Hair dye containing an enzyme and an oxidative dye precursor combines high dyeing capacity with good 'feel' or texture of the dyed hair when an organopolysiloxane with a bonded poly(N- acylalkylimine) unit is present

摘要

A hair dye containing: (A) an enzyme capable of oxidizing 2,5-diaminotoluene; (B) an oxidative dye precursor; and (C) an organopolysiloxane with a bonded poly(N- acylalkylimine) unit. A hair dye comprises: (A) an enzyme capable of oxidizing 2,5-diaminotoluene; (B) an oxidative dye precursor; and (C) an organopolysiloxane containing a poly(N- acylalkylimine) unit of formula (1) bonded to at least one of the Si chain atoms via an alkyleneimino group and with the imino group optionally quaternized. a = 1-5; R1 = H or 1-12C alkyl, cycloalkyl, aralkyl or aryl.
