Product Details

Polyvinylpyrrolidone (PVP) is a polymer of vinyl pyrrolidone. It is divided based on degree of polymerization into soluble PVP and insoluble polyvinyl polypyrrolidone (PVPP). Commercially available PVPs are divided into four viscosity grades by K value (Fikentscher K): K-15, K-30, K-60, K-90, with respective molecular masses of 10000, 40000, 160000, and 360000. K value or relative molecular mass is one of the important factors determining the various properties of PVP.

Product Application Of Crospovidone CAS#25249-54-1

PVP (polyvinylpyrrolidone) is a chemical ingredient that, depending on the formulatory requirement, can act as a binder, viscosity controller, emulsion stabilizer, or film former. Its benefits include water and wear resistance, pigment dispersion, a non-greasy feel, and improved stick integrity. PVP is commonly found in waterproof sunscreens, mascaras, and lipsticks in order to improve their wear.
