Abstract
The invention concerns a ready-to-use composition for dyeing human keratinous fibers and more particularly human hair, comprising in support suitable for dyeing keratinous fibers: (a) at least an enzyme such as laccase; (b) at least a cationic substantive or particular amphoteric polymer; (c) at least an oxidation coloring agent, as well as the dyeing methods using said composition.
Claims39
A composition for dyeing keratinous fibers comprising:
- (a) at least one enzyme of the laccase type;
- (b) at least one cationic substantive polymer, at least one amphoteric substantive polymer or at least one mixture thereof, wherein said substantive polymers are chosen from:
- (i) Polyquaternium-24;
- (ii) copolymers derived from monomers of dimethyldiallylammonium halide;
- (iii) homopolymers and copolymers derived from monomers of methacryloyloxyethyltrimethylammonium halide;
- (iv) poly(quaternary ammonium) polymers chosen from formulae (I), (II) and (III):
- polymers comprising units of formula (I):
- polymers comprising units of formula (II):
- polymers comprising units of formula (III):
- in which p is an integer ranging from 1 to 6, D is chosen from a bond, and
- —(CH2)r—CO— groups, in which r is chosen from 4 and 7;
- (v) polymers derived from monomers of vinylpyrrolidone comprising cationic units;
- and
- (vi) cationic polysiloxanes chosen from products derived from amodimethicones of formula (IV):
- (c) at least one oxidation dye and the acid addition salts thereof;
- with the proviso that the composition does not comprise hydrogen peroxide.
A method of dyeing keratinous fibers comprising applying to said keratinous fibers for a sufficient time to develop a desired color at least one dyeing composition comprising:
- (a) at least one enzyme of the laccase type;
- (b) at least one cationic substantive polymer, at least one amphoteric substantive polymer or at least one mixture thereof, wherein said substantive polymers are chosen from:
- (i) Polyquaternium-24;
- (ii) copolymers derived from monomers of dimethyldiallylammonium halide;
- (iii) homopolymers and copolymers derived from monomers of methacryloyloxyethyltrimethylammonium halide;
- (iv) poly(quaternary ammonium) polymers chosen from formulae (I), (II) and (III):
- polymers comprising recurring units of formula (I):
- polymers comprising recurring units of formula (II):
- polymers comprising recurring units of formula (III):
- in which p is an integer ranging from 1 to 6, D is chosen from a bond and
- —(CH2)r—CO— groups, in which r is chosen from 4 and 7;
- (v) polymers derived from monomers of vinylpyrrolidone comprising cationic units;
- and
- (vi) cationic polysiloxanes chosen from products derived from amodimethicone of formula (IV):
- (c) at least one oxidation dye and the acid addition salts thereof;
- with the proviso that the dyeing composition does not comprise hydrogen peroxide.
A method for dyeing keratinous fibres comprising:
- (a) storing a first composition,
- (b) storing a second composition separately from said first composition,
- (c) mixing the first composition with the second composition to form a mixture, and
- (d) applying said mixture to said keratinous fibres for a time sufficient to achieve a desired colouration,
- wherein said first composition comprises at least one oxidation dye and optionally comprises at least one substantive polymer, in a medium suitable for keratinous fibres, and
- wherein said second composition comprises at least one enzyme of the laccase type and optionally comprises at least one substantive polymer in a medium suitable for keratinous fibres, one of said first and second compositions comprising said at least one substantive polymer;
- with the proviso that neither the first nor second composition comprises hydrogen peroxide.
A multicompartment device or a dyeing kit comprising a first compartment containing a composition (A) comprising, in a medium appropriate for dyeing, at least one oxidation dye, and a second compartment containing a composition (B) comprising, in a medium appropriate for keratinous fibers, at least one enzyme of the laccase type, wherein said at least one of said composition (A) and said composition (B) comprises said at least one substantive polymer;
- with the proviso that neither composition (A) nor composition (B) comprises hydrogen peroxide.
