Abstract

Composition, for stripping of keratinous fibers, comprises at least a peroxygenated salt and at least a branched non-volatile ester liquid of carboxylic acid of which solidification point is less than 4[deg] C comprising acid compound. Composition for stripping of keratinous fibers, comprises at least a peroxygenated salt and at least a branched non-volatile ester liquid of carboxylic acid of which solidification point is less than 4[deg] C comprising acid compound of formula (R 1-CO-O-R 2). R 1, R 21-30C hydrocarbon, optionally substituted by oxygen and / or carbonyl group or hydroxy group. Independent claims are included for: (1) a process for stripping comprising applying the composition in the form of an anhydrous paste, to the keratinous fibers, in the presence of an aqueous composition comprising hydrogen peroxide; and (2) a device with several compartments comprising at least two compositions conditioned separately in which the mixture led to a composition comprising hydrogen peroxide.

Description

technical field [0001] The subject of the present invention is a composition for bleaching keratin fibers, in particular human keratin fibers, such as hair, comprising at least one peroxygenated salt, and at least one non-volatile liquid branched chain of carboxylic acid Esters, whose freezing point is suitably selected below 4°C. Background technique [0002] The bleaching of human keratin fibers, and more particularly of hair, occurs by oxidation of the pigment "melanin", leading to a partial or complete breakdown and elimination of this pigment. [0003] For bleaching hair, bleaching powders comprising peroxidic reactants, such as ammonium or alkali metal persulfates, perborates and percarbonates, are utilized which are mixed with aqueous solutions of hydrogen peroxide compositions at the time of use. [0004] Since peroxides and hydrogen peroxide are relatively stable in acidic media, it is often necessary to activate them at alkaline pH for proper oxygen formation. Ba...
