Abstract

This invention relates to compositions and methods for hair bleaching. In particular, the invention concerns stabilized hair bleach products that contain at least one persulfate salt, and an oil gel. The composition of the present invention forms an emulsion where the oil and salt do not separate providing a consistent and stable hair bleach formulation.

Claims

1. A stable hair bleach composition comprising an oil gel and a persulfate salt.

2. The hair bleach composition of claim 1, wherein the oil gel contains a hydrophobic and lipophilic material and a polymer/copolymer.

3. The hair bleach composition of claim 2, wherein the hydrophobic and lipophilic material is selected from the group consisting of materials are selected from mineral oil, hydrogenated polyisobutene, alkyl benzoate, isopropyl palmitate, isohexadecane, isododecane, and isononyl isononanoate.

4. The hair bleach composition of claim 2, wherein the polymer/copolymer is ethylene/propylene/styrene copolymer and butylene/ethylene/styrene copolymer.

5. The hair bleach composition of claim 1, wherein the persulfate salt is selected from the group consisting of sodium persulfate, potassium persulfate, and ammonia persulfate.

6. The hair bleach composition of claim 1, further comprising a chelating agent, a conditioner, a thickener, or silica.

7. The hair bleach composition of claim 1, wherein the concentration of the oil gel is about 5-60% by weight of the composition.

8. The hair bleach composition of claim 1, wherein the concentration of the persulfate salt is about 25-90% by weight of the composition.

21. A method for bleaching hair comprising the step of applying the composition of claim 1 to the hair.

22. The method of claim 21, where in the composition is mixed with hydrogen peroxide before the application to the hair.

9. A method for making a stable hair bleach composition comprising the steps of

a) providing an oil gel;

and

b) suspending a persulfate salt in the oil gel.

10. The method of claim 9, wherein the wherein the oil gel contains a hydrophobic and lipophilic material and a polymer/copolymer.

11. The method of claim 10, wherein the hydrophobic and lipophilic material is selected from the group consisting of materials are selected from mineral oil, hydrogenated polyisobutene, alkyl benzoate, isopropyl palmitate, isohexadecane, isododecane, and isononyl isononanoate.

12. The method of claim 10, wherein the polymer/copolymer is ethylene/propylene/styrene copolymer and butylene/ethylene/styrene copolymer.

13. The method of claim 9, wherein the persulfate salt is selected from the group consisting of sodium persulfate, potassium persulfate, and ammonia persulfate.

14. The method of claim 9, further comprising a step of suspending a chelating agent, a conditioner, a thickener, or silica in the oil gel.

15. The method of claim 9, wherein the concentration of the oil gel is about 5 to 60% by weight.

16. The method of claim 9, wherein the concentration of the persulfate salt is about 25 to 90% by weight.

19. The method of claim 10, wherein the polymer/copolymer is ethylene/propylene/styrene copolymer and butylene/ethylene/styrene copolymer.

20. The method of claim 9, wherein the persulfate salt is selected from the group consisting of sodium persulfate, potassium persulfate, and ammonia persulfate.

17. A method for preventing separation of a composition containing a hydrophobic and lipophilic material and a persulfate salt, said method comprising the step of suspending the hydrophobic and lipophilic material and the persulfate salt in a polymer/copolymer gel.

18. The method of claim 17, wherein the wherein the hydrophobic and lipophilic material is selected from the group consisting of materials are selected from mineral oil, hydrogenated polyisobutene, alkyl benzoate, isopropyl palmitate, isohexadecane, isododecane, and isononyl isononanoate.
