Product Introduction
Copovidonum25086-89-9 (CAS 25086-89-9) is a vinylpyrrolidone-vinyl acetate copolymer (60:40 ratio) meeting Ph.Eur/USP-NF standards. This pharmacopeial polymer (K-value 25-35) functions as solubility enhancer and tablet binder in solid dosage formulations.
Povidone VA64 is generally considered safe for use in pharmaceutical and cosmetic applications, with no known toxicological effects. In fact, it is often used as a replacement for other excipients, such as polyethylene glycol, which have been shown to have potential toxic effects. It is also biocompatible, meaning that it does not cause a significant immune response in the body.
Overall, Povidone VA64 is a versatile excipient that has many applications in various industries. Its unique properties make it an ideal choice for tablet formulations, coatings, and a range of other applications. As technology and research continue to improve, we can expect to see even more applications for Povidone VA64 in the future.
