Abstract
A ready-to-use composition for the oxidation dyeing of keratin fibers, and, in particular, human keratin fibers such as the hair, including at least one oxidation base, at least one ammonia-generating 2-electron oxidoreductase type enzyme, and at least one donor for the enzyme, as well as a dyeing process using this composition.
Claims46
A ready-to-use composition for the oxidation dyeing of keratin fibers, comprising:
- at least one oxidation base,
- at least one ammonia-generating 2-electron oxidoreductase-type enzyme,
- and at least one donor for said at least one enzyme.
A method of oxidation dyeing of keratin fibers, comprising
- applying at least one ready-to-use dye composition to said keratin fibers for a period of time sufficient to develop a desired coloration, wherein said at least one ready-to-use composition comprses:
- at least one oxidation base,
- at least one ammonia-generating 2-electron oxidoreductase-type enzyme,
- and at least one donor for said at least one enzyme.

A multi-compartment device for oxidation dyeing of keratin fibers, comprising at least two compartments, wherein
- a first compartment comprises a first composition comprising at least one oxidation base;
- a second compartment comprises a second composition comprising at least one ammonia-generating 2-electron oxidoreductase-type enzyme;
- one of the first composition and the second composition comprises at least one donor for said at least one enzyme;
- and
- said first composition and said second composition are mixed prior to the oxidation dyeing of keratin fibers.
