Oxidizing composition and uses for dyeing, for permanently setting or bleaching keratin fibres

The invention relates to a ready-to-use composition for the oxidation dyeing of keratin fibers, and in particular human keratin fibers such as the hair, comprising, in a medium which is suitable for dyeing, at least one oxidation base, at least one cationic direct dye and at least one enzyme of 2-electron oxidoreductase type in the presence of at least one donor for the said enzyme, and to the dyeing process using this composition.

A cosmetic composition for the first stage of an operation for the permanent reshaping of keratinous material, in particular the hair, which consists in reducing the disulphide bonds of keratin, characterized in that it comprises at least one active agent suitable for the reduction of the disulphide bonds of keratin, at least one basifying agent chosen from ornithine, a salt of ornithine, lysine, a salt of lysine, arginine, and a salt of arginine, and at least one cationic polymer containing primary, secondary or tertiary amine groups or quaternary ammonium groups in the main chain. A process for the treatment of keratinous material, in particular the hair, for the purpose of obtaining a permanent reshaping of the latter, in particular in the form of permanent-waved hair, the said process being characterized in that it includes the following steps: (i) a composition as defined above is applied to the keratinous material to be treated, the means (rollers) necessary for placing the keratinous material under mechanical tension being implemented before, during or after the said application, (ii) the keratinous material thus treated is then rinsed, (iii) an oxidizing composition is applied to the keratinous material thus rinsed, the treated keratinous material being separated from the means for placing under tension used in step (i) before or after the said application of the oxidizing composition, (iv) and, lastly, the keratinous material is rinsed again.

Reducing composition comprising a basic amino acid and a cationic polymer

The invention relates to a hair composition containing, in a cosmetically acceptable medium, a structuring agent insoluble in this medium and formed of solid particles, which imparts a deformable solid appearance to the composition in which the medium is contained, this agent being capable of being removed from the hair using a diluent. This composition may be a shampoo, a conditioner, a composition for dyeing or bleaching keratin fibers or alternatively a composition for permanent-waving or straightening keratin fibers.

Solid hair composition containing a particular structuring agent

The invention relates to a hair-removing composition containing, in a cosmetically acceptable medium, a structuring agent insoluble in this medium and formed of solid particles, which imparts a deformable solid appearance to the composition in which the medium is contained, this agent being capable of being removed from the skin using a diluent. These particles are, in particular, expanded copolymer particles of acrylonitrile and an acrylic and/or styrene and/or vinylidene chloride monomer.
