Application:

In medical
Zinc pyrithione is best known for its use in treating dandruff and seborrhoeic dermatitis. It also has antibacterial properties and is effective against many pathogens from the Streptococcus and Staphylococcus genera. Its other medical applications include treatments of psoriasis, eczema, ringworm, fungus, athletes foot, dry skin,atopic dermatitis, tinea, and vitiligo.

In paint
Due to its low solubility in water (8 ppm at neutral pH), zinc pyrithione is suitable for use in outdoor paintsand other products that provide protection against mildew and algae. It is an effective algaecide. It is chemically incompatible with paints relying on metal carboxylate curing agents. When used in latex paints with water containing high amount of iron, a sequestering agent that will preferentially bind the iron ions is needed. Its decomposition by ultraviolet light is slow, providing years of protection even against direct sunlight.

In sponges
Zinc pyrithione is also used as an antibacterial treatment for household sponges.





Zinc pyrithione, also known as zinc pyrithione or zinc omadin, is a colorless solid and is almost insoluble in water under neutral conditions at room temperature. This zinc complex was synthesized as early as the 1930s and used as an external antifungal or antibacterial agent. Zinc pyrithione is widely used in anti-dandruff shampoos such as Helensindus, so it is also called anti-dandruff factor.
