    • PROBLEM TO BE SOLVED: To provide a method for producing 1,4-diamino-2-methoxymethyl-benzene and its salt. SOLUTION: The method for producing 1,4-diamino-2-methoxymethyl-benzene represented by formula (I) (wherein n is 0 or 2; HX is an organic acid or an inorganic acid) and its physiologically permissible salt comprises converting 2-methoxymethyl-4-nitrophenol to 2-(2-methoxymethyl-4-nitro-phenoxy)-acetamide by reacting 2-methoxymethyl-4-nitrophenol with a haloacetamide, then converting the 2-(2-methoxymethyl-4-nitro-phenoxy)-acetamide to 2-methoxymethyl-4-nitroaniline and converting 2-methoxymethyl-4-nitroaniline to a compound represented by formula (I) by reducing the 2-methoxymethyl-4-nitroaniline in the presence of a catalyst and converting the compound represented by formula (I) to its acid addition product by using an inorganic acid or an organic acid when n is not 0.

    • PROBLEM TO BE SOLVED: To provide an applicator for an oxidation type hair dye repeatedly taking out by a small amount in a long period of time. SOLUTION: This applicator is provided with a first chamber 2 for storing liquid dye and a second chamber 3 for storing oxidizing agent. A product release part 4 is used for feeding the dye and the oxidizing agent. The chambers 2 and 3 are provided with one product outlets 5 and 6 respectively. The both product outlets 5 and 6 communicate with the inside of the product release part 4 in parallel to each other, so that reactive dye is made only outside the applicator 1, in the hair in particular. The product outlets 5 and 6 are preferably provided with one liquid permeable inserts 7 and 8 respectively made of, in particular, a felt, a sponge-like material, bristles, or a fabric for improving the coatability.
