Abstract:
A method for producing submicron-sized particles of pyrithione salts having sizes from about 0.01 .mu.m to about 0.99 .mu.m, comprising reacting pyrithione or a water-soluble salt of pyrithione and a water-soluble polyvalent metal salt selected from the group consisting of zinc salts, tin salts, cadmium salts, bismuth salts, copper salts, zirconium salts, magnesium salts, aluminum salts, nitrate salts, acetate salts, sulfate salts, halide salts, and combinations thereof, in a pressurized turbulent flow reactor that generates pulverizing forces, said reaction producing said submicron sized particles of pyrithione salt.
