Composition and method for cream bleach product
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.
1. A stable hair bleach composition comprising about 5-60% by weight of the composition of an oil gel and about 25-90% by weight of the composition of a persulfate salt, wherein the oil gel contains mineral oil, ethylene/propylene/styrene copolymer, and butylene/ethylene/styrene copolymer.
2. 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.
3. The hair bleach composition of claim 1 , further comprising a chelating agent, a conditioner, a thickener, or silica.
4. A method for bleaching hair comprising the step of applying the composition of claim 1 to the hair.
5. The method of claim 4 , where in the composition is mixed with hydrogen peroxide before the application to the hair.
6. A method for making a stable hair bleach composition comprising the steps of a) providing an oil gel, wherein the oil gel contains mineral oil, ethylene/propylene/styrene copolymer, and butylene/ethylene/styrene copolymer; and b) suspending a persulfate salt in the oil gel, wherein the concentration of the persulfate salt is about 25-90% by weight of the composition and the concentration of the oil gel is about 5-60% by weight of the composition.
7. The method of claim 6 , wherein the persulfate salt is selected from the group consisting of sodium persulfate, potassium persulfate, and ammonia persulfate.
8. The method of claim 6 , further comprising a step of suspending a chelating agent, a conditioner, a thickener, or silica in the oil gel.
9. The method claim 6 , wherein the persulfate salt is selected from the group consisting of sodium persulfate, potassium persulfate, and ammonia persulfate.
10. 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, wherein the hydrophobic and lipophilic material is mineral oil and the polymer/copolymer gel is ethylene/propylene/styrene copolymer and butylene/ethylene/styrene copolymer, wherein the concentration of the persulfate salt is about 25-90% by weight of the composition and the concentration of the oil gel is about 5-60% by weight of the composition.
11. The method of claim 10 , wherein the persulfate salt is selected from the group consisting of sodium persulfate, potassium persulfate, and ammonia persulfate.
