What Is PVP-I?
Pharmacopoeia Name: Copovidone
Chemical Name: Vinylpyrrolidone and Vinyl Acetate Copolymer
INCI/CTFA Name: VP/VA Copolymer
CAS Number: 25086-89-9
Properties: PVP-I is a complex of PVP and iodine, which has a strong killing effect on bacteria, viruses, fungi, molds and spores, and is stable, non-irritating and completely water-soluble.
Application
Mainly used for skin disinfection and equipment disinfection such as hospital surgery and injection, as well as oral cavity, gynecology, surgery, dermatology and other infection prevention, household utensils, utensils and other sterilization and disinfection, food industry, aquaculture industry for sterilization and disinfection and animal disease prevention, etc., is the first choice of iodine-containing medical fungicides and health and epidemic prevention disinfectants at home and abroad.
Povidone, also known as polyvinylpyrrolidone (PVP), is a water-soluble polymer used as an excipientin pharmaceuticals, cosmetics, and food products. Povidone is classified based on its molecularweight, ranging from low to high. Low molecular weight povidone (LMW-PVP) is typically used as abinder, while high molecular weight povidone (HMW-PVP) is used as a thickener and adhesive.Intermediate molecular weight povidone (IMW-PVP) is commonly used as a stabilizer and solubilizerin pharmaceutical formulations. In addition to molecular weight, povidone can be further classifiedbased on its degree of crosslinking. Crosslinked povidone (crospovidone) is insoluble in water and isused as a disintegrant in tablets, while uncrosslinked povidone (non-crospovidone) is used as asolubilizer and emulsifier. Other variations of povidone include povidone iodine, which has antisepticproperties, and copovidone, a copolymer of povidone and vinyl acetate used as a binder anddisintegrant. Overall, the versatility and variety of povidone classifications make it a widely-usedexcipient in the pharmaceutical industry.
