Regarding the uses of zinc pyridithione and copper pyridithione

It is used in dandruff-shampoo products such as Head & Shoulders and Amway products.

Mainly used in shampoos as an anti-dandruff agent

Copper pyrithione, also known as CPT or Omedin copper. English name: Copper Pyrithione. Molecular formula: C10H8N2O2S2Cu. Stability: Copper pyrithione (CPT) has high stability; when stored in a dark place, its quality remains unchanged over two years. Uses: Copper pyrithione (CPT) is primarily used in the production of products in industries such as cosmetics, adhesives, paints, coatings, paper manufacturing, pharmaceuticals, and leather processing. Quality specifications: Parameter, Appearance, Molecular weight, Content. Specifications: Green crystalline fine powder, 315.9, ≥96% (solid). Sodium pyrithionate (NPT). Quality specifications: Parameter, Appearance, Content, pH value. Specifications: Yellow to light brown transparent liquid, 40–41%, 9–11. English name: Pyrithione Sodium. Uses: Sodium pyrithionate (NPT) is currently the most effective water-soluble industrial antifungal and anticorrosive agent; it features high efficiency, broad spectrum of action, low toxicity, and stability. It can be used in metal cutting fluids, rust inhibitors, latex paints, adhesives, leather products, textile products, copper-coated paper, and other applications. Pyrithionc Zinc, also known as Omedin Zinc. English name: Pyrithionc Zinc. Molecular formula: C10H8N2O2S2Zn. Properties: Our company uses advanced technology to produce Pyrithionc Zinc in the form of fine particles, which effectively prevents precipitation and doubles the bactericidal effect. The emergence of emulsive ZPT further facilitates application development in related fields in China. Purpose: Zinc pyrithione (ZPT) has a strong fungicidal and bactericidal effect; it can effectively kill the fungi that cause dandruff, thereby reducing dandruff. It is used by many well-known brands in the shampoo industry. Zinc pyrithione (ZPT) is also widely used as a fungicide in products such as coatings and plastics. Quality indicators: Parameter, Appearance, Molecular weight, pH value. Specifications: Off-white crystalline fine powder, 316, ≥30. Appearance: White emulsion, white powder. Purity: 48–50%, ≥95%. Particle size (90% passing): 1 micron, 2 microns; (100% passing): 2 microns, 4 microns

In order to promote the long-term and healthy development of China’s pyridine industry and provide a platform for information exchange, the China Chemical Information Center has scheduled the \"2009 Symposium on the Production, Development, and Market of Pyridine and Its Derivatives\" to be held in Nanjing from June 25-26, 2009. Relevant professionals from various organizations are welcome to participate actively. Website: http://www.chemevent.com.cn/chemevent/html/article_89.html Consultation phone: 010-64426510
