POLYMERIC PRO-FRAGRANCE

摘要

A pro-fragrance compound obtainable by the reaction of at least one fragrance molecule comprising at least one ketone and/or aldehyde functionality, and at least one diol of formula (I) wherein R1 is a linear or branched C2-C20-alkyl, and n is a number from 4 to 1000, and, optionally, at least one diol of formula (II) wherein R2 is a linear or branched C2-C20-alkyl, optionally containing at least a functionality selected from ether, ester, amide, carbonate, carboxyl, carboxylic acid sodium salt, carboxylic acid amine salt, sulfone, sulfoxide, sulfonyl, sulfonic acid sodium salt, sulfonic acid amine salt, phosphonyl, phosphonic acid sodium salt, phosphonic acid amine salt, pyridinium, and ammonium groups, a process for the production of said pro-fragrance compound, the use of said pro-fragrance compound in detergents, cleaning, fabric treatment or cosmetic compositions, as well as detergents, cleaning, fabric treatment or cosmetic compositions comprising from 0.001 to 50% by weight of such pro-fragrance compounds.
