Abstract

An aqueous composition comprising a hypochlorite source in an effective oxidizing concentration and a colorant system containing at least one pigment selected from the group consisting of cobalt aluminate and cobalt chromite.

Claims

1. A composition comprising an aqueous vehicle having incorporated therein an effective oxidizing amount of a hypochlorite ion and a colorant system containing one or more pigments selected from the group consisting of cobalt aluminate and cobalt chromite, said pigments not having a coating and being present in sufficient concentration to impart color to said composition.

2. The composition of claim 1 wherein the source hypochlorite ion is an alkali metal hypochlorite.

3. The composition of claim 2 wherein said pigment is present in said composition at a concentration in the range of from about 0.001% to about 0.5% by weight based on the total weight of said composition.

4. The composition of claim 1 wherein said pigment is cobalt aluminate.

5. The composition of claim 4 wherein the source of hypochlorite ion is an alkali metal hypochlorite.

6. The composition of ..claim 5 wherein the cobalt aluminate is present in said composition at a concentration in the range of from about 0.001% to about 0.5% by weight based on the total weight of the composition.

7. The composition of claim 6 wherein the concentration of said cobalt aluminate is in the range of from about 0.01% to about 0.1% by weight based on the total weight of the composition.

8. The composition of claim 6 wherein said composition is a thickened hypochlorite composition.

9. The composition of claim 6 having a viscosity in the range of from about 50 cps. to about 5,000 cps.

10. The composition of claim 6 in which the viscosity is in the range of from about 100 cps. to about 610 cps.

11. The composition of claim 6 wherein said colorant system also comprises a second pigment.

12. The composition of claim 11 wherein said second pigment is titanium dioxide.

13. The composition of claim 8 wherein the hypochlorite is thickened with a combination of anionic surfactants consisting essentially of (a) at least one alkali metal salt of an N-alkyl, N-fatty acyl amino acid;

and (b) at least one alkali metal salt of an alkyl sulfate.

14. The composition of claim 10 including a stabilizing amount of an alkali metal hydroxide.

15. The composition of claim 13 wherein the combination of surfactants also includes at least one alkali metal salt of an ethoxylated aliphatic alcohol.

16. A composition of claim 15 including a stabilizing amount of an alkali metal hydroxide.

17. The composition of claims 3, 6, 13 or 16 wherein said hypochlorite is present in said composition in the range of from about 0.5% to about 10% by weight, based on the total weight of the composition.

18. The composition of claim 4 in the form of an aqueous cleansing composition, wherein

(1) said cobalt aluminate is present in the composition at a concentration of about 0.01% to about 0.1% by weight based on the total weight of the composition;

(2) said hypochlorite is present at a concentration in the range of from about 1% to about 7% by weight based on the total weight of said composition;

(3) said composition is thickened by an anionic surfactant system containing on a weight basis, based on the total weight of said composition;

i. from about 1% to about 5% sodium lauryl sulfate,

ii. from about 0.1% to about 1.5% sodium lauroyl sarcosinate, and

iii. from about 0.1% to about 1.5% sodium lauryl ether sulfate;

said composition having a viscosity in the range of from about 100 to about 610 cps.

19. The composition of claim 18 containing as a stabilizing agent from about 0.2 to about 1.5% by weight alkali metal hydroxide based on the total weight of the composition.

20. The composition of claim 18 also including from about 0.01% to about 0.1% by weight of titanium dioxide based on the total weight of the composition.

21. A process for cleaning a surface which comprises applying to said surface a composition of claim 1.
