Cross Providone（PVPP）

Characteristics: Cross povidone is often called as crosslinked PVP, or insoluble PVP. It appears as white or light yellow, free flowing hygroscopic powder, odorless or with faint characteristic odor. It is insoluble in water, alkali acid and common organic solvents. It has strong swellability and can complex with polyphenols, carboxylic acid and other compounds with low-molecular weight.
