Abstract
The present disclosure relates to compositions for colouring keratin fibres, in particular human hair, where the composition comprises, in a cosmetic carrier, at least one neutral tetraaminopyrimidine derivate of the general formula (I), (I) in which R1, R2 independently of one another are a group of the formulae (II), (III) or (IV) —(CH2)n— (II) —(CH2)m—O—(CH2)p— (III) —(CH2)m—N(R3)-(CH2)p— (IV) n is 2, 3, 4, 5 or 6, m, p in each case independently of one another are 1, 2 or 3, Y is —OH, —NH2 or —NH-alkyl, R3 is a hydrogen atom, a C1-C6-alkyl group or is a C2-C6-alkenyl group.
