Zinc Pyrithione Powder 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 class.
Zinc Pyrithione Powder is approved for over-the-counter topical use in the United States as a treatment for dandruff. It is the active ingredient in several anti-dandruff shampoos such as Head & Shoulders. However, in its industrial forms and strengths, it may be harmful by contact or ingestion.
In paint
Due to its low solubility in water (8 ppm at neutral pH), Zinc Pyrithione Powder 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 Powder is also used as an antibacterial treatment for household sponges.
