[Apllications]
PVP K possess excellent adhesive, film-forming, dispersing and thickening properties, which are widely used in the pharmaceutical industry. They are one of the three main accessory products recognized & approved worldwide.
yellow-brown or red-brown powder, having slightly smell. It can dissolve in water and grain alcohol ,not in diethylethe or chloroform. It is a stable complex with no irritation which can sterilize bacterial, virus, fungus effectively. It is the first-selected iodine containing microbicide.
