Abstract:
The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising the use of one or more metal catalysts chosen from transition metal salts and rare-earth metal salts, and mixtures thereof and a composition (I) comprising at least 10% by weight of one or more fatty substances different from fatty acids, one or more oxidation dyes and one or more oxidizing agents.
Abstract:
The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dye(s), b) one or more titanium salts and b1) optionally at least one carboxylic acid, and c) one or more anionic thickening polymers derived from the polymerization of at least one monomer bearing an organic monoacid function, and d) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.
Abstract:
The present invention relates to a process for dyeing keratin fibers, in particular human keratin fibers such as the hair, in which the said fibers are treated using one or more cosmetic compositions comprising a) one or more ortho-diphenols, b) one or more organic salts of titanium and of at least one carboxylic acid, and c) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide generating systems.
Abstract:
The present invention relates to a composition for dyeing keratin fibres, comprising at least one fatty substance; at least one surfactant; at least one dye for keratin fibres, having a log P greater than or equal to 1.3; at least one alkaline agent; at least one chemical oxidizing agent; at least 0.5% by weight relative to the weight of the composition of at least one liquid non-ionic compound having a Hansen parameter δ H below 16 MPa ½; the fatty substance content representing in total at least 25% by weight relative to the total weight of the composition. The present invention also relates to a method using this composition, and to multi-compartment devices that are suitable for using this invention.
Abstract:
The present disclosure relates to a composition for lightening keratin fibres, comprising (a) hydrogen peroxide; (b) one or more carbonates and/or one or more carbonate-generating systems in a content of greater than or equal to 0.2%, relative to the weight of the composition, (c) one or more polyphosphorus derivatives, in a total content of greater than or equal to 0.5% by weight, relative to the total weight of the composition, and (d) one or more peroxygenated salts, said polyphosphorus derivative(s) being different from said peroxygenated salt(s). The pH of the composition is less than or equal to 10. The present disclosure also relates to a process of using the composition for lightening keratin fibres, and a device comprising the composition.
Abstract:
The present invention relates to a method for coloring keratin fibers, comprising: —a first step of applying to the fibers a dyeing composition (a) comprising one or more dyes chosen from chromene dyes and chroman dyes, and one or more liquid organic compounds having a Hansen so lubility parameter δH of less than or equal to 16 Mpa1/2, then —a second step of applying to the fibers an oxidizing composition (b) comprising one or more oxidizing agents and one or more alkaline agents, one or more metal salts and/or metal oxides being present in at least one of the compositions (a) and (b), and/or being applied during an additional step by means of a composition (c). The invention likewise relates to a kit suitable for implementing this method.
