Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for treating keratinous fibers, particularly human keratinous fibers, such as hair, with oxidation base (+)
The present invention relates to a novel method for staining with Aspergillus acetate and compositions for use in this method and apparatus.

For many years, so-called "direct" dyes, or so-called "oxidation" dyes, have been used for dyeing keratinous fibers, especially hair; "direct" dyes can themselves color keratinous fibers, and "Oxidation" dyes, after developing dyeing power in an oxidizing medium, can obtain a coloration that is resistant to several shampoo treatments, light and harsh climates.

Oxidation dyes are generally not dyes per se, but are intermediate compounds, commonly referred to as "oxidation dyes or precursors," that have little or no initial color, and generally are oxidation dyes consisting of hydrogen peroxide. It exhibits dyeing power in a basic medium, by itself according to the method of oxidative condensation of oxidative dye precursors, or with "oxidative dyes or precursors" and "one-color modifiers" or "couplers". Following the method of oxidative condensation with compounds called, the dyes are produced.

The different molecules involved, the different molecules formed by these oxidative dyes, and the possibility of coupling them make it possible to obtain a color-rich palette in terms of grays, blacks, natural hues and sparkling hues. possible.

This type of coloring is called "permanent coloring", whereas the coloring obtained with so-called "direct" dyes is called "semi-permanent coloring".

A method using pretreatment with ions in the form of soluble salts and subsequent application of an oxidative dye after an intermediate rinsing step comprises:
Already proposed in the past.

In the present invention, the method of using compositions containing a combination of oxidized bases and iodide ions may result in different but stronger results than previously obtained with traditional systems of oxidative polymerization of these bases and couplers. , it has been discovered that it is possible to obtain a hue, and this method constitutes the subject of the invention.

Further, according to the present invention, the coloring obtained thereby is
It is possible to reduce the exposure time and in this way produce much more rapid staining than is obtainable with prior art systems.
