Abstract

Household care compositions having a linear polydimethylsiloxane-polyether copolymers with amino and/or quaternary ammonium groups, obtainable by the reaction of organopolysiloxanes functionalized with secondary aminoalkyl groups with the reaction products formed from compounds containing epoxy groups and amines, the use thereof and process for preparation thereof.

Claims

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.

2. The household care composition according to claim 1, wherein the household care composition is selected from the group consisting of liquid laundry detergent compositions, solid laundry detergent compositions, hard surface cleaning compositions, liquid hand dishwashing compositions, solid automatic dishwashing compositions, liquid automatic dishwashing, tab/unit dose form automatic dishwashing compositions, tab/unit dose form laundry care compositions, dryer bar compositions, dryer sheet coat mix compositions, fabric spray compositions, stain treatment composition, laundry detergent booster compositions, single rinse fabric softener compositions, and single rinse fabric enhancer compositions.

3. The household care composition according to claim 2, wherein the household care composition further comprises from about 0.1% to about 50% by weight of a surfactant selected from the group consisting of anionic, cationic, amphoteric, nonionic surfactants, and combinations thereof.

4. The household care composition of claim 3, wherein the household care composition further comprises an adjunct selected from the group consisting of delivery enhancing agents, fluorescent whitening agents, enzymes, rheology modifiers, builders, and mixtures thereof.

5. The household care composition of claim 4, wherein the household care composition further comprises a delivery enhancing agent.

6. The household care composition according to claim 1, wherein the household care composition comprises from about 0.01% to about 15% by weight of the composition of said linear polydimethylsiloxane-polyether copolymers.

7. The household care composition according to claim 1, having copolymers of formula (4)

H-A-[(B—

C)_x—

B-A]_y-H 

 

Formula (4)

where A is a siloxane fragment from the structure of the aminosiloxane of the formula (3)

8. The household care composition of claim 7 wherein said copolymers of the formula (4) have been neutralized with acids and/or quaternized with alkylating agents and bear ammonium groups.

9. The household care composition according to claim 7 further comprising at least one additional component selected from the group consisting of emollients, emulsifiers and surfactants, thickeners/viscosity regulators/stabilizers, UV light protection filters, antioxidants, hydrotropes or polyols, solids and fillers, film formers, pearlescent additives, insect repellents, preservatives, conditioners, perfumes, dyes, care additives, and solvents.

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, and

b) 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.

11. The household care composition according to claim 10, wherein the diepoxides used are compounds of the formula (1)

12. The household care composition according to claim 11, wherein Y is a divalent polyether radical of the

—

(CH₂—

CHR²—

O)_m—

CH₂—

CHR²—

type, where m is an integer from 0 to 50 and R² is hydrogen or an alkyl group having 1-4 carbon atoms.

13. The household care composition according to claim 10, wherein the amine compounds used in process step (a) are di-secondary amines of the formula (2)

14. The household care composition according to claim 13, wherein the compound of the formula (2) is a cyclic amine where p is 1 or a linear diamine, or the two nitrogen atoms are constituents of a heterocyclic fragment.

15. The household care composition according to claim 14, wherein the compound of the formula (2) used is piperazine or N,N′

-dimethylhexamethylene-1,6-diamine or N,N′

-dimethyltetramethylene-1,4-diamine.

16. The household care composition according to claim 10 wherein the compounds used in reaction step (b) are linear polysiloxanes which have terminal secondary amino groups and are of the formula (3)

17. The household care composition according to claim 10, wherein an acid or an alkylating reagent is added in process step (c).
