Abstract

Claims (40)

1 . A composition comprising:

at least one oxidation dye chosen from:

(i) at least one coupler chosen from: 6-hydroxybenzomorpholine of formula (I), addition salts thereof, solvates thereof and/or the solvates of salts thereof; hydroxyethyl-3,4-methylenedioxyaniline of formula (II), addition salts thereof, solvates thereof and/or the solvates of salts thereof; or 2-amino-5-ethylphenol of formula (III), addition salts thereof, solvates thereof and/or the solvates of salts thereof;

(ii) at least one base chosen from: 2-β-hydroxyethyl-para-phenylenediamine and addition salts thereof, solvates thereof and/or the solvates of salts thereof; 2-(γ-hydroxypropyl)-para-phenylenediamine and addition salts thereof, solvates thereof and/or the solvates of salts thereof; or 2-methoxymethyl-para-phenylenediamine and addition salts thereof, solvates thereof and/or the solvates of salts thereof; or

(iii) mixtures of any two or more oxidation dyes thereof;

propane-1,3-diol;

at least one alkaline agent; and

at least one fatty substance other than fatty acids.

2 . The composition of claim 1 , wherein the at least one oxidation dye is chosen from the (i) coupler(s).

3 . The composition of claim 2 , wherein the total amount of the coupler(s) (i) ranges from 0.001% to 20% by weight, relative to the total weight of the composition.

4 . The composition of claim 1 , wherein the total amount of propane-1,3-diol ranges from 0.01% to 25% by weight, relative to the total weight of the composition.

5 . The composition of claim 1 , wherein the at least one alkaline agent is chosen from alkanolamines.

6 . The composition of claim 1 , wherein the total amount of the alkaline agent(s) ranges from 0.1% to 40% by weight, relative to the total weight of the composition.

7 . The composition of claim 1 , wherein the at least one fatty substance other than fatty acids comprises at least one liquid fatty substance other than fatty acids.

8 . The composition of claim 1 , wherein the at least one fatty substance other than fatty acids comprises at least one solid fatty substance other than fatty acids.

9 . The composition of claim 1 , wherein the total amount of fatty substance(s) other than fatty acids ranges from 5% to 30% by weight, relative to the total weight of the composition.

10 . The composition of claim 8 , wherein the total amount of solid fatty substance(s) other than fatty acids ranges from 5% to 30% by weight, relative to the total weight of the composition.

11 . The composition of claim 7 , wherein the total amount of liquid fatty substance(s) other than fatty acids ranges from 0.5% to 15% by weight, relative to the total weight of the composition.

12 . The composition of claim 1 , further comprising (iii) at least one additional coupler other than the (ii) at least one coupler.

13 . The composition of claim 1 , further comprising at least one surfactant.

14 . The composition of claim 13 , wherein the at least one surfactant is chosen from anionic surfactants, nonionic surfactants, or mixtures thereof.

15 . The composition of claim 1 , further comprising at least one sequestrant.

16 . The composition of claim 1 , further comprising at least one thickening polymer.

17 . The composition of claim 1 , wherein the composition is free of any chemical oxidizing agents.

18 . The composition of claim 1 , further comprising at least one chemical oxidizing agent.

19 . A method for dyeing keratin fibres, comprising mixing at least a dyeing composition and an oxidizing composition, wherein the dyeing composition comprises:

at least one coupler chosen from: 6-hydroxybenzomorpholine of formula (I), addition salts thereof, solvates thereof and/or the solvates of salts thereof; hydroxyethyl-3,4-methylenedioxyaniline of formula (II), addition salts thereof, solvates thereof and/or the solvates of salts thereof; 2-amino-5-ethylphenol of formula (III), addition salts thereof, solvates thereof and/or the solvates of salts thereof; or mixtures thereof;

propane-1,3-diol;

at least one alkaline agent;

at least one fatty substance other than fatty acids; and

optionally at least one oxidation base; and

wherein the oxidizing composition comprises at least one chemical oxidizing agent.

20 . A multi-compartment device, comprising:

at least a first compartment comprising a dyeing composition comprising:

at least one coupler chosen from: 6-hydroxybenzomorpholine of formula (I), addition salts thereof, solvates thereof and/or the solvates of salts thereof; hydroxyethyl-3,4-methylenedioxyaniline of formula (II), addition salts thereof, solvates thereof and/or the solvates of salts thereof; 2-amino-5-ethylphenol of formula (III), addition salts thereof, solvates thereof and/or the solvates of salts thereof; or mixtures thereof;

propane-1,3-diol;
