Abstract
Abstract The invention relates to an improved detergent composition. This composition comprises at least one hydrosoluble salt of a metal selected from the group consisting of divalent iron, divalent cobalt and divalent nickel, associated with at least one hydrosoluble ligand which is a hydrogen donor and has at least two sites available for fixing to the said metal. Application to all cleaning, and preferably to laundry and dishwashing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
A detergent composition consisting essentially of soap or granular synthetic detergents, and an amount sufficient to produce superoxide ions of at least one water soluble salt of a metal selected from the group consisting of divalent iron, divalent cobalt and divalent nickel, and an amount in moles of from 1 to 10 times that of the divalent metal ions of at least one water soluble ligand which is a hydrogen donor and has at least two sites available for fixing to the said metal selected from the group consisting of --NH 2 and --COOH and mixtures thereof.
Claim 2
Dependent Claim
97 words
A detergent composition consisting essentially of soap or granular synthetic detergents, and an amount sufficient to produce superoxide ions of at least one water soluble salt of a metal selected from the group consisting of divalent iron, divalent cobalt and divalent nickel, and an amount in moles of from 1 to 10 times that of the divalent metal ions of at least one water soluble ligand which is a hydrogen donor and has at least two sites available for fixing to the said metal selected from the group consisting of --NH 2 and --COOH and mixtures thereof.
Claim 3
Dependent Claim
99 words
A detergent compositon of claim 1 free of per compounds consisting essentially of soap, an amount sufficient to produce superoxide ions of at least one water soluble salt of a metal selected from the group consisting of divalent iron, divalent nickel and divalent cobalt and an amount in moles of from 1 to 10 times that of the divalent metal ions of at least one water soluble ligand which is a hydrogen donor and has at least two sites available for fixing to the said metal selected from the group consisting of --NH 2 and --COOH and mixtures thereof.
Claim 4
Dependent Claim
26 words
A detergent composition according to claim 1 wherein said ligand is selected from the group consisting of tetraglycine fumaric acid and dihydroxyfumanic acid and salts thereof.
Claim 5
Dependent Claim
33 words
A detergent composition according to claim 1 wherein the metal salt is a Co 2+ salt and the ligand is selected from the group consisting of dihydroxyfumaric acid, tetraglycine and a mixture thereof.
Claim 6
Dependent Claim
38 words
A detergent composition according to claim 1 wherein the metal salt is a Ni 2+ salt and the ligand is selected from the group consisting of dihydroxyfumaric acid, a sodium or ammonium dihydroxyfumarate, tetraglycine and a mixture thereof.
Claim 7
Dependent Claim
34 words
A process for cleaning and removing said from any material consisting in washing said material to be cleaned in an aqueous bath of about 0.5% by weight of a detergent composition of claim 1.
Claim 8
Dependent Claim
27 words
A detergent composition of claim 1 wherein the amount of said metal and ligand is capable of releasing 10 -5 to 2×10 -3 m of superoxide ions.
Claim 9
Dependent Claim
12 words
A detergent composition of claim 1 which is free of per compounds.
Claim 10
Dependent Claim
8 words
A detergent composition of claim 8 containing soap.
