PVP:Polyvinylpyrrolidone

Chemical Profile and Overview

Polyvinylpyrrolidone (PVP), characterized by the repeating unit (C6H9NO)n, is a water-soluble polymer synthesized from the monomer N-vinylpyrrolidone. This amorphous polymer is supplied as a white to off-white, hygroscopic powder or as an aqueous solution. Renowned for its exceptional solubility, low toxicity, and outstanding film-forming and adhesive properties, PVP has established itself as a critical excipient and additive across the pharmaceutical, cosmetic, beverage, and industrial sectors. Its versatility is further enhanced by the availability of various K-values (e.g., K-15, K-25, K-30, K-90), which correlate with molecular weight and viscosity, allowing for precise selection based on application needs.

Core Advantages of PVP

1. Multifunctional Polymer Traits：Integrates film-forming, binding, dispersing and solubilizing properties, suitable for detergent, cosmetic, pharmaceutical and industrial formulations.

2. Stable & Compatible：Excellent water solubility, high compatibility with surfactants and enzymes, enhancing product stability and user experience.

3. Safe & Eco-Compliant：Non-toxic, fully compliant with EU REACH, US EPA and other international standards, aligning with global green production trends.

4. Customizable Supply：Offers products with different viscosity grades, ensures stable supply via large-scale production, supports small-batch trials and bulk purchases.
