Abstract

Official abstract text for this publication.

The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains the coupling oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol in combination with the oxidation base 2-methoxymethyl-para-phenylenediamine.

First claim

Opening claim text (preview).

What is claimed is: 1. An agent for the oxidative dyeing of keratinous fibers, comprising: (A) a coupling oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol and/or at least one of its physiologically tolerated salts, and (B) an oxidation base 2-methoxymethyl-para-phenylenediamine and/or at least one of its physiologically tolerated salts, wherein the agent is substantially free of any resorcinol compound of structure (I) in which X means a hydrogen atom or a C1-C10 alkyl group, wherein the agent is further substantially free of any chlorinated aromatic nitro dyes, and wherein the agent is further substantially free of dissolved hydrogen peroxide. 2. The agent according to claim 1 , wherein the oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol and/or at least one of its physiologically tolerated salts comprises 0.01 wt % to 5.0 wt % based on the total weight of the agent. 3. The agent according to claim 1 , wherein the oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol and/or at least one of its physiologically tolerated salts comprises 0.03 wt % to 3.0 wt % based on the total weight of the agent. 4. The agent according to claim 1 , wherein the oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol and/or at least one of its physiologically tolerated salts comprises 0.05 wt % to 1.5 wt % based on the total weight of the agent. 5. The agent according to claim 1 , wherein the oxidation base 2-methoxymethyl-p-phenylenediamine and/or at least one of its physiologically tolerated salts comprises 0.01 wt % to 5.0 wt % based on the total weight of the agent. 6. The agent according to claim 1 , wherein the oxidation base 2-methoxymethyl-p-phenylenediamine and/or at least one of its physiologically tolerated salts comprises 0.03 wt % to 3.0 wt % based on the total weight of the agent. 7. The agent according to claim 1 , wherein the oxidation base 2-methoxymethyl-p-phenylenediamine and/or at least one of its physiologically tolerated salts comprises 0.05 wt % to 1.5 wt % based on the total weight of the agent. 8. The agent according to claim 1 , wherein the oxidation base 2-methoxymethyl-para-phenylenediamine or at least one of its physiologically tolerated salts (B) and the oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol or at least one of its physiologically tolerated salts (A) are present at a molar ratio (B)/(A) of 1.0 to 2.3. 9. The agent according to claim 1 , wherein the oxidation base 2-methoxymethyl-para-phenylenediamine or at least one of its physiologically tolerated salts (B) and the oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol or at least one of its physiologically tolerated salts (A) are present at a molar ratio (B)/(A) of 1.1 to 2.0. 10. The agent according to claim 1 , wherein the oxidation base 2-methoxymethyl-para-phenylenediamine or at least one of its physiologically tolerated salts (B) and the oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol or at least one of its physiologically tolerated salts (A) are present at a molar ratio (B)/(A) of 1.3 to 1.6. 11. The agent according to claim 1 , wherein the agent further comprises at least one additional coupling oxidation dye precursor and/or at least one of its physiologically tolerated salts in a total amount of 0.001 wt % to 5.0% based on the total weight of the agent. 12.
