Abstract
The present invention relates to dyeing compositions containing, in a medium appropriate for dyeing, at least one oxidation dye precursor and/or one or more couplers, a ketose as reducing agent and at least one laccase as oxidizing agent, to the use of the compositions for the oxidation dyeing of keratin fibers, and in particular human keratin fibers such as the hair, to dyeing processes using the compositions, and to dyeing kits using the compositions.
Claims69
A composition for dyeing of keratinous fibers comprising, in a medium appropriate for dyeing:
- a ketose as reducing agent, wherein said ketose is present in an amount ranging from 0.1 to 15% by weight with respect to the total weight of the composition,
- at least one laccase as oxidizing agent, and
- at least one oxidation dye.
A process for dyeing keratinous fibers comprising:
- applying to said fibers a dyeing composition comprising, in a medium appropriate for dyeing, at least one oxidation dye, and a ketose as reducing agent, wherein said ketose is present in an amount ranging from 0.1 to 15% by weight with respect to the total weight of said dyeing composition, and
- developing the color, in the presence of air, in an alkaline, neutral or acidic medium, using at least one laccase, wherein said at least one laccase is contained in said dyeing composition or in a separate oxidizing composition.
A process for dyeing keratinous fibers, comprising applying at least one dyeing composition to said fibers for a time sufficient to develop the desired coloring, wherein said dyeing composition comprises, in a medium appropriate for dyeing, a ketose as reducing agent, wherein said ketose is present in an amount ranging from 0.1 to 15% by weight with respect to the total weight of the composition, at least one laccase as oxidizing agent, and at least one oxidation dye.
A process for dyeing keratinous fibers, comprising applying a ready-for-use composition to said fibers for a time sufficient to develop the desired coloring, wherein said ready-for-use composition is obtained by mixing:
- a dyeing composition comprising, in a medium appropriate for dyeing, at least one oxidation dye, and a ketose as reducing agent, wherein said ketose is present in an amount ranging from 0.1 to 15% by weight with respect to the total weight of said dyeing composition, and
- an oxidizing composition comprising at least one laccase.
A multi-compartment kit for the dyeing of keratinous fibers, comprising at least two compartments, wherein one of the compartments contains a dyeing composition comprising at least one oxidation dye and at least one ketose, wherein said ketose is present in an amount ranging from 0.1 to 15% by weight with respect to the total weight of the dyeing composition, and another compartment contains an oxidizing composition comprising at least one laccase.
