Make-up compound for coloring keratin fibers and method for coloring hairs with the same

Abstract

The invention provides a method for coloring keratin fibers, wherein the fibers are treated by using i) at least one of hematoxylin and / or hematoxylin oxidation and / or brazilin and / or brazilein, ii) one or more metal salts, iii) hydrogen peroxide or one or more system for generating hydrogen peroxide, and iv) one or more carbonate or bicarbonates. The invention also provides a multi-cell device, which contains i), ii), iii) and iv). The method for coloring hairs can gain the extractives of hematoxylin and / or hematoxylin oxidation and / or brazilin and / or brazilein, especially the natural extractives, so as to better colorize, with the effects of uniform coloring, everlasting color and generating no harm to the makeup property of the keratin fibers.

Description

technical field [0001] A subject of the present invention is a process for dyeing keratin fibers by treating with i) at least hematoxylin and / or oxidized hematoxylin and / or Brazilian rosewood red and / or Brazilian rosewood, ii) at least one Metal salts, iii) at least hydrogen peroxide or at least one hydrogen peroxide generating system and iv) at least one carbonate or bicarbonate treat the fibers for dyeing. Background technique [0002] It is known to obtain "permanent" coloration using dyeing compositions containing oxidation dye precursors, commonly known as oxidation bases, such as o- or p-phenylenediamine, o- or p-aminophenol and Heterocyclic compounds. These oxidation bases are colorless or slightly colored compounds which combine with oxidative products by oxidative coupling processes to give colored compounds. It is also known that the hue obtained can be changed by combining oxidation bases with couplers or color modifiers, wherein the color modifiers are selected...
