Abstract
Abstract The invention provides an odor neutralizing composition comprising: (a) a complexing agent selected from a polymer of the formula (1) ##STR1## in which R is a substituted or unsubstituted alkylene group having up to 12 carbon atoms in the unsubstituted chain. (b) a carrier capable of assisting wetting of odor forming compositions; and (c) a cationic moiety; said moiety being part of a chemically independent compound, or chemically associated with a complexing agent or the carrier.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
An odor neutralizing composition comprising (a) a complexing agent selected from a polymer of the formula (1) ##STR5## in which R is a substituted or unsubstituted alkylene group having up to 12 carbon atoms in the unsubstituted chain; (b) a carrier capable of assisting wetting of odor forming compositions; (c) a cationic moiety; said moiety being part of a chemically independent compound, or chemically associated with a complexing agent or the carrier, and (d) an auxiliary complexing agent selected from a transition metal ion which is capable of oxidation.
Claim 2
Dependent Claim
89 words
An odor neutralizing composition comprising (a) a complexing agent selected from a polymer of the formula (1) ##STR5## in which R is a substituted or unsubstituted alkylene group having up to 12 carbon atoms in the unsubstituted chain; (b) a carrier capable of assisting wetting of odor forming compositions; (c) a cationic moiety; said moiety being part of a chemically independent compound, or chemically associated with a complexing agent or the carrier, and (d) an auxiliary complexing agent selected from a transition metal ion which is capable of oxidation.
Claim 3
Dependent Claim
16 words
A composition according to claim 1 wherein the cationic moiety is associated with the complexing agent.
Claim 4
Dependent Claim
24 words
A composition according to claim 1 wherein the ion is derived from the reaction of an organic acid with a divalent transition metal salt.
Claim 5
Dependent Claim
21 words
A composition according to claim 1 comprising an auxiliary complexing agent selected from a quaternary ammonium salt and an organic acid.
Claim 6
Dependent Claim
32 words
A composition according to claim 4 wherein the quaternary ammonium salt is a substituted or unsubstituted aromatic quaternary ammonium salt, and the organic acid is selected from citric, ascorbic or acetic acids.
Claim 7
Dependent Claim
56 words
A deodorising composition comprising a complexing agent selected from one or more of an organic acid and a transition metal ion capable of oxidation; a carrier capable of assisting wetting of odor forming compositions, and a cationic moiety; said moiety being part of a chemically independent compound, or chemically associated with the carrier or complexing agent.
Claim 8
Dependent Claim
56 words
A deodorising composition comprising a complexing agent selected from one or more of an organic acid and a transition metal ion capable of oxidation; a carrier capable of assisting wetting of odor forming compositions, and a cationic moiety; said moiety being part of a chemically independent compound, or chemically associated with the carrier or complexing agent.
Claim 9
Dependent Claim
46 words
A composition according to claim 6 wherein the complexing agent is selected from a quaternary ammonium compound; and in that the transition metal ion is divalent and is derived from the product of a reaction between a source of transition metal ions and an organic acid.
Claim 10
Dependent Claim
48 words
A composition according to claim 7 wherein the quaternary ammonium compound is dimethylbenzyl ammonium chloride, the complexing agent is the reaction product of citric ascorbic or acetic acid and a reactive salt or ion copper or gold, and in that the carrier is a non-ionic or amphoteric surfactant.
Claim 11
Dependent Claim
10 words
An article impregnated with a composition according to claim 1.
Claim 12
Dependent Claim
18 words
