Abstract:
1. A method for producing a suspension, emulsion, or dispersion of de-agglomerated particles of pyrithione salts, comprising contacting agglomerated pyrithione salt particles with an de-agglomerating agent, in the presence of sonic energy, to produce said suspension, emulsion, or dispersion of de-agglomerated particles of pyrithione salts, wherein said de-agglomerating agent is an electrolyte, alone or in combination with an agent selected from the group consisting of surfactants, dispersants, and combinations thereof, and, wherein said electrolyte is selected from the group consisting of alkali metal or alkaline earth metal salts, alkali metal or alkaline earth metal oxides, alkali metal or alkaline earth metal hydroxides, zinc chloride, zinc oxide, zinc hydroxide and combinations thereof and wherein the de-agglomerated pyrithione salt is chemically identical to that of the agglomerated particles of pyrithione salts.
