Polyvinylpyrrolidone PVP K12, with lowest K value among series PVP products, is a type of multifunctional water-soluble polymer material due to its low molecular weight, high water solubility, as well as excellent film-forming, dispersing, and compatibility properties. Its core applications cover the fields of medicine, daily chemicals, food, and industry.

In pharmaceutical, PVP K12 usually play the role of pharmaceutical excipients. As a co-solvent/dispersant, they are used in oral suspensions, injections and other preparations of poorly soluble drugs, significantly enhancing the solubility of drugs and the stability of the system. It can also be used as a tablet binder. Due to its low molecular weight and moderate bonding strength, it is suitable for the preparation of small-sized and easily disintegrating tablets.

It serves as a thickener/suspending agent in ointments, gels, and eye drops, improving the rheological properties of the preparations, prolonging the retention time of the drug at the administration site, and enhancing bioavailability. It is also a kind of coating auxiliary materials. As an auxiliary film-forming agent for film coating, it enhances the flexibility and adhesion of the coating film, and is particularly suitable for the coating process of small-particle microspheres.

In daily cosmetics, PVP K12 is regarded as a moisturizer in skin care products and a film-forming agent/dispersant in hair care products (hair gel, conditioner), it can form a thin protective film on the surface of hair, reduce damage to the cuticles, and improve smoothness. It can also improve the stability of the face cream and lotion system and prevent the ingredients from stratifying. As a thickener/co-solvent in toothpaste and mouthwash, it helps active ingredients such as fluoride to disperse evenly, while optimizing the taste and user experience of the products.

In industrial field, PVP K12 also has wide application.

Coatings/inks: As a dispersant/leveling agent, it is added to water-based coatings and ink systems to reduce viscosity, enhance the dispersion effect of pigments, and improve the flatness and gloss of the coating film/printed matter.

Electronic materials: It serves as a dispersant/binder in electronic pastes and photoresists, facilitating the uniform dispersion of nano-powders such as silver powder and ceramic powder, and enhancing the printing performance of pastes and the quality of film formation.

Water treatment: As a flocculation aid, it is used in combination with flocculants to enhance the flocculation effect of suspended solids in low-concentration wastewater and improve treatment efficiency.

Polyvinylpyrrolidone PVP K12, with its low molecular weight, high water solubility, and excellent film-forming, dispersing, and compatibility properties, has core applications in the fields of medicine (solubilizer, adhesive, etc.), daily chemicals (humectant, film-forming agent, etc.), and industry (dispersant, leveling agent, etc.). Unilong can supply PVP K12 with high quality and competitive price.
