Several novel heterocyclic compounds based on 1,2,3,4-tetrahydroquinoline and 2,3-dihydroindole have been investigated for their application of colour keratin fibres as blue oxidative dye precursors, especially to human hair. The colourants we studied contained anyone of these dyes (concentration range from 0.005% to 6%), and some common oxidative hair dyes, such as p-phenylenediamine, toluene-2,5-diamine sulphate. Experiments were carried out on the method of mixing hair colourants with H(2)O(2) gel at the ratio of 1 : 1, accompanied by pH = 8 similar to 11. It is demonstrated that 1,2,3,4-tetrahydroquinoline derivatives could be considered as an excellent candidate for blue dyes, and N-methyl-7-amino-1,2,3,4-tetrahydroquinoline is the most outstanding one among this kind of compounds. They own significant advantages of colour purity, stability and fastness. On the other hand, 2,3-dihydroindoles show the similar colours but not stable and brilliant enough.
