Patent ID: 6916432

Claim:
A hair bleach or dye composition, comprising: at least two separate components of: a first aqueous alkali component containing an alkali agent (C) in an amount of 0.1-10 wt % based on the entire composition, and a second aqueous oxidation component containing an oxidizing agent (D) in an amount corresponding in effect to 0.1-12 wt % of hydrogen peroxide; the composition further comprising: (A) an organic solvent having a partition coefficient (octanol-water) (log P) at 25° C. of 0.3-6 and a molecular weight of 200 or less, in at least one of the first aqueous alkali and second aqueous oxidation components such that the total amount of component (A) ranges from 1-70 wt % of the entire composition; (B) an organic solvent having a partition coefficient (octanol-water) (log P) at 25° C. of less than 0.3, in at least one of the first aqueous alkali and second aqueous oxidation components such that the total amount of component (B) ranges from 0-8 wt % of the entire composition, but less than the amount of component (A); (E) water in an amount of 20-55 wt % of the entire composition; and a saturated or unsaturated C 12 -C 22 linear or branched monohydric alcohol (I) in at least one of the first aqueous alkali or second aqueous oxidation components in an amount ranging from 0.1-20 wt % based on the entire composition, the hair bleach composition, upon admixture of the first aqueous alkali and second aqueous oxidation components upon use, having a pH of 7.5-12.
