Abstract
Abstract Stable aqueous dispersion system of antifungus agents is obtainable by dispersing 2-mercaptopyridine-N-oxide (referred to Mept compounds) with a specified polymer compound, for example , polyglycol/polyamine condensation resin. The dispersion system is resistant to salts and, even after once frozen and melted, it remains unchanged. When the dispersion is incorporated into bases for shampoos, hair rinses and hair lotions, conventional problems of coagulation or separation of the articles are obviated.
