zinc pyrithione usage and synthesis

product description	also known as zinc omadine ,this pyrithione complexes of zinc bromide, in the early 1930s, 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. eec and gb7916-87 provide that maximum allowable concentration of mass fraction of zinc pyrithione on cosmetics is 0.5%, only for cleaning after using products.general concentration 250 ~ 1000mg / kg (active), zinc pyrithione can be used in gels, creams, lotions, talcum powder and anti-dandruff shampoo, deodorant and also for disinfecting articles. the above information is edited by the chemicalbook of tian ye.
application	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 .
chemical properties	beige granules
usage	antibacterial (urinary)
general description	fine beige granules.
air & water reactions	insoluble in water.
reactivity profile	organometallics, such as zinc pyrithione, are reactive with many other groups. incompatible with acids and bases. organometallics are good reducing agents and therefore incompatible with oxidizing agents. often reactive with water to generate toxic or flammable gases.
fire hazard	flash point data for zinc pyrithione are not available, but zinc pyrithione is probably combustible.
