Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

What is claimed:
1. A composition comprising a stable mixture of organic peroxide and antioxidant, wherein the weight ratio of organic peroxide to antioxidant is about 2.5:1 to about 10:1.
2. The composition as in claim 1 comprising a solvent in which the organic peroxide is soluble.
3. The composition as in claim 1 , wherein the organic peroxide is liquid in which antioxidant is soluble.
4. The composition as in claim 1 , wherein the organic peroxide is a solid in which antioxidant can be dispersed.
5. The composition as in claim 1 wherein the organic peroxide is benzoyl peroxide.
6. The composition as in claim 1 wherein the antioxidant is selected from the group consisting of butylated hydroxyl toluene (BHT), butylated hydroxyanisole (BHA), vitamin E acetate, ascorbyl palmitate, tetrahydrocurcuminoids, t-butyl hydroquinone, meta and para cresols, phenolics, and combinations thereof.
7. The composition according to claim 1 further comprising an aqueous phase.
8. The composition according to claim 7 wherein the aqueous phase further comprises at least one component selected from the group consisting of surfactant, humectant, suspending agent, buffer system, and combinations thereof.
9. The composition of claim 1 wherein the ratio of organic peroxide to antioxidant is about 10:1 by weight of the composition.
10. The composition of claim 1 wherein the ratio of organic peroxide to antioxidant is about 2.5:1 by weight of the composition.

n . I he 'cdm'pό'sitfoϊi "Of Claim 1 wherein the composition is a solution comprising less than 2% antioxidant, and no more than about 10% organic peroxide.

12. The composition of claim 1 wherein the composition is a solution comprising about 5% to about 10% antioxidant, and no more than about 20% organic peroxide.
13. The composition of claim 1 wherein the composition is a solution comprising a ratio of organic peroxide to antioxidant in an amount of about 10:1 by weight of the composition.
14. The composition of claim 1 wherein the composition is a solution comprising a ratio of organic peroxide to antioxidant in an amount of about 2.5:1 by weight of the composition.
15. The composition of claim 1 further comprising a thickener.
16. A method of increasing the stability of organic peroxide comprising combining an antioxidant with an organic peroxide to provide a stable peroxide composition having a weight ratio of organic peroxide to antioxidant at about 2.5:1 to about 10:1.
17. The method as in claim 16 wherein the composition containing organic peroxide is a solution of the organic peroxide in a solvent.
18. The method as in claim 16 wherein the organic peroxide is benzoyl peroxide.
19. The method as in claim 18 further comprising the step of formulating a product suitable for topical application to the skin containing the stable peroxide composition.

20. A'meinod cOmprising*
combining an antioxidant with benzoyl peroxide and at least one solvent to provide a stable peroxide solution wherein the weight ratio of benzoyl peroxide to antioxidant is about 2.5:1 to about 10:1; and
formulating a product suitable for topical application to the skin containing the stable peroxide solution.
21. The method of claim 20 further comprising adding an aqueous phase to the benzoyl peroxide solution to form an emulsion.
22. The method of claim 21 wherein the aqueous phase comprises at least one component selected from the group consisting of surfactant, humectant, suspending agent, buffer system, and combinations thereof.
23. The method of claim 22 wherein the humectant is glycerin.
24. A method of treating acne comprising applying a product prepared in accordance with the method of claim 20 to the skin of a subject afflicted with acne.
25. Use of antioxidant in the manufacture of an organic peroxide medicament for treatment of a skin condition.
26. The use in accordance with claim 25 wherein the organic peroxide is benzoyl peroxide.
