Abstract:
The present invention relates to the field of dyeing keratin fibres and more particularly to the field of hair dyeing. The present invention relates to a process for the oxidation dyeing of keratin fibres, in particular human keratin fibres such as the hair, which consists in using on the said fibres i) a substrate comprising on its surface one or more oxidation dyes, and ii) an aqueous composition comprising one or more oxidizing agents. The present invention also relates to a process for preparing the said substrate thus pretreated.
Abstract:
The present invention relates to a composition for dyeing keratin fibres, comprising: a) one or more liquid fatty substances; b) one or more amphoteric surfactants of formula (I) below: Ra′—C(O)—NH—CH2—(CH2)n—N(B)(B′) in which: —B represents the group —CH2—CH2—O—X′; —B′ represents the group —(CH2)zY′, with z=1 or 2; —X′ represents the group —CH2—C(O)OH, —CH2—C(O)OZ′, —CH2—CH2—C(O)OH or —CH2—CH2—C(O)OZ′, or a hydrogen atom; —Y′ represents the group —C(O)OH, —C(O)OZ″, —CH2—CH(OH)—SO3H or the group —CH2—CH(OH)—SO3—Z″; —Z′ and Z″ represent, independently of each other, a cationic counterion derived from an alkali metal or alkaline-earth metal, such as sodium, an ammonium ion or an ion derived from an organic amine; —Ra′, represents a C10-C30 alkyl or alkenyl group derived from an acid Ra′—C(O)OH, which is preferably present in copra oil or in hydrolysed linseed oil, an alkyl group, especially a C17 group and its iso form, or an unsaturated C17 group and—n represents an integer ranging from 1 to 10 and preferably from 1 to 5,—or quaternized forms thereof; c) one or more sulfate or sulfonate surfactants; d) one or more oxidation dye precursors. The present invention also relates to a process using this composition and to a multicompartment device that is suitable for performing the said process.

Abstract:
The subject of the present invention is a composition for dyeing human keratin fibres, such as the hair, which is free of chemical oxidizing agent other than atmospheric oxygen and which comprises: (a) at least one oxidation dye precursor; (b) at least one liquid fatty substance; (c) at least one non-ionic guar gum; (d) at least one anionic surfactant chosen from C6-C40 alkyl sulfates or non-salified forms thereof; (e) at least one non-ionic alkylpolyglycoside surfactant. It also relates to a process for dyeing human keratin fibres, in which this composition applied in the presence of at least one oxidizing agent other than atmospheric oxygen.
