Abstract

Abstract Alkaline built detergent bleach compositions are disclosed comprising a surface-active agent; a peroxide compound bleach; a manganese compound which delivers manganese (II) ions in aqueous solution (e.g. manganous sulphate or manganous chloride); and a builder mixture comprising a water-insoluble aluminosilicate ion-exchange material and an alkalimetal orthophosphate and/or an alkalimetal silicate. The composition is particularly effective for washing fabrics at lower temperatures, e.g. from 20 DEG to 60 DEG C., but is also usable at higher temperatures.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 94 words
A build detergent bleach composition comprising from 2 to 50% by weight of a surface-active agent selected from the group consisting of organic anionic, nonionic, amphoteric and zwitterionic detergents and mixtures thereof; 4-50% by weight of a peroxide compound bleach; 10-50% by weight of a water-insoluble aluminosilicate cation-exchange material; 3-50% by weight of an alkali-metal orthophosphate; 0-20% by weight of an alkalimetal silicate; and a manganese compound which delivers manganese(II) ions in aqueous solution, in an amount of from 0.005 to 2.5% by weight as manganese (II) metal based on the total detergent composition.
Claim 2
Dependent Claim 94 words
A build detergent bleach composition comprising from 2 to 50% by weight of a surface-active agent selected from the group consisting of organic anionic, nonionic, amphoteric and zwitterionic detergents and mixtures thereof; 4-50% by weight of a peroxide compound bleach; 10-50% by weight of a water-insoluble aluminosilicate cation-exchange material; 3-50% by weight of an alkali-metal orthophosphate; 0-20% by weight of an alkalimetal silicate; and a manganese compound which delivers manganese(II) ions in aqueous solution, in an amount of from 0.005 to 2.5% by weight as manganese (II) metal based on the total detergent composition.
Claim 3
Dependent Claim 94 words
A built detergent bleach composition comprising from 2 to 50% by weight of a surface-active agent selected from the group consisting of organic anionic, nonionic, amphoteric and zwitterionic detergents and mixtures thereof; 4-50% by weight of a peroxide compound bleach; 10-50% by weight of a water-insoluble aluminosilicate cation-exchange material; 0-50% by weight of an alkali-metal orthophosphate; 1-20% by weight of an alkalimetal silicate; and a manganese compound which delivers manganese(II) ions in aqueous solution, in an amount of from 0.005 to 2.5% by weight as manganese (II) metal based on the total detergent composition.
Claim 4
Dependent Claim 94 words
A built detergent bleach composition comprising from 2 to 50% by weight of a surface-active agent selected from the group consisting of organic anionic, nonionic, amphoteric and zwitterionic detergents and mixtures thereof; 4-50% by weight of a peroxide compound bleach; 10-50% by weight of a water-insoluble aluminosilicate cation-exchange material; 0-50% by weight of an alkali-metal orthophosphate; 1-20% by weight of an alkalimetal silicate; and a manganese compound which delivers manganese(II) ions in aqueous solution, in an amount of from 0.005 to 2.5% by weight as manganese (II) metal based on the total detergent composition.
Claim 5
