Abstract
Abstract The present invention relates to inhibiting dye transfer compositions comprising a) a polymer selected from polyamine N-oxide containing polymers which contain units having the following structure formula: ##STR1## wherein P is a polymerizable unit, whereto the N--O group can be attached to or wherein the N--O group forms part of the polymerizable unit or a combination of both. A is ##STR2## X is or 0 or 1; R are aliphatic, ethoxylated aliphatics, aromatic, heterocyclic or alicyclic groups or any combination thereof whereto the nitrogen of the N--O group can be attached or wherein the nitrogen of the N--O group form part of these groups. b) a builder.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
33 words
A dye transfer inhibiting detergent composition comprising a) poly(4-vinylpyridine-N-oxide) having a ratio of amine to amine N-oxide of from about 2:3 to about 1:1,000,000; and b) a cleaning effective amount of a builder.
Claim 2
Dependent Claim
33 words
A dye transfer inhibiting detergent composition comprising a) poly(4-vinylpyridine-N-oxide) having a ratio of amine to amine N-oxide of from about 2:3 to about 1:1,000,000; and b) a cleaning effective amount of a builder.
Claim 3
Dependent Claim
25 words
A dye transfer inhibiting composition according to claim 1 wherein the poly(4-vinylpyridine-N-oxide) polymer has an average molecular weight within the range of 500 to 1,000,000.
Claim 4
Dependent Claim
25 words
A dye transfer inhibiting composition according to claim 1 wherein the poly(4-vinylpyridine-N-oxide) is present at levels from 0.001 to 10% by weight of the composition.
Claim 5
Dependent Claim
39 words
A dye transfer inhibiting composition according to claim 1 wherein said builder is a polycarboxylate builder selected from the group consisting of ether polycarboxylates, ether hydropolycarboxylates, citrates, polyacetates, succinates, polyacrylates and their copolymers with maleic anhydrides, and mixtures thereof.
Claim 6
Dependent Claim
24 words
