N-Vinyl-2-pyrrolidone(NVP) is an organic compound with the formula C6H9NO. It is a colorless liquid that evaporates at room temperature. NVP is a compound containing a pyrrole ring, and its vinyl-starting reaction is relatively easy compared to other pyrrole compounds. Because of its special chemical properties, NVP is widely used in polymers, drugs and cosmetics. NVP easily soluble in water or various other organic solvents. NVP has active chemical properties and is easy to hydrolyze and polymerize.


We are professional manufacturer of NVP in China, engaged in the R&D, production and sales of NVP and series downstream chemical materials like PVP. Unilong Industry Co., Ltd. can supply high quality and OEM order to meet your application.

N-Vinyl-2-pyrrolidone is a compound with important uses. Due to its hydrophilicity, strong polarity, low toxicity and cationic activity, it can be widely used in industrial fields such as adhesives, coatings, textiles, food and pharmaceuticals. Its copolymer has good film strength, dyeing compatibility, rigidity and viscosity. NVP is widely used in cosmetics, washing products, medicine, photosensitive materials and other fields.

Pharmaceutical field :NVP is a widely used drug monomer that can be used to prepare a variety of synthetic drugs. For example, NVP can be copolymerized with other monomers to produce a heat-sensitive hydrogel, which can be used in medical products such as wrapping hot packs and heat patches. In addition, NVP can also be used with other biomedical materials to prepare highly biocompatible and bioactive composite materials.

Cosmetics :NVP can be used to prepare various oil-water emulsion, foaming agent, gel and other cosmetic products. In particular, the copolymerization of NVP with amino silicone oil, silane, disuccinate, etc., can prepare a polymer with efficient moisturizing function, which is widely used in skin care products, makeup and other cosmetic fields.

NVP is also often used to produce homopolymers and copolymers that require good molding, such as polyvinylpyrrolidine series products.


Features and Benefits

NVP is the raw material of PVP. N-vinylpyrrolidone has active chemical properties and is easily hydrolyzed and polymerized. Usually, NaOH or TMHPO is added as a polymerization inhibitor of the product during storage and transportation.
