PACKAGED HAIR COLOURING COMPOSITION

摘要

Packaged hair colouring composition comprising a stable aqueous hair colouring composition comprising a compound of formula (I), wherein D is a chromophore; X and Y are independently selected from halogen and -SR', provided that at least one of X and Y is -SR', wherein R' is selected from H, C1-C4 alkyl, (CH2)nCOOH, (CH2)nCONH2, (CH2)nSO3H, (CH2)nCOOM, (CH2)nPO3H, (CH2)nOH, (CH2)nSSO3<->, (CH2)nNR"2, (CH2)nN<+>R"3, PhSSO3<->, PhSO3H, PhPO3H, PhNR"2, PhN<+>R"3, -CN, SO3<->, (CH2)2CH(SH)R"(CH2)3COOH, -CH2CHOHCH2SH, and formulas (II), (III), (IV), (V), (VI), (VII), (VIII), (IX), (X), (XI), (XII), (XIII), -CH2CH2NH2; n is an integer in the range of 1 to 4 wherein within the same molecule n is not necessarily the same integer; and M is a cation of alkaline earth metal, alkali metal, NH4<+> or NR"3<+>; L is a linking moiety; Z is selected from pyrimidine or triazine; R'' is C1-C4 alkyl; and a package for said hair colouring composition. The packaged hair colouring compositions of the present invention provide improved wash fastness of dye on hair, less colour fade over time, improved consumer acceptance in terms of providing a single packaged hair dye composition and improved product stability.
