Chinese):

磷酸酯包括A）一种或多种衍生自组分a）的物质的结构单元，组分a）的物质选自正磷酸及其一种或多种衍生物，B）一种或多种衍生自组分b的物质的结构单元 ），组分b）的物质选自一种或多种式（I）R 2 -O-（CH 2 CH 2 O）u（C 3 H 6 O）v（DO）w-H（I））的化合物和C）一种或多种衍生的结构单元 从组分c）的物质中，组分c）的物质选自一种或多种式（II）的二醇HO-（CH 2 CH 2 O）a（C 3 H 6 O）b（DO）c-H（II），其中总和a + b + c为≥1，磷酸酯每分子含有2个以上的磷原子，该磷原子通过衍生自式（II）化合物的结构单元桥连。 本发明的磷酸酯在制造化妆品，药​​物和皮肤病学组合物中非常有用。
