Abstract
The present invention relates to an agent for oxidatively dyeing keratin fibers, and in particular human hair, containing, in a cosmetic carrier, (a) at least one oxidation dye precursor of the developer type, and (b) isatin, and (c) at least one alkalizing agent from the group consisting of ammonia, monoethanolamine, 2-amino-2-methylpropanol, arginine, lysine, ornithine, and histidine.
Claims20
An agent for oxidatively dyeing keratinous fibers, comprising, in a cosmetic carrier:
- (a) at least one developer-type oxidation dye precursor, and
- (b) isatin, and
- (c) at least one alkalizing agent selected from the group consisting of ammonia, monoethanolamine, 2-amino-2-methylpropanol, arginine, lysine, ornithine, and histidine.
The agent according to 12, wherein the one or more oxidation dye precursors of the coupler type (d) is present in a total amount, relative to the total weight of the agent, of 0.001 to 10 wt %.
The agent according to 12, wherein the one or more oxidation dye precursors of the coupler type (d) is present in a total amount, relative to the total weight of the agent, of 0.1 to 3.5 wt %.
A multi-component packaging unit (kit-of-parts) for oxidatively dyeing keratinous fibers, comprising, packaged separately from one another,
- a first container having a dyeing agent (F), which contains
- (a) at least one developer-type oxidation dye precursor, and
- (b) isatin, and
- (c) at least one alkalizing agent from the group consisting of ammonia, monoethanolamine, 2-amino-2-methylpropanol, arginine, lysine, ornithine, and histidine, and
- a second container having an oxidizing agent composition (Ox), which contains
- (c) at least one oxidizing agent from the group consisting of hydrogen peroxide and its addition products to organic or inorganic compounds.
