PHOSPHORIC ACID ESTERS CONTAINING PHOSPHORUS ATOMS BRIDGED BY POLYOL UNITS

摘要

The invention relates to phosphoric acid esters containing A) at least one structural unit derived from substances of constituent a), the substances of constituent a) being selected from orthophosphoric acid and at least one of the derivatives thereof; B) at least one structural unit derived from substances of constituent b), the substances of constituent b) being selected from at least one compound of formula (I) R2-O-(CH2CH2O)U(C3H6O)V(DO)w-H; and C) at least one structural unit derived from substances of constituent c), the substances of constituent c) being selected from at least one polyol which has more than 2 OH groups and can also carry at least one alkoxylate group. The alkoxylate groups are respectively formed from at least one unit selected from CH2CH2O, C3H6O and C4H8O units that can respectively be arranged in a block or in a statistically distributed manner inside the alkoxylate groups. The phosphoric acid esters contain at least two phosphorus atoms per molecule, said phosphorus atoms being bridged by a structural unit derived from the polyols having more than two OH groups or from the polyols having more than two OH groups and carrying at least one of the alkoxylate groups. The phosphoric acid esters according to the invention can be used advantageously for producing cosmetic, pharmaceutical and dermatological compositions.
