Also known as zinc pyrithione, zinc pyrithione, pyrithione complexes of zinc bromide, zinc Omadine that zinc in the early 1930s was synthesized and used as a topical antifungal or antibacterial agent. At room temperature is a white to yellow crystalline powder. Slight characteristic odor. Insoluble in water. pH = 8 Water 35mg / kg; Ethanol 100mg / kg; polyethylene glycol (PEG400) 2000mg / kg. A pH optimum range of 4.5 to 9.5; mass fraction of 10% suspension pH3.6. Zinc pyrithione with cationic and non-ionic surfactants form insoluble precipitate, light and unstable oxidizer, when higher temperatures of acids and bases are not stable. It is not compatible with EDTA, non-ionic surfactants make it partially deactivated. When the presence of heavy metals, chelation or anti-sequestration will occur, and these chelates insoluble in water.
