  • Chemical method of making a suspension, emulsion or dispersion of pyrithione particles
    Patent number: 8709460
    Abstract: A method for producing a suspension, emulsion or dispersion of de-agglomerated particles (advantageously submicron-sized particles) of pyrithione salts comprising contacting agglomerated pyrithione salt particles with a de-agglomerating agent to produce the desired de-agglomerated pyrithione salt particles. Also disclosed is a method for making de-agglomerated submicron-sized particles of pyrithione salts comprising a heating step. Also disclosed are the particles made by the above methods and compositions comprising the particles and a base medium.
    Type: Grant

  • Non-spherical and non-platelet forms of pyrithione salts and methods of making same
    Patent number: 6242007
    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 acid or a water-soluble salt of pyrithione and a water-soluble polyvalent metal salt in the presence of an ionic surfactant composition at temperature from about 20° C. to about 60° C. and at a pH from 4-9 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.
