pvp-polyvinylpyrrolidone function

Polyvinylpyrrolidone (PVP) is an important fine chemical product with excellent performance and high added value. Its molecules contain more polar lactam groups and have the ability of polophilic groups. It is soluble in water and alcohol, carboxylic acid, alkanol, halogenated hydrocarbons and other polar organic solvents. PVP can be formed in water, methanol, ethanol, chloroform or dichloroethane, and the film formed is colorless, transparent, hard and bright.
PVP has strong hygroscopicity and good compatibility with polyethylene, polypropylene, polyvinyl chloride, polyvinyl alcohol, shellac and dextrin.

Polyvinylpyrrolidone is a binder, emulsifier stabilizer and film forming agent.
The function of polyvinylpyrrolidone
Polyvinylpyrrolidone (PVP) is a versatile chemical 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 for whitening teeth (Wikipedia).

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.
