Jul 19, 2023 · Povidone k30 has the molecular formula of (C6H9NO)n and appears as a white to slightly off-white powder. Povidone formulations are widely used in the pharmaceutical industry due to their ability to dissolve in both water and oil solvents.
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
Povidone-iodine is a water-soluble complex that mediates a bactericidal or virucidal action following the gradual liberation of free iodine from the complex at the application site to react with the pathogen.
Jul 6, 2018 · Povidone-iodine is a water-soluble complex that mediates a bactericidal or virucidal action following the gradual liberation of free iodine from the complex at the application site to react with the pathogen 1.
The different types of Povidone are characterized by their viscosity in aqueous solution, relative to that of water, expressed as a K-value. (See the section on K-value below.) The K-value of Povidone having a stated (nominal) K-value of 15 or less is not less than 85.0 percent and not more than 115.0 percent of the stated values.
Polyvinylpyrrolidone (PVP), also commercially known as K30, is a water soluble polymer. It has a hygroscopic nature with good adhesive properties. It has a stable pH and has the ability to form transparent films.
Povidone, also known as polyvinylpyrrolidone (PVP) or polyvidone, is a synthetic water-soluble polymer made from the monomer N-vinylpyrrolidone used as a binder in many pharmaceutical tablets and lubricant in eye drops.
DEFINITION. Povidone is a chain polymer of 1-vinyl-2-pyrrolidone. It contains NLT 11.5% and NMT 12.8% of nitrogen (N: 14.01), calculated on the anhydrous basis. It has the nominal K-value of NLT 10 and NMT 120. The nominal K- value is shown on the label. IDENTIFICATION. Change to read: • A. INFRAREDABSORPTIONá197Kñ Sample: Dry at 105° for 6 h.
Dec 1, 2020 · Polyvinylpyrrolidone (PVP) is a water-soluble polymer obtained by polymerization of monomer N -vinylpyrrolidone. PVP is an inert, non-toxic, temperature-resistant, pH-stable, biocompatible, biodegradable polymer that helps to encapsulate and cater both hydrophilic and lipophilic drugs.
Povidone (povidone iodine) is a topical, broad-spectrum, germicidal agent effective against a wide range of bacteria, viruses, fungi, protozoa, and spores. Because organisms do not readily develop resistance to iodine, povidone is a particularly effective antiseptic.
