Abstract

A 1,4-diazacycloheptane derivative and an oxidative hair colorant containing the derivative as a primary intermediate is presented. The 1,4-diazacycloheptane derivative is of the formula: ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another represent hydrogen, a C.sub.1-4 alkyl or hydroxyalkyl group or a C.sub.2-4, dihydroxyalkyl group, X and Y independently of one another represent hydrogen, chlorine, fluorine, a C.sub.1-4 alkyl, hydroxyalkyl, aminoakyl or alkoxy group, a C.sub.2-4 dihydroxyalkyl group or an allyl group and R.sup.5 and R.sup.6 independently of one another represent hydrogen or a C.sub.1-4 alkyl group. Natural color tones can be obtained in keratin fibers with oxidative hair colorants containing the 1,4-diazacycloheptane derivative, without the use of additional primary intermediates.
