Zinc Pyrithione is a coordination complex of zinc. It has fungistatic (that is, it inhibits the division of fungal cells) and bacteriostatic (inhibits bacterial cell division) properties and is used in the treatment of seborrhoeic dermatitis.

Function

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 was already synthesized and used as a topical antifungal or antibacterial agent. At room temperature it is white to yellow crystalline powder. Slight characteristic odor. 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.

zinc pyrithione can be used in gels, creams, lotions, talcum powder and anti-dandruff shampoo, deodorant and also for disinfecting articles.

Shampoo for dandruff,zinc pyrithione can inhibit Gram positive and negative bacteria and mold growth,Care hair Effectively , delay hair aging ,control white hair and hair loss generation. zinc pyrithion is also used as a cosmetic preservative, oil, paint biocide.

Zinc pyrithione has a strong killing power on fungi and bacteria so that it can effectively kill dandruff fungus,playing a role in dandruff .
