We are professional high quality Polyvinylpyrroldione-k (PVP K30 K90 K15 K17 K60) factory suppliers from China, supplying USP EP grade PVP K30 series products. If you need to buy PVP K30 for cosmetic and medical purpose, please feel free to contact us, the main PVP K30 suppliers.

PVP-K30, also commenly called Polyvinylpyrrolidone, is a kind of non ionic polymer, which is the most characteristic of N- vinyl amide polymer, and has been studied deeply and widely.The different K values represent the PVP average molecular weight range. The K value is in fact the characteristic value of the relative viscosity of PVP aqueous solution, and the viscosity is the physical quantity related to the molecular weight of the polymer, so it can be used to characterize the average molecular weight of PVP by K value. The larger the value of K, the greater the viscosity, the stronger the adhesive property. 

PVP K30 is white or milky white crystalline powder. Its average molecular weight is about 40,000.

We has PVP K30 pharamceutical grade, PVP K30 cosmetic grade, PVP K30 industrial grade.

From PVP K30 application field, we can see that it can be used in three different areas:

PVP K30 Pharmaceutical application: 

- Binder for tables,capsule  

- Sugar coatings and films   

- Thickening agent 

- Solubility Improver for poorly soluble drugs 

- Bioavailability Enhancer for drug's active ingredients  

- Pore-forming for membrane products.

PVP K30 Cosmetic application:

- Film-forming agent

- Viscosity-enhancement agent, lubricator and adhesive.

- The key component of hair sprays, mousse, gels and lotions & solution, hair-dying reagent and shampoo etc. 

- Used as assistant in skin-care products, eye makeup, lipstick, deodorant, sunscreen and dentifrice.

Industrial application:

- Used as assistant in the realm of Paint and Coating, Plastics and Resin, Adhesives, Glass Fiber, Film, Ink, TV tube, Detergent, Biocide, Tabulating, Textile Dying and Printing, etc.

We also have other PVP series products, such as PVP K15 PVP K17 PVP K25 PVP K60 PVP K90 etc.
