Abstract: PURPOSE:The titled composition obtained by blending a surface active agent with a metal salt of 2-mercaptopyridine having specific particle size distribution, as an anti-dandruff agent, capable of stabilizing easily dispersion of the metal salt, having high anti-dandruff effect. CONSTITUTION:The titled composition obtained by blending a surface active agent (e.g., anionic surface active agent, ampholytic surface active agent, nonionic surface active agent, etc.) with fine particles of a metal salt of 2-mercaptopyridine-N-oxide (Mt-pt for short) having particle size distribution of >=50wt% particles having 1.0mum particle diameter, to give the titled composition. Dispersion stabilization is carried out easily by using the Me-pt having the particle size distribution, and adsorption of it on the scalp and the air after washing of hair is increased and anti-dandruff effect can be raised. Especially zinc salt having
