1-vinyl-2-pyrrolidone Polymer (PVP) is a white to light yellow powder or transparent granular polymer with good water solubility and alcohol solubility and stable chemical properties. Its molecular structure contains a linear pyrrolidone ring, which gives it excellent film-forming, adhesion and dispersing and solubilizing properties. It is widely used in medicine (tablet adhesives, drug coatings), cosmetics (hair gel film formers, skin care thickeners), food industry (beverage clarifiers) and industrial fields (paint dispersants).

Chemical properties

1.Molecular formula: (C₆H₉NO)n

2.Solubility: completely soluble in water, also has good solubility in most organic solvents, but partially soluble in some aliphatic hydrocarbons.

1-vinyl-2-pyrrolidone polymer Main uses

Pharmaceutical field:

Serves as a tablet binder and coating material for oral tablets. It strengthens tablet hardness, improves molding, and forms a protective coating for moisture resistance and stable storage.

Cosmetic field:

Used as a film former and thickener for hair and skin care products. It delivers long-lasting hair styling and stabilizes cosmetic formulas for better texture.

Food industry:

Acts as a beverage stabilizer and clarifier for beer, juice and tea drinks. It removes turbid impurities, prevents precipitation and prolongs shelf life.
