Polyvinylpyrrolidone
Chemical Name:Homopolymers of Vinylpyrrolidone
INCI Name:PVP (Polyvinylpyrrolidone)
CAS Number:9003-39-8
Properties: PVP K Series are supplied in a range of molecular weights. The products can be supplied as either aqueous solutions or powders, depending on the application requirements.
they can be characterized as film formers, but they also act as thickeners in many formulations. The higher molecular weight products being associated with greater setting power and stronger adhesion. The products are particularly suitable for water based formulations. Such as hair gels, where a high degree of clarity may be required in the finished product. The films formed by PVP tend to be hard, glossy, transparent and clear. For hair styling applications the most commonly used grades are K30,K60 and K90.

Application:
Pharmaceutical:
Povidone K30 is a new and excekkent pharmaceutical execipient.It is mainly used as binder for tablet and pellet,dissolving assistant for injection,flow assistant for capsule,dispersant for liquid medicine and pigment,stabilizer for enzyme and heat sensitive drug,coprecipitant for poorly soluble drug,lubricator and antitoxical assistant for eye drug,PVP has been used as excipients more than one hundred drugs.
Cosmetic:
PVP K products are used extensively 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.This series are particularly well suited to hair styling products,especially clear formularions. The products are supplied in a range of molecular weights allowing the formulator flexibility.The lower molecular weights such as PVP K30 are preferred where viscosity is critical in applications,example,pump sprays. The higher molecular weight products such as PVP K90 are the best choice where high viscosity and strong hold are required in applications.
Typical Examples include the following applications.
*Hair Gels
*Hair mousses
*Liquid hair setting preparations
*Pump Sprays
