Linear polydimethylsiloxane-polyether copolymers with amino and/or quaternary ammonium groups and use thereof
First Claim
1. A household care composition comprising a linear polydimethylsiloxane-polyether copolymers with amino and/or quaternary ammonium groups, obtainable by the reaction of organopolysiloxanes functionalized with two, terminal secondary aminoalkyl groups with a chain-extended adduct bearing two, terminal glycidyl groups formed from the reaction of a diepoxide reacted with at least one amine compound.

10. A household care composition which comprises polydimethylsiloxane-polyether copolymers with amino and/or quaternary ammonium groups obtainable by a process comprising the steps of:
-
a) a diepoxide is first reacted with at least one amine compound to give a chain-extended adduct bearing a terminal glycidyl group, the molar ratio of diepoxide to amine being variable but at least greater than 1;
1 to form a an intermediate, andb) this intermediate is then reacted with a linear polysiloxane bearing two, terminal secondary amino groups, c) optionally, the nitrogen atoms can be completely or partially neutralized at any point in this process by adding acids, and d) also optionally, water or organic compounds selected from the group of polyethers, polyols, and alcohols are added as diluents, emulsifiers or modifiers;
thereby making said polydimethylsiloxane-polyether copolymers with amino and/or quaternary ammonium groups. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
