ABSTRACT:
Polyvalent metal salts of 2-mercaptopyridine-N-oxide which are made into fine powder in which particles having a size below 0.2 micron are contained in amounts not smaller than 50 wt %.
Preparing process of the above and antibacterial compositions comprising the above are also disclosed.
When the finely powdered polyvalent metal salts of 2-mercaptopyridine-N-oxide are incorporated into shampoo or rinse compositions, dispersion stability of the salts is remarkably improved with the enhanced adsorbability of the particles on the skin and hair, thus antibacterial and dandruff-removing actions owing to the salts are further improved.
