What is zinc Pyrithione(ZPT) ?
zinc Pyrithione(ZPT) Powder has antibacterial and anti fungal properties and is ef-fective against many pathogens. It can be used as a preservative in formula-tions, but can also be included into hair care formulations as a hair condition-ing agent that can improve the texture of hair as well as preventing and treat-ing dandruff.

Application:

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.
