Abstract
The present disclosure relates to a composition for bleaching and simultaneously dyeing keratin fibers, comprising at least one dye chosen from meta-substituted ortho-nitroanilines and addition salts thereof, at least one peroxygenated salt and at least one alkaline agent. The present disclosure further relates to the process for bleaching and dyeing keratin fibers using this composition, and also to the use of this composition for bleaching and simultaneously dyeing keratin fibers.
Claims30
A composition for bleaching and simultaneously dyeing keratin fibers, comprising:
- at least one dye chosen from meta-substituted ortho-nitroanilines and the addition salts thereof, with the proviso that the meta-substituted ortho-nitroaniline is not 4-nitro-meta-phenylenediamine;
- at least one peroxygenated salt;
- and
- at least one alkaline agent.
A process for bleaching and simultaneously dyeing keratin fibers, comprising applying to the keratin fibers a composition comprising:
- at least one dye chosen from meta-substituted ortho-nitroanilines and the addition salts thereof, with the proviso that the meta-substituted ortho-nitroaniline is not 4-nitro-meta-phenylenediamine;
- at least one peroxygenated salt;
- and
- at least one alkaline agent.
A multi-compartment device, comprising at least two compositions, the mixing of which leads to a composition comprising:
- at least one dye chosen from meta-substituted ortho-nitroanilines and the addition salts thereof, with the proviso that the meta-substituted ortho-nitroaniline is not 4-nitro-meta-phenylenediamine;
- at least one peroxygenated salt;
- and
- at least one alkaline agent.
A multi-compartment device comprising at least one first compartment containing at least one composition (A) comprising, in a suitable dyeing medium, at least one dye chosen from meta-substituted ortho-nitroanilines and the addition salts thereof, with the proviso that the meta-substituted ortho-nitroaniline is not 4-nitro-meta-phenylenediamine, at least one second compartment containing at least one anhydrous composition (B) comprising at least one peroxygenated salt, and at least one alkaline agent, and at least one third compartment containing at least one aqueous hydrogen peroxide composition (E).
A multi-compartment device comprising at least one first compartment containing at least one anhydrous composition (C) comprising at least one dye chosen from meta-substituted ortho-nitroanilines and the addition salts thereof, with the proviso that the meta-substituted ortho-nitroaniline is not 4-nitro-meta-phenylenediamine, at least one peroxygenated salt, and at least one alkaline agent, and at least one second compartment containing at least one aqueous hydrogen peroxide composition (E).
A multi-compartment device comprising at least one first compartment containing at least one anhydrous composition (B) comprising at least one peroxygenated salt, and at least one alkaline agent, and at least one second compartment containing at least one composition (D) comprising, in a suitable dyeing medium, at least one dye chosen from meta-substituted ortho-nitroanilines and the addition salts thereof and hydrogen peroxide, with the proviso that the meta-substituted ortho-nitroaniline is not 4-nitro-meta-phenylenediamine.
