Abstract

An emulsion hair bleach composition prepared by combining an aqueous oxidizing agent composition, a persulfate composition, and, optionally, a bleach oil composition, in amounts sufficient to provide a mixture containing an active oxygen concentration of about 3 to 5% by weight of the total mixture, a total alkalinity concentration of about 0.7-1.2 meq/gm., and 0.5-20% by weight of the total mixture of an oil having a solubility parameter of 5-12 (cal/cm³)^1/2; an emulsion hair bleach composition capable of lightening hair in 10 to 30 minutes, and a kit for use in bleaching hair.

Claims

1. An emulsion hair bleach composition prepared by combining (i) an aqueous oxidizing agent composition, (ii) a persulfate composition, and, optionally, (iii) a bleach oil composition, in amounts sufficient to provide a mixture containing:

(a) an active oxygen concentration of about 3 to 5% by weight of the total mixture,

(b) a total alkalinity concentration of about 0.7-1.2 meq/gm., and

(c) about 0.5-20% by weight of the total mixture of an oil having a Hildebrand solubility parameter of 5-12 (cal/cm³)^1/2.

2. The mixture of claim 1 wherein the active oxygen is provided by one or more of peroxide oxidizing agents or persulfates.

3. The mixture of claim 2 wherein the peroxide oxidizing agent comprises hydrogen peroxide.

4. The mixture of claim 2 wherein the persulfate comprises an alkaline earth metal persulfate, an alkali metal persulfate, an ammonium persulfate, or mixtures thereof.

5. The mixture of claim 1 wherein the active oxygen concentration is about 3.2 to 4.8% by weight of the total mixture.

6. The mixture of claim 1 wherein the total alkalinity is provided by one or more alkalizing agents.

7. The mixture of claim 6 wherein the alkalizing agents either alone or in combination have a pH ranging from about 7.5 to about 11.5.

8. The mixture of claim 7 wherein the alkalizing agent comprises one or more of an ionizable hydroxyl containing compound, amine, an inorganic salt, or mixtures thereof.

9. The mixture of claim 8 wherein the ionizable hydroxyl containing compound comprises ammonium hydroxide, sodium hydroxide, potassium hydroxide, or mixtures thereof.

10. The mixture of claim 8 wherein the amine is a primary amine.

11. The mixture of claim 10 wherein the amine is a C1-10 alkanolamine.

12. The mixture of claim 11 wherein the alkanolamine is monoethanolamine.

13. The mixture of claim 8 wherein the inorganic salt comprises an alkali metal silicate or alkaline earth metal silicate.

14. The mixture of claim 1 wherein the total alkalinity comprises a proportion of free alkalinity.

15. The mixture of claim 1 wherein the hydrophobic oil has a Hildebrand solubility parameter ranging from about 7 to about 9 (cal/cm³)^1/2.

16. The mixture of claim 1 wherein the hydrophobic oil comprises coconut oil, mineral oil, isopropyl myristate, linseed oil, octyl palmitate, or mixtures thereof.

17. The mixture of claim 1 which is prepared by combining an aqueous oxidizing agent composition, a persulfate composition, and a bleach oil composition.

18. The mixture of claim 17 wherein the aqueous oxidizing agent composition comprises a solution or emulsion of hydrogen peroxide.

19. The mixture of claim 17 wherein the aqueous oxidizing agent composition is an emulsion.

20. The mixture of claim 18 wherein the aqueous oxidizing agent composition comprises, by weight of the total composition:

about 1-30% hydrogen peroxide,

about 50-99% water, and

about 0.1-30% by weight of the total composition of an oily phase.

21. The mixture of claim 20 wherein the oily phase comprises silicone.

22. The mixture of claim 18 wherein the persulfate composition comprises, by weight of the total persulfate composition:

about 15-65% of one or more inorganic persulfates,

about 0.1-5% of one or more inorganic salts, and

about 5-60% of one or more particulate fillers.

23. The composition of claim 22 which is in the powdered form.

24. The composition of claim 22 which is in the cream or paste form.

25. The composition of claim 24 further comprising an oil which is a hydrophobic oil, a lipophilic ingredient or mixtures thereof.

26. The mixture of claim 17 wherein the bleach oil composition comprises, by weight of the total bleach oil composition:

about 1-75% water,

about 0.1-50% hydrophobic oil, and

about 0.1-50% of one more more alkalizing agents.

27. The composition of claim 26 wherein the hydrophobic oil comprises coconut oil, mineral oil, isopropyl myristate, or mixtures thereof.

30. The kit of claim 1 wherein the aqueous oxidizing agent composition comprises about 20-80% by weight of the total mixture, the persulfate composition comprises about 5-40% by weight of the total mixture, and the bleach oil composition comprises about 10-30% by weight of the total mixture.

28. An emulsion hair bleach composition prepared by combining (i) an aqueous oxidizing agent composition, (ii) a persulfate composition, and (iii) a bleach oil composition containing at least one hydrophobic oil having a Hildebrand solubility parameter ranging from about 5 to 12 (cal/cm³)^1/2;

in amounts sufficient to provide a mixture capable of lightening the hair in ten to thirty minutes.

29. A kit for use in bleaching hair comprising three separate components, wherein the first component is an aqueous oxidizing agent composition, the second component is a persulfate composition, and the third composition is a bleach oil composition containing at least one hydrophobic oil having a Hildebrand solubility parameter ranging from about 5 to 12 (cal/cm³)^1/2;

wherein when said three components are mixed they provide a mixture that lightens hair in ten to thirty minutes.
