The present invention relates to a process for treating keratin fibers such as the hair using a packaging article comprising i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibres, preferably water-soluble fibres; ii) at least one anhydrous oxidizing composition, preferably in paste or powder form, comprising at least one anhydrous chemical oxidizing agent, preferably in paste or powder form; it being understood that the oxidizing composition is in one of the cavities defined by the envelope i).

Process for treating keratin fibers using a packaging article comprising an envelope and an anhydrous composition comprising an oxidizing agent

The invention relates to a process for dyeing keratin fibers by treating said fibers with i) at least one aromatic compound comprising a hydrocarbon-based polycycle comprising at least 10 carbon atoms, at least one of the rings of which is aromatic, ii) at least one indol(in)e compound; optionally iii) at least one metal salt, iv) at least hydrogen peroxide or at least one hydrogen peroxide-generating system and v) at least one basifying agent; to a dye composition comprising ingredients i) and ii), and optionally iii) to v) as defined previously and to a kit comprising ingredients i) to v) as defined previously. This hair dyeing process makes it possible to obtain better colorings which are more uniform, chromatic and long-lasting and which do not impair the cosmetic properties of the keratin fibers, and prevents changing of the color associated with the presence of indol(in)e derivatives.

Hair dyeing process using a composition comprising at least one indol(in)e compound and a polycyclic aromatic compound containing at least ten carbon atoms

The present invention relates to a packaging article comprising: i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibres; ii) at least one anhydrous dye composition containing at least one direct dye; and iii) optionally at least one anhydrous oxidizing agent; it being understood that the dye composition ii) and the anhydrous oxidizing agent iii), when it is present, are in one of the cavities defined by the envelope i). Another subject of the invention is the use of the said article for dyeing keratin fibres and a process for dyeing keratin fibres using the said article. The use of the packaging article makes it possible to obtain dye compositions whose consistency is pleasant on use, which are easy to apply and which make it possible to obtain powerful colouring of the hair.

Packaging article comprising an envelope and an anhydrous dye composition comprising a direct dye, use of the same and process for dyeing keratin fibres

The present invention relates to a packaging article comprising i) an envelope defining at least one cavity, the envelope comprising water-soluble or liposoluble fibers, ii) at least one anhydrous dye composition containing at least one oxidation dye; and iii) optionally at least one anhydrous oxidizing agent, preferably in powder form; it being understood that the dye composition ii) and the chemical oxidizing agent iii), when it is present, are in one of the cavities of the envelope i). Another subject of the invention is the use of the packaging article for dyeing keratin fibers, and a process for dyeing keratin fibers using the said article. The use of the packaging article makes it possible to obtain dye compositions having good dyeing properties, which are easy to apply and which make it possible to obtain powerful coloring of the hair.

Packaging article comprising an envelope and an anhydrous dye composition comprising an oxidation dye, use of the same and process for dyeing keratin fibres

The invention relates to the use of at least one amphiphilic copolymer comprising at least one hydrophilic block and at least one hydrophobic block to stabilize dispersions of insoluble organic compounds comprising at least one group that absorbs UV radiation, which is in the form of particles with a mean size of between 10 nm and 5 &mgr;m, and also to dispersions stabilized with these amphiphilic copolymers and to cosmetic compositions for topical application, in particular antisun compositions, containing them.

USE OF AMPHIPHILIC COPOLYMERS TO STABILIZE DISPERSIONS OF INSOLUBLE ORGANIC COMPOUNDS FOR SCREENING OUT UV RADIATION, DISPERSIONS STABILIZED WITH THESE COPOLYMERS AND COSMETIC COMPOSITIONS CONTAINING THEM

Improvedly photostable UV-photoprotecting cosmetic/dermatological compositions for the skin and/or the hair contain (a) a UV-photoprotective amount of at least one dibenzoylmethane sunscreen, e.g., 4-(tert-butyl)-4&prime;-methoxydibenzoylmethane or 4-isopropyldibenzoylmethane, advantageously (a&prime;) a UV-photoprotective amount of at least one 1,3,5-triazine sunscreen, e.g., 2-&lsqb;(p-(tert-butylamido&rsqb;-4,6-bis&lsqb;(p-(2&prime;ethylhexyl-1&prime;-oxycarbonyl)anilino&rsqb;-1,3,5-triazine or 2,4,6-tris&lsqb;p-(2&prime;-ethylhexyl-1&prime;-oxycarbonyl)anilino&rsqb;-1,3,5-triazine, (b) an effective sunscreen photostabilizing amount of 1,1,1-tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane, formulated into (c) a topically applicable, cosmetically acceptable vehicle, diluent or carrier therefor.
