Abstract

Scouring cleanser compositions capable of yielding blue to green coloration on contact with aqueous media comprising (1) siliceous abrasive material (2) hypohalide-liberating bleaching agent (3) water soluble organic detergent and (4) a coloring agent comprising a pigmented carrier capable of undergoing color extension on contact with aqueous media.

Claims

1. A substantially white scouring cleanser composition capable of undergoing signal color change on contact with aqueous media consisting essentially of, on a weight basis,

(1) from 45 to 95% of a substantially anhydrous water insoluble abrasive material having a particle size within the range of from about 0.001 mm to about 0.4 mm and at least about 85% thereof passes through a seive having 0.074 mm openings, selected from the group consisting of silica, fedspar, pumic volcanic ash, diatomaceous earth, bentonite, calcium carbonate and talc, and mixtures thereof,

(2) from 0.1 to 50% of a bleaching agent capable of liberating hypohalide on contact with aqueous media,

(3) from 0.5 to 30% of a water-soluble organic detergent stable in the presence of said bleaching agent, and

(4) from 0.1 to 10.0% by weight of a coloring agent which is a pigmented carrier capable of undergoing color extension on contact with aqueous media, the pigment being substantially water dispersable selected from the group consisting of water dispersible animal, mineral and synthetic pigments, the particle size of said pigmented carrier being within the range of 50 to 600 microns with 95% passing through a 325 mesh screen, being substantially stable in the presence of said bleaching agent said pigment having a reflectance in the 450 to 535 mm wavelength region of the visible spectrum, the weight ratio of carrier to pigment being from about 1:

1 to about 150;

1 and wherein said carrier is selected from the group consisting of the abrasive materials defined in (1), water soluble organic detergent, water soluble builder salt, sodium bromide and sodium sulfate.

2. A composition according to claim 1 wherein said carrier is sodium sulfate.

3. A composition according to claim 1 wherein said carrier is silica.

4. A composition according to claim 1 wherein said carrier is trisodium phosphate.

5. A composition according to claim 1 wherein said carrier is sodium bicarbonate.

6. A composition according to claim 1 wherein said carrier is sodium dodecyl benzene sulfonate.

7. A composition according to claim 1 wherein said carrier is a mixture of sodium bromide and silica.

8. A composition according to claim 1 wherein said carrier is sodium sulfate.

9. A composition according to claim 1 wherein said carrier is feldspar.

10. A composition according to claim 1 wherein said organic detergent is sodium dodecyl benzene sulfonate.

11. A composition according to claim 10 further containing a small amount of perfume.

12. A composition according to claim 11 wherein said siliceous abrasive is silica, said bleaching agent is trichloroisocyanuric acid, said organic detergent is sodium dodecyl benzene sulfonate, said colorant is phthalocyanine-pigmented sodium bromide and said builder salt is trisodium phosphate.

13. A composition according to claim 11 wherein said abrasive is silica, said bleaching agent is chlorinated trisodium phosphate, said organic detergent is sodium dodecyl benzene sulfonate, said colorant is phthalocyanine-pigmented sodium bromide and said builder salt is sodium bicarbonate.

14. A composition according to claim 1 wherein said carrier is sodium bromide.

15. A composition according to claim 14 wherein said bleaching agent is selected from the group consisting of N-chlorimides, N-bromimides and N-brom, N-chlorimides.

16. A composition according to claim 15 wherein said bleaching agent is selected from the group consisting of trichloroisocyanuric acid, tribromoisocyanuric acid, dichloroisocyanuric acid, dibromoisocyanuric acid, and the alkali metal salts thereof.

17. A composition according to claim 16 wherein the abrasive is silica, the carrier is sodium bromide and the pigment is a phthalocyanine.
