Problems solved by technology

However, these powder compositions have a number of disadvantages because of their finely divided nature: they are highly volatile and therefore emit harmful dust during handling, the materials constituting these powders (persulfates or alkaline silicic acid salt) are corrosive and irritating to the eyes, respiratory pathways and mucous membranes; in addition, these powders are difficult not only to handle but also to meter (problems due to dust and flowability)
Thus problems arise regarding the stability and storage of direct dyes in the composition

Abstract

A pasty anhydrous composition for simultaneously bleaching and dyeing human keratin fibers, such as hair, comprising, in a medium that is suitable for dyeing: at least one peroxygenated salt, at least one alkaline agent, at least one inert organic liquid present in an amount ranging from 15% to 35% by weight, relative to the total weight of the composition, and at least one cationic direct dye. The cationic dye may be chosen from azo dyes, azomethine dyes, methine dyes and xanthene dyes. A ready-to-use pasty anhydrous composition for simultaneously bleaching and dyeing human keratin fibers. A process of simultaneous bleaching and dyeing, and a device with compartments, or 'kits', comprising the described composition.

Description

technical field [0001] The present invention relates to a paste-like anhydrous composition for simultaneously bleaching and dyeing human keratin fibers, especially hair, comprising at least one peroxide salt, at least one alkaline agent, at least one inert organic liquid and At least one cationic direct dye, the invention also relates to a method for simultaneous bleaching and dyeing. Background technique [0002] In the field of hair dyeing, it can be divided into two dyeing methods. The first is permanent dyeing or oxidation dyeing using oxidation dyes capable of exhibiting their dyeing properties in the presence of oxidizing agents. The second is semi-permanent or temporary coloring or direct coloring, which uses dyes capable of imparting a more or less pronounced color change to natural-colored hair that can withstand several shampooings. These dyes are known as direct dyes; they can be used with or without oxidizing agents. When there is an oxidizing agent, the dyein...
