China Supply Pvpi / Povidone Iodine CAS 25655-41-8 for Anti-Microbial
PVP-I is an unstable complex formed by the complexation of surfactants with iodine, belonging to the category of iodophor external disinfectants. It is a yellow brown to reddish brown amorphous powder at room temperature, easily soluble in water or ethanol, and insoluble in ether . The 1-vinyl-2-pyrrolidone homopolymer is a surfactant that helps to wet and penetrate objects in solution, thereby enhancing the bactericidal effect of iodine. Among them, 80-90% of bound iodine can be depolymerized into free iodine, with high concentration, strong bactericidal effect, odorless, non irritating, non allergenic, and low toxicity. It is a broad-spectrum fungicide that can kill viruses, bacteria, spores, fungi, and protozoa.

Povidone-iodine (PVP-I), brand name Wokadine, Pyodine, and Betadine is a stable chemical complex of polyvinylpyrrolidone (povidone, PVP) and elemental iodine. It contains from 9.0% to 12.0% available iodine, calculated on a dry basis.
This unique complex was discovered in 1955 at the Industrial Toxicology Laboratories in Philadelphia by H. A. Shelanski and M. V. Shelanski. They carried out tests in vitro to demonstrate anti-bacterial activity, and found that the complex was less toxic in mice than tincture of iodine.
Human clinical trials showed the product to be superior to other iodine formulations.
Betadine was immediately marketed, and has since become the universally preferred iodine antiseptic.
It is on the WHO Model List of Essential Medicines, the most important products needed in a basic health system.
