Hence, it is useful in a variety of applications such as cosmetics, tissue engineering, and biomedical engineering. PVP is available in a variety of molecular weights. with the smaller molecular weights capable of binding to proteins. For use with proteins, it is recommended to start with 2-4% 40KD PVP. Depending on the specific phenolics in the plant tissue, the molecular weight of PVP will need to be optimized.

POLYVINYLPYRROLIDONE is a polymeric material and probably has low reactivity. It reacts as a weak base. PVP; PVP 1230; PVP 25; PVP 40; PVP 5; PVP 50; PVP-K 120 Polyvinylpyrrolidone (PVP) Polyvinylpyrrolidone (PVP) of average molecular weight (360,000) has been used for the intracytoplasmic sperm injection (ICSI) procedure to decrease the motility of spermatozoa, prevent their sticking to the injection pipette during the procedure, and to give more control over the flow of fluid in the ICSI needle (Palermo G et al., Fertil Steril., Poly(vinyl pyrrolidone)–iodine complex (PVP-I) and PVP-I/PEO have been electrospun into nanofibres for wound dressing applications because this polymer complex exhibits a broad range of microbicidal activity against bacteria, fungi, protozoa and viruses. slow release of iodine from the PVP-I complex in solution minimises iodine toxicity Synonyms: 1-Ethenyl-2 Pyrrolidinone Homopolymer; PVP Company Identification: Fisher Scientific One Reagent Lane Fair Lawn, NJ 07410 For information in the US, call: 201-796-7100 Emergency Number US: 201-796-7100 CHEMTREC Phone Number, US: 800-424-9300 Section 2 - Composition, Information on Ingredients ----- In the present study, we investigated the cytoprotective effects of polyvinylpyrrolidone-entrapped fullerene (C 60 /PVP), a water-soluble ROS scavenger, against nitric oxide (NO ·) and peroxynitrite (ONOO-)-induced human keratinocyte injuries. PVP polymers are available in several viscosity grades, ranging from low to high molecular weight. This range, coupled with solubility in aqueous and organic solvent systems combined with its nontoxic character, are some of the properties that gives PVP polymers great flexibility across multiple applications.

It is soluble in water, ethanol, and chloroform and is insoluble in ether (USP 1975; Budavari 1989). PVP is defined by its viscosity in aqueous solution, relative to that of water.
