Factory Supply CAS 9003-39-8 Polyvinylpyrrolidone PVP K30 with Competitive Price

Product Description

Polyvinylpyrrolidone is abbreviated as PVP, and is the polymer of vinylpyrrolidone. According to the different degree of polymerization, it is further classified into soluble PVP and insoluble PVPP (polyvinyl polypyrrolidone). Molecular weight of the soluble PVP is 8,**0 to *0,**0.The soluble PVP can be used as a precipitating agent which can be settle down through its action with polyphenols. Using this method, it is easily to have residual PVP in the alcohol. Due to the savings effect of PVP inside the human body, the World Health Organization doesn't recommend to apply this substance. In recent years, the use of soluble PVP has been rare. Insoluble PVPP system had began to be used in the beer industry since the early ***0s. It has a relative molecule weight greater than the relative mass greater than **0,**0. It is a insoluble polymer derived from the further cross-linking and polymerization of PVP and can be used as an adsorbent of polyphenols with a good efficacy.

PVP are used widely in a wide range in hair care, skin care & oral care products.The products are particularly suitable for formulations where viscosity modification and film forming properties are required. PVP-K products are particularly suited to hair styling products. The medium molecular weights such as PVP K*0 are preferred where viscosity is critical in applications, for example, spray. The higher molecular weight products such as PVP K*0 are the best choice where high viscosity are required in applications. PVP-K is widely used in cosmetics as followings
   *Hair Gels
   *Hair mousses
   *Liquid hair setting preparations
   *Pump Sprays
