Claims20
An agent for oxidatively dyeing keratinous fibers, in particular human hair, comprising—in a cosmetic carrier—
- (a) at least one oxidation dye precursor of the developer type, selected from the group including p-toluenediamine, 2-methoxymethyl-p-phenylenediamine, 2-(2-hydroxyethyl)-p-phenylenediamine, N,N-bis(2-hydroxy-hydroxyethyl)-p -phenylenediamine, p-phenylenediamine and the physiologically acceptable salts thereof;
- (b) isatin and
- (c) at least one oxidizing agent from the group consisting of hydrogen peroxide and its addition products with organic or inorganic compounds.
A multi-component packaging unit (kit-of-parts) for oxidatively dyeing keratin fibers, comprising, packaged separately from one another,
- a first container having a dye (F), which comprises
- (a) at least one oxidation dye precursor of the developer type, selected from the group including p-toluenediamine, 2-methoxymethyl-p-phenylenediamine, 2-(2-hydroxy-hydroxyethyl)-p-phenylenediamine, N,N-bis(2-hydroxy-hydroxyethyl) -p-phenylenediamine, p-phenylenediamine and the physiologically acceptable salts thereof;
- (b) isatin and
- a second container having an oxidation composition (Ox), which comprises
- (c) at least one oxidizing agent selected from the group consisting of hydrogen peroxide and its addition products with organic or inorganic compounds.
