| abstract |
The invention relates to means for dyeing keratin-containing fibres comprising at least one dye precursor for a natural dye analogue selected from the group of indole or indoline derivatives, at least one triglyceride of formula (I), where at least two of the groups R1, R2 and R3 independently = pentadec-8-enyl, heptadec-8-enyl, heptadeca-8, 11-dienyl, heptadeca-8, 11, 14-trienyl, tricos-14-enyl or hencos-11-enyl and at most one of R1, R2 and R3 = at least one (C11 to C25) alkyl, (C11 to C25) alkenyl, (C11 to C25) alkanedienyl, or (C11 to C25) alkanetrienyl group, free of additional oxidising agents which have an improved dyeing power, in particular, of grey hair. |
