Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group.It is a colorless liquid although commercial samples can appear yellowish.
Polyvinylpolypyrrolidone (polyvinyl polypyrrolidone, PVPP, crospovidone, crospolividone, or E1202) is a highly cross-linked modification of polyvinylpyrrolidone (PVP).. The cross-linked form of PVP is used as a disintegrant (see also excipients) in pharmaceutical tablets. [1]

Povidone-iodine (PVP-I), also known as iodopovidone, is an antiseptic used for skin disinfection before and after surgery. [ 1 ] [ 2 ] It may be used both to disinfect the hands of healthcare providers and the skin of the person they are caring for. [ 2 ]
USAID delivers billions of dollars in humanitarian aid, funding that advocates say provides a critical lifeline to more than 100 countries at only a small fraction of the overall federal budget.
Percoll itself specifically consists of polydisperse silica nanoparticles 15–30 nm diameter (23% w/w in water) which have been coated with polyvinylpyrrolidone (PVP). Percoll is well suited for density gradient experiments because it possesses a low viscosity compared to alternatives, a low osmolarity , and no toxicity towards cells and their ...
