Superiority:
ZPT is also called the pyridine zinc sulfide ketone, pyrazole sulfur Weng zinc, Mr Maidin zinc, the zinc complexes in the early 1930 s was synthesized and used as a topical antifungal agent or antimicrobial agent. Under normal temperature for white to yellow Crystalline powder. A slight characteristic odour. Does not dissolve in water. Its solubility: water 15 mg/kg; PH = 8 water 35 mg/kg; Ethanol is 100 mg/kg; Polyethylene glycol (PEG400) 2000 mg/kg. The best use of pH range of 4.5 ~ 9.5; The mass fraction of 10% suspension pH3.6. Pyrazole zinc sulfide with cationic and nonionic surfactant to form insoluble sediments, light and oxidant is not stable, relatively high resistance to acid and alkali is not stable. It do not compatibility with EDTA, non-ionic surfactant will make it part of the deactivation. In heavy metal chelate happens or the chelation, and the chelate poorly soluble in water. EEC cosmetics and GB7916-87 the maximum allowable concentration of the zinc pyrazole sulfur in mass fraction is 0.5%, is only used to wash after using the product. Use a concentration of 250 ~ 1000 mg/kg (actives), can be used in the gel,
