Product Name: Polyvinylpyrrolidone (PVP)
Brand: Xiaowei
Packaging: Bottle + aluminum-plastic bag
PVP is readily soluble in water, alcohols, amines, and halogenated hydrocarbons, but insoluble in acetone, ether, and other substances.
It exhibits excellent solubility, biocompatibility, physiological inertness, film-forming properties, film-protective properties, and the ability to complex with a variety of organic and inorganic compounds. It is also relatively stable to acids, salts, and heat, resulting in a wide range of applications.
It is used to absorb phenols and tannic acid from aqueous extracts to purify plant enzymes. It is also used as a chromatographic adsorbent for the separation of aromatic acids, aldehydes, and phenols.
