Disclosed herein is an aqueous dye composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising, in a suitable dyeing medium: (a) at least one oxidizing agent, (b) at least one water-insoluble oxygenated organic non-dyeing compound, present in an amount of at least 30% by weight relative to the total weight of the dye composition, and (c) at least one oxidation dye precursor and/or at least one direct dye. Also disclosed herein is a process for dyeing human keratin fibers, for example, the hair, comprising applying such a composition to the keratin fibers.

Dye composition comprising at least one insoluble compound and processes using this composition

The present invention relates to a composition for washing and conditioning keratin fibers, comprising, in a cosmetically acceptable medium: at least one washing base comprising at least one anionic surfactant, and at least one anionic or nonionic amphiphilic diblock copolymer, comprising a hydrophilic block and a hydrophobic block, other than a diblock copolymer of ethylene oxide and of propylene oxide, a urethane block copolymer and a siloxane block copolymer, where the amphiphilic diblock copolymer has a ratio of the number of monomer units in the hydrophilic block to the number of monomer units in the hydrophobic block ranging from 7 to 24. The invention also relates to the method of using this composition for washing and conditioning keratin fibers, such as hair, and to a process for washing and conditioning keratin fibers using it.

Composition for washing and conditioning keratin fibers, comprising a particular amphiphilic diblock copolymer

A ready-to-use oxidizing composition for treating keratin materials, such as human keratin fibers, in particular the hair, comprising, in a cosmetically acceptable medium: (a) at least one oxidizing agent, (b) at least 30% by weight of at least one water-insoluble oxygenated organic no-dyeing particular compound relative to the total weight of the said composition, and (c) at least 20% by weight of water relative to the total weight of the said composition, and to processes for bleaching, stripping, dyeing, lightening or permanently reshaping human keratin fibers and in particular the hair, and also to the use of the said composition for bleaching, stripping, dyeing, lightening and permanently reshaping human keratin fibers and in particular the hair.

Oxidizing composition comprising insoluble compounds, and processes using this composition

The present invention relates to an aqueous composition for bleaching keratin fibers, and in particular human keratin fibers such as the hair, having a viscosity of less than 2&#xd7;10poises and comprising, in a cosmetically acceptable medium, hydrogen peroxide and at least 20% by volume of suitably selected inert particles, to a bleaching process using this composition, and also to the use of this composition for bleaching keratin fibers. The composition in accordance with the invention makes it possible rapidly to obtain substantial lightening of keratin fibers, while at the same time limiting the degradation of the keratin fibers and the skin irritation.

Aqueous composition comprising hydrogen peroxide and inert particles

Disclosed herein is a composition for the non-oxidizing aqueous direct dyeing of keratin materials, for example, human keratin fibers, such as the hair, comprising, in a cosmetically acceptable medium: (a) at least one water-soluble direct dye, and (b) at least one water-insoluble non-coloring oxygenated organic compound, present in an amount of at least 30% by weight relative to the total weight of the composition. Also disclosed herein is a process for direct dyeing keratin fibers comprising applying said composition to the fibers.

Direct dye composition comprising at least one insoluble oxygenated compound, and processes using this composition

The invention relates to the use of a water-soluble or water-dispersible linear block copolymer comprising at least one hydrophulic block and at least one hydrophobic block, the hydrophilic block representing at least 30% by weight of the linear block copolymer, with the exclusion of block copolymers of ethylene oxide and propylene oxide, block copolymers containing urethane units and block copolymers containing siloxane units, to thicken or gel aqueous hair treatment compositions containing at least one polymer that is beneficial for the hair, and also to aqueous hair compositions thickened or gelled with such a block copolymer.

Aqueous hair treatment compositions, thickened with an amphiphilic linear block copolymer

Detergent and conditioning compositions comprising, in a cosmetically acceptable medium, (A) a washing base comprising at least one anionic surfactant and at least one amphoteric surfactant and (B) at least one aminated silicone having an amine number greater than or equal to 0.4 meq/g, the amphoteric surfactant/anionic surfactant ratio by weight being greater than or equal to 0.2. The use of detergent and conditioning compositions for cleaning and for caring of the hair or the skin.

Aminated silicone detergent cosmetic composition and use

A direct emulsion for bleaching keratin fibers, preferably human keratin fibers such as hair, having an inert phase containing of a nonoxygenated and nonperfluorinated liquid compound having a water-solubility at 25&#xb0; C. of less than 1% and an aqueous hydrogen peroxide solution, a bleaching method using this direct emulsion, as it is or in the form of a ready-to-use composition, and the use of this direct emulsion for bleaching keratin fibers. The direct emulsion in accordance with the invention makes it possible to rapidly obtain substantial lightening of keratin fibers while limiting the degradation of the keratin fibers and skin irritation.

Direct emulsion for bleaching hair
