Raw material polyvinylpyrrolidone pvp

Polyvinylpyrrolidone (PVP) is a polymer that is synthesized from the monomer vinylpyrrolidone. The production of PVP involves the polymerization of vinylpyrrolidone monomers through various methods, such as solution polymerization or precipitation polymerization. The raw material for PVP production is therefore vinylpyrrolidone.

Vinylpyrrolidone (VP) is typically derived from the reaction between 2-pyrrolidone and acetylene or by the reaction of 2-pyrrolidone with vinyl acetate followed by hydrolysis. The resulting vinylpyrrolidone monomer is then used as the building block for PVP production.

The quality and properties of PVP can be influenced by the choice of raw materials, the polymerization process, and the purification steps. Different grades of PVP may be available based on factors such as molecular weight, purity, and specific applications.

It’s worth noting that PVP can also be copolymerized with other monomers, such as vinyl acetate, vinyl alcohol, or acrylic acid, to introduce additional properties or functionalities to the polymer. These copolymers may require different raw materials in addition to vinylpyrrolidone.

vinylpyrrolidone serves as the key raw material for the production of polyvinylpyrrolidone (PVP), a widely used polymer with various applications in industries such as pharmaceuticals, cosmetics, coatings, adhesives, and more.

The invention relates to an adhesive, an emulsifier stabilizer and a film forming agent
The function of polyvinylpyrrolidone
Polyvinylpyrrolidone (PVP) is a versatile ingredient that, according to the Cosmetics Database and CosmeticsInfo.org, acts as a binder, emulsifying stabilizer, suspension, and hair styling in cosmetics and beauty products, primarily in mascara, eyeliner, conditioner, hair gel, shampoo, and other hair care products. It prevents the separation of water and oil in the emulsion and allows the ingredients in the compressed powder to bond together. Polyvinylpyrrolidone also forms a dry film on the surface of skin, nails and hair. When it becomes an ingredient in hair care products, it prevents hair from absorbing moisture and styling hair. It is also used in contact lens solutions and as a thickener in whitening toothpastes and gels that whiten teeth.
Polyvinylpyrrolidone is approved by the FDA (specifically as a clarifying agent in beer, wine and vinegar, but also as a fresh-keeping coating for citrus fruits) and is also approved by the CIR.
Safety/Side Effects
In the cosmetics database, polyvinylpyrrolidone is considered a safe ingredient and is rated as a low risk ingredient. Although the Cosmetic database points to its potential carcinogenic potential, the International Agency for Research on Cancer considers it unlikely to be a human carcinogen. According to Wikipedia, polyvinylpyrrolidone is approved as a binder for tablets because it can pass through the body when taken orally and absorbed.
