PVP K30 Cosmetic-grade Thickening Agent and Film-forming Agent Manufacturer
INCI:Polyvinylpyrrolidone
CAS No.: 9003-39-8
Description :
PVP-K30 is a non-ionic polymer compound. It is a refined chemical product with deep research and extensive application among the N-ethyleneamine type polymers. Among them, the K value is actually a characteristic value related to the relative viscosity of the PVP aqueous solution. It has been developed into three major categories: non-ionic, cationic, and anionic; three specifications: industrial grade, pharmaceutical grade, and food grade; and a series of products with relative molecular masses ranging from several thousand to over one million, including homopolymers, copolymers, and cross-linked polymers.
