PVP-K
Polyvinylpyrrolidone is one of the important excipients advocated internationally. PVP is a white to milky white powder. Easily soluble in water, alcohol, amines and halogenated hydrocarbons, but insoluble in acetone, ether, etc. It has excellent solubility, biocompatibility, physiological inertness, film-forming properties, film protection ability and the ability to combine various organic and inorganic compounds, and is relatively stable to acids, salts and heat. Therefore it has a wide range of uses.

PVPP
PVPP is white or off-white hygroscopic and easy-flowing powder, odorless or slightly odorless. Insoluble in water, alkali, acid and common organic solvents. It has strong swelling properties and complexing ability with polyphenols. Therefore, it is considered the first choice disintegrant for high-end tablet drugs. Especially suitable for the formulation of instant and chewable tablets.
PVP-I
PVP-I is a complex of PVP and iodine, which is in the form of brown-yellow or brown-red powder, with a light special smell. Soluble in water and ethanol, insoluble in diethyl ether and chloroform. It has good stability, no irritation, and has strong killing effect on bacteria, viruses, fungi, molds and spores. It is the preferred iodine-containing fungicide.

NOP
NOP, also known as 1-octyl-2-pyrrolidone/N-Octyl pyrrolidone, is a highly efficient and selective solvent that can be used in the recovery of organic raw materials, the refining of lubricants, and the solvent for polymers and polymerization reactions. It is also widely used in the synthesis reactions of fine chemicals such as pharmaceuticals, pesticides, pigments, flavors, and cleaning agents. application.
PVPSH
PVPSH is M-vinylpyrrolidone polymer. It is colorless or light yellow transparent liquid, neutral, miscible with water, ethanol, etc., It is a dispersant with excellent performance. It is a special dispersant used when fluorescent whitening powder is turned into slurry in the printing and dyeing industry.
PVPS2
PVPS2 is a compound of PVP. It is a light yellow transparent liquid. Miscible with water. It can effectively prevent printed or different-colored fabrics from being recontaminated and changed color during the desizing and washing process, and greatly improve the whiteness and brightness of the fabric.
PVPQ
PVP-Q is a quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate. It is a viscous colorless or slightly yellow clear aqueous solution, odorless or with a slight characteristic smell. It is mainly used in hair care products as polish, film former and softener.
