Sodium Pyrithione 40%
Sinobio
29333990
Sodium Pyrithione (SPT), CAS number 3811-73-2, is an important organic compound with extensive industrial applications and biological activity. The following is a detailed introduction to it:
- Molecular Formula: C₅H₄NOSNa
- Molecular Weight: 149.14 (alternatively reported as 151.16, possibly due to differences in molecular formula notation)
-Appearance: The pure compound is a white or off-white powder, soluble in water and organic solvents such as ethanol. It is typically formulated as a 40% solution, appearing as a pale yellow to light brown transparent liquid.
-Stability: Stable under alkaline or neutral conditions; efficacy is reduced in acidic environments. Unstable when exposed to light, oxidizing agents, and strong reducing agents.
-pH Value: The pH value of a 2% aqueous solution is approximately 8.0.

*Widely used in shampoo, conditioner, and other rinse-off products, it has anti-dandruff, anti-itch, and anti-mold/antimicrobial effects.
*As a preservative, it prevents product spoilage and mold growth, extending shelf life.
*Building Coatings: Used as a mold inhibitor to prevent mold growth during storage and use.
*Adhesives and Sealants: Inhibits microbial growth, enhancing product stability and durability.
*Metalworking Fluids: Acts as a biocide to control bacteria and fungi in cutting fluids and coolants, preventing degradation and odor.
*Textiles and leather products: Prevents mold growth on fibers and leather in humid environments, maintaining product appearance and performance.
*As a fungicide, used for disease control in crops such as fruit trees, peanuts, cereals, and vegetables.
*An excellent disinfectant for silkworm farming, ensuring hygiene and safety in sericulture.
*Used to formulate disinfectants, antiseptics, and broad-spectrum antifungal dermatological medications for the treatment of skin fungal infections and other conditions.
*Sodium Pyrithione is widely used in many fields, including medicine, daily chemicals, metal processing, agricultural products, anti-corrosion coatings, leather products, textiles, paper, and bamboo, wood, rattan, and grass products.
*In the medical and chemical industry, it is used in various antifungal drugs and shampoo and skin care products. In the agricultural sector, it is used as a fungicide for fruit trees, peanuts, cereals, vegetables, and other crops; in the industrial sector, it is used as a mold inhibitor in building coatings, adhesives, sealants, and other products.
*Sodium Pyrithione is stable under alkaline or neutral conditions, but its effectiveness is reduced in acidic environments.
*When stored in the dark, its content remains unchanged for two years, demonstrating excellent storage stability.
Packing：1,200kg/drum, 21.6mt=1*20FCL.
Storage：Sealed in dry, room temperature. Shelf life is 1 year.
