PURPOSE: A two-pack oxidation type hair dye composition, obtained by incorporating a water-soluble ammonium salt with ammonia as an alkali agent, and capable of decoloring or dyeing the hair to a deep color at a relatively low pH. n CONSTITUTION: A two-pack oxidation type hair dye composition, obtained by incorporating ammonia as an alkali agent with a water-soluble ammonium salt, preferably ammonium sulfate or ammonium chloride. Preferably, the composition contains 1W5wt% water-soluble ammonium salt in a mixture solution of the first agent with the second agent of the two-pack oxidation type hair dye, and is prepared by incorporating both to give 7W9.5pH of the mixture solution. n COPYRIGHT: (C)1985,JPO&Japio |
