Abstract

The present invention relates generally to detergent compositions and, more specifically, to detergent compositions containing salts of polyetheramines and polymeric acid, particularly salts of polyetheramines and polycarboxylic acid, which are suitable for removal of stains from soiled materials.

First claim

What is claimed is:

1. A detergent composition comprising:
from about 1% to about 70% by weight of a surfactant selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, amphoteric surfactants, and mixtures thereof; and
from about 0.1% to about 10% of a salt of a polymeric acid and a polyetheramine of Formula (I):

wherein R 3 is an ethyl group, R 1 , R 2 , R 5 , and R 6 are each H, and R 4 is a butyl group,
wherein each of A 1 -A 6 is independently selected from linear or branched propylene or linear or branched butylene, the sum of x+y is in the range of from 2 to about 200, x≧1 and y≧1, and the sum of x 1 +y 1 is in the range of from 2 to about 200, x 1 ≧1 and y 1 ≧1.

2. The detergent composition according to claim 1 , wherein each of A 1 -A 6 is linear or branched propylene.

3. The detergent composition of claim 1 , wherein the polymeric acid is a homopolymer of a carboxylic acid or a copolymer of acrylic acid and maleic acid.

4. The detergent composition of claim 1 , wherein the polymeric acid is an alkoxylated homopolymer of a carboxylic acid or alkoxylated copolymer of acrylic acid and maleic acid.

5. The detergent composition of claim 1 , wherein the polymeric acid is a sulfonated homopolymer of a carboxylic acid or sulfonated copolymer of acrylic acid and maleic acid.

6. The detergent composition of claim 1 wherein the polymeric acid is a carboxylic acid terpolymer including a structural unit derived from an ether-bond-containing monomer and a structural unit derived from a sulfonic-acid-group-containing monomer.

7. The detergent composition of claim 1 , wherein the polymeric acid is a polyacrylic acid with a molecular weight Mw of from about 1000 g/mol to about 1.000,000 g/mol.

8. The detergent composition of claim 1 , wherein the polymeric acid is a copolymer of acrylic acid and maleic acid with a molecular weight of from about 1000 g/mol to about 1,000,000 g/mol.

9. The detergent composition of claim 1 further comprising from about 0.001% to about 1% by weight of enzyme, wherein said enzyme is selected from lipase, amylase, protease, mannanase, or combinations thereof.

10. A method of pretreating or treating a soiled fabric comprising contacting the soiled fabric with the detergent composition according to claim 1 .
