COMPOSITION FOR OXIDATION DYEING OF THE KERATIN FIBER CONTAINING p-AMINOPHENOL, DIPROPYLENE GLYCOL AND ADDITIONAL DYE PRECURSOR

摘要

PROBLEM TO BE SOLVED: To provide a novel composition for oxidation dyeing of keratin fibers having no defects of conventional technologies.;SOLUTION: The composition for oxidation dyeing of keratin fibers, in particular human keratin fibers such as hair is intended to be mixed at the time of use with an oxidizing agent and includes: (A) one or more oxidation bases chosen from p-aminophenols and the corresponding addition salts thereof in an amount of greater than or equal to 1.5 wt.% of the total weight of the composition before mixing with an oxidizing agent, (B) one or more additional dye precursors different from the oxidation base defined in (A), (C) dipropylene glycol in an amount of greater than or equal to 3.5 wt.% of the total weight of the composition before mixing with an oxidizing agent. The composition is produced without difficulty.;COPYRIGHT: (C)2010,JPO&INPIT
