    Abstract: The invention relates to a ready-to-use composition for the oxidation dyeing of keratin fibres, and in particular human keratin fibres such as the hair, comprising, in a medium which is suitable for dyeing, para-phenylenediamine as first oxidation base, at least one para-aminophenol as second oxidation base, 2-methyl-5-N-(beta-hydroxyethyl)aminophenol as coupler and at least one enzyme of 2-electron oxidoreductase type in the presence of at least one donor for the said enzyme, and to the dyeing process using this composition.

    Abstract: Cosmetic and/or dermatological composition for treating keratinic fibres comprises a carrier, at least one 2-electron oxidoreductase enzyme, at least one substrate for the enzyme, and at least one anionic surfactant selected from acyl isethionates, acyl taurates, sulphosuccinates, acyl sarcosinates, acyl glutamates, alkoxylated carboxylic acids and their salts, sulphated fatty glucamides, alkyl galactoside uronates, and anionic alkyl polyglucoside derivatives. Preferably the enzyme is an animal, microbial or recombinant uricase and is present in an amount of 0.01-20 (preferably 0.1-5) wt.%. The substrate is selected from uric acid and its salts and is present in an amount of 0.01-20 (preferably 0.1-5) wt.%. The acyl isethionates and taurates are of formula RCH2CH2SO3M; R = R1COO or R1CONR2; R1 = an 8-30C aliphatic group; R2 = H or 1-4C alkyl; and M = H, NH4, Na, K or organic ammonium. The sulphosuccinates are of formula R1OOC-CH(SO3M)-CH2COOM. The acyl sarcosinates and glutamates are of formula R2CO-NR3-CHR4-COOM; R3 = Me; and R4 = H or R3 = H; and R4 = CH2CH2COOM. The alkoxylated carboxylic acids have 2-50 ethylene oxide groups. The alkoxylated carboxylic acids or salts are of formula R5(OC2H4)nOCH2COOA; R5 = 6-20C alkyl or (6-20C alkyl)phenyl; n = 3-10; and A = H, NH4, Na, K, Li, Mg, monoethanolammonium or triethanolammonium.
