Polyvinylpyrrolidone K30 (PVP K30)


Polyvinylpyrrolidone K30 (PVP K30)

  • INCI Name:         PVP
  • Chemical Name: 1-ethenylpyrrolidin-2-one monophenyl ether
  • CAS No:               9003-39-8

PVPK30 acts as a film former and thickener. Forms hard, glossy, transparent and clear films. Produces clear formulation. Offers greater setting power and stronger adhesion. It is preferred where viscosity is critical in applications,example, pump sprays. Suitable for water based formulations. Used in skin care, oral care and hair styling applications like gels, mousses, liquid hair setting preparations etc.

●Good Solubility
It is soluble in water, but also in various organic solvents such as alcohols, carboxylic acids, amines and halogenated hydrocarbons. Solubility is limited only by its own viscosity. The ability of PVPK30 to dissolve in various organic solvents makes it widely used in the production of water treatment membranes, and it is an excellent membrane porogen.

●Surface activity
The molecule of PVPK30 is a butyrolactam structure, which has the ability of hydrophilic and polarophilic groups. There are also lipophilic. The molecular structure of PVPK30 makes it surface active and can be used as a polymer surfactant.

●Film-forming and hygroscopicity
PVPK30 can be poured or coated into a film from a solution of water, methanol, ethanol, chloroform or dichloroethane. The formed film is colorless, transparent, hard and bright, and the solvent has no effect on the formed film. PVPK30 has strong hygroscopicity, its hygroscopic ability is weaker than carboxymethyl cellulose (CMC), but stronger than polyvinyl alcohol (PVA). Once PVPK30 absorbs moisture, it will show a certain degree of cohesion. The hygroscopic equilibrium moisture content of PVPK30 is about 1/3 of the relative humidity.


PVPK30 is a polymer with high “dissolving” ability, which enables PVP to form solid complexes with many substances, especially compounds containing hydroxyl, carboxyl, amino and other active hydrogen atoms.

Uses & Applications

Personal care

Used as film-forming agent, viscosity-enhancing agent, lubricator and adhesive in hair sprays, mouses, hair-fixing gels and colution. They are also useful auxiliary materials in skin-care product, hair-dying reagent, shapoo, lipstick, deodorant, sunscreen and dentifrice.


PVP-K30 (pharmaceutical grade) is a kind of new excellent pharmaceutical excipient. It is mainly used as binder for tablet and granule, dissovlving assistant for injection, flow assistant for capsule, dispersant for liquid medicine and pigment, stabilizer for enzyme and heat-sensitive drug, co-precipitant for poorly soluble drugs, lubricator and antitoxic assistant for eye drug. PVP has been used as excipient in more than one hundred drugs.
