Abstract

PURPOSE:To obtain a hair producing agent having raised hair forming effects by adding 2-methyl-2,4-pentanediol to 6-(1piperidinyl)-2,4-pyrimidinediamine-3- oxide or 2,4-diamino-6piperidino-3-sulfoxypyridinium hydroxide. CONSTITUTION:2-Methyl-2,4-pentanediol is added to 6-(1-piperidinyl)-2,4- pyrimidinediamine-3-oxide (compound I for short) or 2,4-diamino-6-piperidino-3- sulfoxypyridinium hydroxide (compound II for short) and blended with proper amounts of other ordinary components and pharmacentically manufactured by a conventional procedure to give the aimed substance. The amount of the compound shown by formula I or formula II is 0.05-5.0 pts.wt. based on the total amounts of the preparation and the amount of 2-methyl-2,4-pentanediol blended is 0.5-30wt.% based on the total amounts of the preparation. The aimed substance can be processed into any type of hair producing agent such as lotion, milky lotion, cream, gel or aerosol.
