Abstract
The invention provides a bleach composition or a dye composition for hair which, during use, includes a mixture of a first composition containing an alkali agent and a second composition containing an oxidizing agent, the bleach or dye composition containing (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 an amount of 1-70 wt. %; (B) an organic solvent having a log P of less than 0.3, in an amount of 0-8 wt. % and less than that of component (A); (C) an alkali agent in an amount of 0.1-10 wt. %; (D) an oxidizing agent in an amount of 0.1-12 wt. % as reduced to HO; and (E) water in an amount of 20-70 wt. %, or (A) in an amount of 1-70 wt. %; (B) in an amount of 0-8 wt. % and less than that of component (A); (C) in an amount of 0.1-10 wt. %; (D) in an amount of 0.1-12 wt. % as reduced to HO; (E) in an amount of 20-70 wt. %, and (F) a cationic surfactant in an amount of 0.01-10 wt. %, and has a pH of 7.5-12 after mixing of the first composition and the second composition.
