What Is PVP K-Series?

The full name of PVP is polyvinylpyrrolidone, which is produced by the polymerization of N-vinylpyrrolidone (NVP). It is a non-ionic polymer compound.

PVP was invented by BASF in 1938. Because it is a polymer that is physiologically similar to human plasma proteins, it was once used as a substitute for plasma during World War II. PVP has the advantages of excellent solubility, chemical stability, low toxicity, and film-forming properties. It has a high demand for applications as an auxiliary, additive, and auxiliary material. It is a widely used fine chemical product in medicine, textiles, chemicals, and beverages. It has applications in many fields such as , daily chemicals and so on.

PVP K-series has different K value including PVP K12, K15, K25, K30, K60, K90, K120. As a polymer, it has wide application in the world.

Food industry. PVP can be used as a stabilizer, thickener and taste improver in food, such as in yogurt, beverages and ice cream, to improve the taste, appearance and preservation of food.

Pharmaceutical industry. PVP is widely used in the pharmaceutical field due to its excellent solubility, biocompatibility and chemical stability. It can be used as pharmaceutical excipients, pharmaceutical carriers, sustained-release agents and pharmaceutical synthesis intermediates.

Daily cosmetics. PVP has good dispersion and film-forming properties and can be used in cosmetics such as styling liquid, hair conditioner, shampoo, cream, and sunscreen to enhance the moistening and lubricating effects.

Textile and dye industry. PVP has affinity with many organic dyes and can be used to improve dyeing power and hydrophilicity.

Detergent. PVP has anti-soil redeposition properties and can be used to prepare clear liquids or heavy-duty detergents to prevent skin irritation from synthetic detergents.

Paints and Pigments. PVP can increase the gloss and dispersion of coatings and pigments, and improve thermal stability.

Polymer Technology. PVP can be used as a polymer surfactant and as a dispersant, emulsifier, thickener, etc. in different dispersion systems.

Medical hygiene. PVP is also used in the medical and health fields, such as contact lens care solutions, disinfectants and antiseptics, etc.

In addition, PVP can also be used in other fields, such as textiles, food processing, daily cosmetics, detergents, coatings, polymer technology, medical and health care and other fields.
