Abstract

A process for the lightening dyeing of keratin materials using an anhydrous dyeing composition comprising an alkaline agent and an oxidizing composition. Provided is a process for dyeing keratin materials, comprising applying an anhydrous composition (A) comprising one or more fatty substances (greater than 20 wt.%), one or more surfactants, one or more alkaline agents, and one or more colored species or dyes (oxidation dyes or direct dyes), and a composition (B) comprising one or more oxidizing agents; provided that when the composition only comprises one or more direct dyes as colored species or dyes, then the fat content is 40-80 wt.% of (A). An independent claim is included for multi-compartment device comprising (A) in a first compartment, and (B) in another compartment.

Description

technical field [0001] The present invention relates to a method of lightening and coloring human keratin material, especially hair. Background technique [0002] In most cases, the method of lightening keratin materials, such as human keratin fibers, involves the use of an aqueous composition comprising at least one oxidizing agent at an alkaline pH. The effect of this oxidizing agent is to degrade the melanin of the hair, producing more or less the claimed lightening of the fibers, depending on the nature of the oxidizing agent contained. Thus, for relatively mild desalination, the oxidizing agent is usually hydrogen peroxide. When stronger desalination is required, those used are usually made from peroxygenated salts such as persulfates in hydrogen peroxide. [0003] A problem arises because the desalination process is carried out under alkaline conditions, and the most commonly used alkaline reagent is ammonia. Ammonia is particularly suitable for this type of method....
