Procedure

0.104 g. (.0005M) 2-methylamino-4-aminotoluene dihydrochloride (meta component) and .054 g. (.0005M) p-phenylenediamine (para component) was added to 3 ml. of ethanol and 20 g. of an aqueous solution composed of 1% Carbopol 934 (thickening agent) 0.1% Dupanol C (surfactant) and 3.8% ammonium acetate. The mixture was stirred with 3 ml. ammonium hydroxide (28%) and 20 ml. 6% hydrogen peroxide. A sample of human hair was dyed with this composition for 30 minutes at 30° C. A blue color was obtained which was perspiration, light and washfast, and superior in these characteristics to a similar dyeing obtained in which m-toluenediamine was used as the meta component.
