Abstract
The invention relates to a composition for the oxidation dyeing of keratin fibers, and in particular human keratin fibers such as the hair, comprising, in a medium which is suitable for dyeing, at least one substituted para-aminophenol as oxidation base, and/or 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and/or at least one of the addition salts thereof with an acid, as coupler, as well as to the dyeing process using this composition.
Claims18
A composition for the oxidation dyeing of keratin fibers comprising, in a medium which is suitable for dyeing:
- (a) at least one oxidation base chosen from a substituted para-aminophenol corresponding to formula (I), and an addition salt thereof with an acid:
- 3
- in which:
- R1 is chosen from hydrogen, fluorine, C1-C4 alkyl radicals, C1-C4 monohydroxyalkyl radicals, C2-C4 polyhydroxyalkyl radicals, C1-C4 alkoxyalkyl radicals, C1-C4 aminoalkyl radicals, and monohydroxy(C1-C4)alkylamino(C1-C4)alkyl radicals;
- R2 is chosen from hydrogen, fluorine, C1-C4 alkyl radicals, C1-C4 monohydroxyalkyl radicals, C2-C4 polyhydroxyalkyl radicals, C1-C4 aminoalkyl radicals, cyano(C1-C4)alkyl radicals, and C1-C4 alkoxyalkyl radicals;
- and
- provided that at least one, and only one, of R1 and R2 is hydrogen;
- and
- (b) a coupler chosen from 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and an addition salt thereof with an acid;
- wherein said composition does not include an oxidation base chosen from pyrimidine, pyrimidine derivatives, 2-β-hydroxyethyl-para-phenylenediamine, and addition salt thereof with an acid.
A process for dyeing keratin fibers comprising the steps of 1) applying to said fibers at least one dye composition, and 2) developing a color at acidic, neutral or alkaline pH with the aid of an oxidizing agent which is added to the dye composition only at the time of use, or which is present in an oxidizing composition that is applied simultaneously with the dye composition or sequentially after application of the dye composition, said at least one dye composition comprising, in a medium which is suitable for dyeing:
- (a) at least one oxidation base chosen from a substituted para-aminophenol corresponding to formula (I), and an addition salt thereof with an acid:
- 4
- in which:
- R1 is chosen from hydrogen, fluorine, C1-C4 alkyl radicals, C1-C4 monohydroxyalkyl radicals, C2-C4 polyhydroxyalkyl radicals, C1-C4 alkoxyalkyl radicals, C1-C4 aminoalkyl radicals, and monohydroxy(C1-C4)alkylamino(C1-C4)alkyl radicals;
- R2 is chosen from hydrogen, fluorine, C1-C4 alkyl radicals, C1-C4 monohydroxyalkyl radicals, C2-C4 polyhydroxyalkyl radicals, C1-C4 aminoalkyl radicals, cyano(C1-C4)alkyl radicals, and C1-C4 alkoxyalkyl radicals;
- provided that at least one, and only one, of R1 and R2 is hydrogen;
- and
- (b) a coupler chosen from 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and an addition salt thereof with an acid;
- wherein said composition does not include an oxidation base chosen from pyrimidine, pyrimidine derivatives, 2-β-hydroxyethyl-para-phenylenediamine, and an addition salt thereof with an acid.
A multi-compartment dyeing kit comprising a first compartment that contains a dye composition for the oxidation dyeing of keratin fibers comprising, in a medium which is suitable for dyeing:
- (a) at least one oxidation base chosen from a substituted para-aminophenol corresponding to formula (I), and an addition salt thereof with an acid:
- 5
- in which:
- R1 is chosen from hydrogen, fluorine, C1-C4 alkyl radicals, C1-C4 monohydroxyalkyl radicals, C2-C4 polyhydroxyalkyl radicals, C1-C4 alkoxyalkyl radicals, C1-C4 aminoalkyl radicals, and monohydroxy(C1-C4)alkylamino(C1-C4)alkyl radicals;
- R2 is chosen from hydrogen, fluorine, C1-C4 alkyl radicals, C1-C4 monohydroxyalkyl radicals, C2-C4 polyhydroxyalkyl radicals, C1-C4 aminoalkyl radicals, cyano(C1-C4)alkyl radicals, and C1-C4 alkoxyalkyl radicals;
- provided that at least one, and only one, of R1 and R2 is hydrogen;
- and
- (b) a coupler chosen from 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and the addition salts thereof with an acid;
- wherein said composition does not include an oxidation base chosen from pyrimidine, pyrimidine derivatives, 2-β-hydroxyethyl-para-phenylenediamine, and an addition salt thereof with an acid, and
- a second compartment that contains an oxidizing composition.
