Introduction of main characteristics of pyrithione salts zinc pyrithione
As a kind of pyrithione salts, zinc pyrithione is also called zinc pyrithione, zinc pyrithione, and zinc omepramine. This zinc complex was synthesized and used as a topical antifungal agent in the 1930s. Or an antibacterial agent. It is a white to yellow crystalline powder at room temperature, slightly characteristic odor, and insoluble in water.
In use, it is generally preferred to use zinc pyrithione pyrithione salts at a pH between 4.5 and 9.5. With a mass fraction of 10% and a suspension pH of 3.6, zinc pyrithione forms insoluble precipitates with cationic and nonionic surfactants, is unstable to light and oxidants, and is unstable to acids and bases at higher temperatures.
When zinc pyrithione pyrithione salt is present in heavy metals, chelation or de-chelation will occur, and these chelate compounds are often poorly soluble in water. A concentration of 250 ~ 1000mg / kg (active), can be used in gels, creams, lotions, powder and anti-dandruff shampoo, also used in deodorant and disinfection products. In summary, zinc pyrithione is a chelate which is a very effective anti-mildew and anti-bacterial compound.http://china-zhufengchem.com/
