Insoluble in water. Solubility: water 15mg/kg; 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 react with cationic and non-ionic surfactants forming insoluble precipitate, unstable in the light and oxidizer, when at higher temperatures ,it is not stable to acids and bases . It is not compatible with EDTA, non-ionic surfactants make it partially deactivated. When with the presence of heavy metals, chelation or anti-sequestration will occur, and these chelates are insoluble in water.
