摘要:
Hair dye compositions without sensitizing potential but with improved dyeing properties for all shades comprise only 2-(2'-hydroxyethylamino)5-aminotoluene or the salts thereof as developing agent, or preferably in combination with the usual coupling agents, excluding 1-methoxy-2,4-diaminobenzene and 1-ethoxy-2,4-diaminobenzene.
