Embodiment

[0123] HC Yellow 10 was dissolved in an aqueous alcoholic solution (80 / 20) at a concentration of 3.5 g%. Activator A was thus obtained.

[0124] To this solution was added a mixture of Platine Precision B powder containing 51.5% sodium, potassium and magnesium persulfate, and 4.2% sodium silicate and ammonium chloride mixed with 40 volumes of aqueous persulfate just before use. A mixture of oxidizing agents E consisting of hydrogen peroxide compositions. Bleach powder B / oxidizer E / activator A mixture is 1 / 2 / 0.5 respectively.

[0125] A portion of this mixture was applied immediately to a 1 gram strand of natural hair containing 90% white hair, and also to a 2.7 g strand of natural chestnut brown hair.

[0126] The remaining mixture was applied after 20 minutes to a 1 gram strand of natural hair containing 90% white hair and to a 2.7 g strand of natural chestnut brown hair.

[0127] In all cases the conditions are the same. The liquid ratio is equal to 10.

Abstract

The present invention relates to a composition for bleaching and simultaneously dyeing keratin fibers, comprising at least one dye chosen from meta-substituted ortho-nitroanilines and addition salts thereof, at least one peroxygenated salt and at least one alkali agent, to a method for bleaching and dyeing keratin fibers using the composition, and also to the use of the composition for bleaching and simultaneously dyeing keratin fibers. The composition in accordance with the present invention is particularly suitable for dark hair. It has improved stability over time and allows chromatic and fast dyeing to be obtained.

Description

technical field [0001] The present invention relates to a composition for the simultaneous bleaching and dyeing of keratin fibers, and in particular human keratin fibers such as hair, comprising at least one selected from the group consisting of meta-substituted o-nitroanilines and their addition salts dyes, at least one peroxygenated salt and at least one alkalizing agent. Background technique [0002] When a person wishes to completely change the color of their hair, especially when they wish to obtain a shade lighter than their original color, it is often necessary to bleach and, if desired, color the hair. There are various ways to achieve this. [0003] The first method is to use ammonia and hydrogen peroxide based color lightening products. These products may optionally contain dyes which lighten and color the hair at the same time. However, the lightening performance of these products is still limited, especially for natural and / or darkly colored base colors. [0...
