<p>A ready-for-use oxidation dyeing composition for keratin fibers comprises a dyeing medium containing: (a) oxidation base(s) selected from p-phenylene diamines, double bases. p-aminophenols and heterocyclic bases; (b) 2-electron oxido-reductase type enzyme(s); (c) donor(s) for (b); and (d) enzymatic mediator(s) which can increase the enzymatic activity of (b). A ready-for-use oxidation dyeing composition for keratin fibers comprises a dyeing medium containing: (a) at least one oxidation base selected from p-phenylene diamines of formula (I) and their acid addition salts, double bas p-aminophenols of formula (II) and their acid addition salts and heterocyclic bases; (b) at least one 2-electron oxido-reductase type enzyme; (c) at least one donor for (b); and (d) at least one enzymatic mediator which can increase the enzymatic activity of (b). R1, R2 = H, alkyl or monohydroxyalkyl; R3 = H, halo, alkyl or monohydroxyalkyl; R4 = H or alkyl; R5, R6 = H, halo, alkyl, monohydroxyalkyl, alkoxyalkyl, aminoalkyl or monohydroxyalkylaminoalkyl; all alkyl moieties have 1-4C. Independent claims are included for: (i) a dyeing process for keratin fibers, involving applying the above composition to the fibers at ambient temperature to 8 degrees C (preferably 35-50 degrees C) for sufficient time to develop the required color (preferably 1-60 (especially 5-30) minu and (ii) a multi-compartment dyeing kit, having at least one compartment containing component (a) and at least one compartment containing components (b)-(c) (the components being in suitable media).</p> |
