International ClassC08G 077/06AbstractThe present invention relates to a series of novel silicone ester quaternary polymers which are substantive to fiber and provide outstanding softening properties to various fibers, hair and skin. The compounds of the present invention are prepared by the esterification of a terminal hydroxyl group which is present on a silicone polymer with monochloroacetic acid, and in a subsequent step, reacting the chloro ester so produced with a tertiary amine to produce the desired quaternary compound.Field of SearchOrganic Si-free reactant is a carboxylic acid or derivativeMaterial contains a Group VIII metal atom Silicon reactant contains a silicon-to-hydrogen bond Organic Si-free reactant is a nitrogen-containing compound Silicon compound containing coating Plural hetero atoms in the hetero ring The carbonyl is part of a -COO- group |
