Definitions

  • ABSTRACT An improved dye compound l-methylamino-Z- nitro'-4-(2'-hydroxyethyl)-methylaminobenzene and a method of making it.
  • Nitroparaphenylenediamine is a known active ingredient used in dyes for living hair.
  • trihydroxyalkylated derivatives of nitroparaphenylenediamine has been suggested, and especially those trihydroxyethyls having a hydroxyethyl radical on the amino group in the ortho position of the nitro group and two hydroxyethyl radicals on the amino group in the meta position of the nitro group.
  • the object of the present invention is to provide a new nitrated hair dye and the coloring compositions which can be made with this new dye.
  • the new dye is 1-methylamino-2-nitro-4-(2-hydroxyethyl)- methylaminobenzene.
  • the invention also comprises a method of manufacturing this new dye.
  • This process consists in starting with l-amino- 2- nitro-4-methylaminobenzene, transforming this by methylation into l-methylamino-2-nitro-4-methylaminobenzene, and subjecting the resulting product to hydroxyethylation, using a glycol halohydrin.
  • the amine function in position 1 is methylated by blocking the position of the hydrogen atom carried by the amine group in position 4with acetic anhydride, then blocking the position of one of the hydrogen atoms of the amine function in position 1 with paratoluene-sulfochloride, methylating the resulting product with a neutral methyl sulfate, and finally freeing the two previously blocked positions using first sulfuric acid to detach the tosyl group carried by the nitrogen atom in position 1, and then hydrochloric acid to detach the acetyl group carried by the nitrogen atom in position 4.
  • the nitro group is readily hydroxyethylated in the meta position with a commercially satisfactory yield, and without impurities.
  • a methyl group on one of the amine groups may be easily substituted on the initial product, after which a hydroxyethyl group is substituted on the other amino group, a product which will produce constant, reproducible, results is obtained, since there is no contamination by any secondary coloring agent.
  • the hair dyes comprising the composition according to the invention are simple aqueous solutions containing the composition, preferably having an alkaline pH. No oxidizing agent is required to develop the color.
  • Various additives known in the hair-coloring art may be included, such as organic solvents, thickening agents, detergents, and lacquers.
  • the time during which the hair-coloring solutions should be kept in contact with the hair varies within broad limits, but is preferably between 5 and 30 minutes.
  • the temperature of application may also be varied, but in most cases the dye is applied at room temperature.
  • the pH of these solutions is usually between 7 and 10 and preferably between 8 and 9.5.
  • alkaline products which may be used to adjust the pH are ammonia, any organic base, for example and alkylamine, an alkanolamine, or a heterocyclic amine.
  • concentration of the dye may be varied over a wide range, but this concentration is preferably between 0.l and 3 percent.
  • the dye according to the invention may be mixed with other dyes, whether nitrated, azo,
  • anthraquinone or of any other type conventionally used for dyeing hair.
  • EXAMPLE 2 1-methylamino-2-nitr0-4-(2'-hydroxy- This solution is applied to completely white hair. It is left for 15 to 20 minutes, after which the hair is rinsed, shampooed, and dried. A clear copperish chestnut shade is obtained.
  • composition for dyeing hair comprising an aqueous solution containing hair-dyeing amounts of the compound of claim 1.
  • a hair-dyeing composition as claimed in claim 2 having a pH between 8 and 9.5.
  • a hair-dyeing composition as claimed in claim 2 in which the concentration of said compound lies between 0.1 and 3 percent.
  • the method of dyeing human hair which comprises the step of applying thereto a composition containing dyeing amounts of 1-methylamino-2-nitro-4-(2'-hydroxyethyl)- methylaminobenzene.
