Vinylpyrrolidone (PVP) has many roles and applications.
Polyvinylpyrrolidone is a polymer material, also known as PVP. It has the characteristics of water solubility, film forming and adhesion, and can be used in medicine, cosmetics, textile, printing, electronics and other fields. In addition, polyvinylpyrrolidone can also be mixed with other substances to play a synergistic effect, such as mixed with salicylic acid, can be used to prepare antiviral, antibacterial agents and so on.
PVP is a kind of non-ionic polymer compound, has very low toxicity and high physiological inertia, has no irritation to skin and eyes, is widely used in cosmetics. it forms a non-occlusive membrane, plays a moisturizing role, reduces greasy feeling, and gives the skin a soft and smooth feeling. In addition, PVP can speed up the penetration of facial mask ingredients, extend the retention time of ingredients, make the skin better absorb nutrients.
The role of polyvinylpyrrolidone in the field of crosslinking
Polyethylpyrrolidone can be used as a crosslinking agent. When mixed with cellulose, chitosan and other natural polymer materials, the strength and stability of the material can be improved. In addition, in the textile industry, the cross-linking of polyethylpyrrolidone with polyacrylic acid can enhance the tensile strength and washable resistance of the fiber.
Other applications of polyvinylpyrrolidone
In addition to being a crosslinker, polyvinylpyrrolidone can also be used in the following areas:
In the field of medicine, PVP also plays an important role. It can be used as a stabilizer to prolong the storage life of beverages such as beer, white wine, grape juice and fruit juice. In the pharmaceutical industry, PVP is mainly used as a disintegrant of tablets, is also used as a disintegrant and filler of pills, granules and hard capsules. PVP has excellent adhesion due to its excellent fluidity and plastic deformation, is helpful to improve the solubility and bioavailability of the drug, improves the taste of the drug, has the effects of resisting diarrhea, gastritis, ulcer and so on.
PVP also has excellent biocompatibility, has no irritation to skin, mucosa and eyes, itself is not carcinogenic, has good food safety. In food processing, PVP is mainly used as a clarifying agent and stabilizer for beer, juice, wine and other food.
PVP uses include as an emollient moisturizer in cosmetics, as a stabilizer and disintegrator in the pharmaceutical field, and as a clarifying agent and stabilizer in food processing.
