ABSTRACT:
The present invention relates to non-spherical and/or non-platelet pyrithione particles. Also disclosed is a method for producing non-spherical and/or non-platelet particles of pyrithione salts, comprising reacting pyrithione or a water-soluble salt of pyrithione and a water-soluble polyvalent metal salt in the presence of a dispersant at a temperature from about 20.degree. C. to about 60.degree. C. to produce non-spherical and/or non-platelet particles of pyrithione salts. The present invention further relates to particles made by the above methods and products, such as shampoos, soaps, and skin-care medicaments made using these particles.
