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.

An emulsion hair bleach composition prepared by combining (i) an aqueous oxidizing agent composition, and (ii) a persulfate composition comprising an organic oil having a Hildebrand solubility parameter of 5–12 (cal/cm3)1/2, and 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.
An emulsion hair bleach composition prepared by combining (i) an aqueous oxidizing agent composition, (ii) a persulfate composition containing at least one organic oil having a Hildebrand solubility parameter ranging from about 5 to 12 (cal/cm3)1/2, and (iii) a bleach oil composition in amounts sufficient to provide a mixture capable of lightening the hair in ten to thirty minutes.
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 wherein the persulfate composition contains at least one hydrophobic organic 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.
