Claim 5

The composition of claim 1, further comprising in the aqueous medium from 0.0001 to 1% by weight of a metal complexing agent selected from the group consisting of tartaric acid, malic acid, sulphosalicylic acid, telluric acid, periodic acid and the alkalimetal salts of these acids.

Claim 6

The composition of claim 4, wherein the metal complexing agent is sodiumperiodate.

Claim 7

A thickened coloured aqueous alkalimetalhypochlorite composition comprising, in an aqueous medium, from 5 to 15% by weight of an alkalimetalhypochlorite, and from 0.0001 to 0.01 percent by weight of a halogenated metalphthalocyanine pigment, containing from more than 6 up to and including 16 halogen atoms, the halogen being chlorine, bromine, or mixtures thereof, the metal being selected from the group consisting of Cu, Ni, Mg, Pt, Al, Co, Pb, Ba and V, from 0.5 to 5 percent by weight as a thickening agent a mixture of (1) a hypochlorite-soluble first detergent active compound selected from the group consisting of a tertiary amine oxide having one branched or straight C 8 -C 18 alkyl chain and two short chain alkyl groups, C 8 -C 18 alkyl-substituted betaines, quaternary ammonium compounds and mixtures thereof, and (2) a second detergent active compound selected from the group consisting of an alkalimetal salt of a fully saturated C 8 -C 18 fatty acid, an alkalimetal acylsarcosinate, an alkalimetal alkyltauride, a sugar ester, an alkalimetal C 6 -C 18 alkylsulphate, an alkalimetal C 10 -C 18 alkylether sulphate containing 1-10 moles of ethylene oxide and/or propylene oxide and mixtures thereof, the weight ratio of the hypochlorite-soluble first detergent active compound to the second detergent active compound being from 90:10 to 20:80, and the balance consisting of the aqueous medium.

Claim 8

A thickened coloured aqueous alkalimetalhypochlorite composition comprising, in an aqueous medium, from 5 to 15% by weight of an alkalimetalhypochlorite, and from 0.0001 to 0.01 percent by weight of a halogenated metalphthalocyanine pigment, containing from more than 6 up to and including 16 halogen atoms, the halogen being chlorine, bromine, or mixtures thereof, the metal being selected from the group consisting of Cu, Ni, Mg, Pt, Al, Co, Pb, Ba and V, from 0.5 to 5 percent by weight as a thickening agent a mixture of (1) a hypochlorite-soluble first detergent active compound selected from the group consisting of a tertiary amine oxide having one branched or straight C 8 -C 18 alkyl chain and two short chain alkyl groups, C 8 -C 18 alkyl-substituted betaines, quaternary ammonium compounds and mixtures thereof, and (2) a second detergent active compound selected from the group consisting of an alkalimetal salt of a fully saturated C 8 -C 18 fatty acid, an alkalimetal acylsarcosinate, an alkalimetal alkyltauride, a sugar ester, an alkalimetal C 6 -C 18 alkylsulphate, an alkalimetal C 10 -C 18 alkylether sulphate containing 1-10 moles of ethylene oxide and/or propylene oxide and mixtures thereof, the weight ratio of the hypochlorite-soluble first detergent active compound to the second detergent active compound being from 90:10 to 20:80, and the balance consisting of the aqueous medium.

Claim 9

The composition of claim 6, further comprising in the aqueous medium from 0.0001 to 1% by weight of a metal complexing agent selected from the group consisting of tartaric acid, malic acid, sulphosalicylic acid, telluric acid, periodic acid and the alkalimetal salts of these acids.
