Abstract

Abstract PCT No. PCT/US93/06223 Sec. 371 Date Jan. 17, 1995 Sec. 102(e) Date Jan. 17, 1995 PCT Filed Jun. 30, 1993 PCT Pub. No. WO94/02580 PCT Pub. Date Feb. 3, 1994.The present invention relates to dye transfer inhibiting compositions comprising: a) a polymer selected from polyamine N-oxide containing polymers which contain units having the structure formula (I), 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 (a), (b), (c), -O-, -S-, (d); x is =0 or 1; R are aliphatic, ethoxylated aliphatic, 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 surfactant system comprising a surfactant selected from nonionic and/or anionic and/or cationic and/or ampholytic and/or zwitterionic and/or semi-polar surfactants.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 62 words
A dye transfer inhibiting detergent composition comprising a) poly(4-vinylpyridine-N-oxide) having a ratio of amine N-oxide of from about 2:3 to about 1:1,000,000; and b) a cleaning effective amount of a surfactant system comprising a surfactant selected from nonionic, anionic, cationic, ampholytic, zwitterionic, semi-polar surfactants or mixtures thereof, wherein said composition is in the form of a granular or aqueous liquid detergent composition.
Claim 2
Dependent Claim 62 words
A dye transfer inhibiting detergent composition comprising a) poly(4-vinylpyridine-N-oxide) having a ratio of amine N-oxide of from about 2:3 to about 1:1,000,000; and b) a cleaning effective amount of a surfactant system comprising a surfactant selected from nonionic, anionic, cationic, ampholytic, zwitterionic, semi-polar surfactants or mixtures thereof, wherein said composition is in the form of a granular or aqueous liquid detergent composition.
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 17 words

Claim 6
Dependent Claim 27 words
A dye transfer inhibiting composition according to claim 4 further comprising a surfactant selected from an anionic surfactant or a cationic or amphoteric surfactant or mixtures thereof.
Claim 7
Dependent Claim 24 words
A dye transfer inhibiting composition according to claim 1 which is a detergent additive, in the form of a non-dusting granule or a liquid.
Claim 8
Dependent Claim 39 words
A detergent composition which comprises a dye transfer inhibiting composition according to claim 6 further comprising builders, chelants, bleaching agents, suds suppressor, soil release agents, antiredeposition agents, optical brighteners, abrasives, bactericides, tarnish inhibitors, coloring agents, perfumes, or mixtures thereof.
Claim 9
Dependent Claim 39 words
A detergent composition which comprises a dye transfer inhibiting composition according to claim 1 further comprising builders, chelants, bleaching agents, suds suppressors, soil release agents, antiredeposition agents, optical brighteners, abrasives, bactericides, tarnish inhibitors, coloring agents, perfumes, or mixtures thereof.
