Abstract

1349118 Hair dyes COSMITAL FRIBOURG SA 29 March 1972 [29 March 1971 28 Sept 1971] 14738/72 Heading C4P The invention comprises hair dyes of the general formula wherein R 1 and R 2 which may be the same or different are H or hydroxyethyl. They are prepared by (a) acetylation of chloro-p-phenylene diamine, nitration and saponification of the acetylated amino groups, (b) reaction of compounds of the above formula where R 1 and R 2 are H with ethylene chlorohydrin, (c) nitration of 1,5-dichloro-4-aminobenzene, acetylation of the amino group, reaction with ethanolamine and then saponification of the acetylated amino group or (d) reaction of 1-#-hydroxyethylamino - 2 - nitro - 4 - amino - 5 - chlorobenzene with ethylenechlorohydrin.
