Polyvinylpolypyrrolidone is a polymer of vinyl pyrrolidone.
Polyvinylpolypyrrolidone is divided based on degree of polymerization into soluble PVP and insoluble polyvinyl polypyrrolidone (PVPP).
Commercially available Polyvinylpolypyrrolidones are divided into four viscosity grades by K value (Fikentscher K): K-15, K-30, K-60, K-90, with respective molecular masses of 10000, 40000, 160000, and 360000.

K value or relative molecular mass is one of the important factors determining the various properties of PVP.
Polyvinylpolypyrrolidone is one of the three major new medicinal materials.
Polyvinylpolypyrrolidone can be used for tablets, granules, a cosolvent for injections, glidant for capsules, liquid preparation and dispersant for colorants, stabilizer for enzymes and thermosensitive drugs, precipitant for poorly soluble drugs, and a removal agent and lubricant for eye drops, etc.
The combination of Polyvinylpolypyrrolidone with toxins, drugs, and chemical agents can reduce their toxicity.
Complexes with iodine are very stable, with good bactericidal effects, reducing toxicity.
Used in industry as a foaming polystyrene additive, gelling agent, stabilizer, fiber treatment agent, paper processing aid, adhesive, and thickener.
Some dyes can also be strongly complexed with Polyvinylpolypyrrolidone, which is the basis for Polyvinylpolypyrrolidone as a dye bleaching agent.
Polyvinylpolypyrrolidone and its copolymer is an important raw material for cosmetics, mainly used for hair styling agents.
The film Polyvinylpolypyrrolidone forms on hair is flexible and shiny, with good combing performance, without attracting dust.
Different resins can satisfy different relative humidity and climatic conditions, so it is an indispensable raw material for styling hair cream, hair gel, and mousse.
Polyvinylpolypyrrolidone can also be used as a cosmetic skin care moisturizing agent, base material of grease, hair coloring dispersant, and foam stabilizer.
Polyvinylpolypyrrolidone can improve the consistency of shampoo.
Insoluble Polyvinylpolypyrrolidone is a stabilizer for beer, fruit juice, vinegar, wine and so on, improving its clarity, color and taste.
N-Vinyl-2-pyrrolidone is a member of pyrrolidin-2-ones.
Polyvinylpolypyrrolidone is a highly cross-linked modification of polyvinylpyrrolidone (PVP).
This cross-linked form of Polyvinylpolypyrrolidone is used as a disintegrant (see also excipients) in pharmaceutical tablets.
Polyvinylpolypyrrolidone is insoluble in water, though it still absorbs water and swells very rapidly generating a swelling force.
This property makes it useful as a disintegrant in tablets.
Polyvinylpolypyrrolidone can be used as a drug, taken as a tablet or suspension to absorb compounds (so-called endotoxins) that cause diarrhea. (Cf. bone char, charcoal.)
Polyvinylpolypyrrolidone is also used as a fining to extract impurities (via agglomeration followed by filtration).
Polyvinylpolypyrrolidone is used in winemaking.
Using the same principle Polyvinylpolypyrrolidone is used to remove polyphenols in beer production and thus clear beers with stable foam are produced.
One such commercial product is called Polyclar.
Polyvinylpolypyrrolidone forms bonds similar to peptidic bonds in protein (especially, like proline residues) and that is why it can precipitate tannins the same way as proteins do.
Polyvinylpolypyrrolidone is used as a stabiliser.
Polyvinylpolypyrrolidone cross-linked, commonly referred to as cross-linked polyvinylpyrrolidone (PVP), is a synthetic polymer known for its versatile applications in various fields, including pharmaceuticals, cosmetics, and food industries.
Polyvinylpolypyrrolidone is characterized by its high molecular weight and cross-linked structure, which enhances its stability and solubility in water.
Polyvinylpolypyrrolidone exhibits excellent binding properties, making it an effective excipient in tablet formulations and a stabilizer in emulsions and suspensions.
Additionally, Polyvinylpolypyrrolidone possesses film-forming capabilities, which contribute to its use in cosmetic products for hair and skin.
The polymer is generally regarded as non-toxic and biocompatible, which further supports its use in medical applications, such as drug delivery systems.
Polyvinylpolypyrrolidone's ability to form gels and its hygroscopic nature allow it to retain moisture, making it beneficial in formulations requiring hydration.
Overall, cross-linked polyvinylpyrrolidone is valued for its multifunctionality, safety profile, and effectiveness in enhancing the performance of various products.
Polyvinylpolypyrrolidone is a cross-linked polymer that ispolymerized from vinyl pyrrolidone monomer under specific conditions and is insoluble in water, strong acids, strong bases and general organic solvents.
As an important polymer fine chemical product, Polyvinylpolypyrrolidone has manyexcellent and unique properties and has been widely used in cosmetics, food,medicine and other fields.

Synthesis
Structurally, crosslinked Polyvinylpolypyrrolidone can be regarded as a crosslinked polymer formed by physical or chemical crosslinking of polyvinylpyrrolidone (PVP) molecular chains with a linear molecular structure.
Commonly used cross-linking methods include N-vinylpyrrolidone (NVP) cross-linking, NVP self-cross-linking polymerization (bracts polymerization), and cross-linking copolymerization of compounds with multiple unsaturated groups (e.g., difunctional cross-linking agents) with NVP. Commonly used in the polymerization of crosslinking agent is mainly hydrocarbon bisacryloyl amine (such as N, N-methylene bisacrylamide, etc.), divinyl aromatic compounds (such as divinylbenzene, divinyl ethylbenzene, etc.).
