Vinylpyrrolidone-vinylamine copolymer

Vinylpyrrolidone-vinylamine copolymer (CAS 28158-56-7) is a synthetic cationic polymer combining the film-forming characteristics of vinylpyrrolidone with the reactive amine functionality of vinylamine.

Where is Vinylpyrrolidone-vinylamine copolymer used?

• Personal care: conditioning agent
• Hair care: film-forming agent improving wet combability and surface adhesion of actives
• Pharmaceuticals: binder or coating aid where controlled surface interaction is required
• Water treatment: cationic amine groups support coagulation and flocculation of suspended particles in industrial effluent processing
• Home care and industrial cleaning: rheology modification and improved surface wetting on hard surfaces
• It is used across personal care, pharmaceutical, and industrial sectors primarily for rheology modification, surface conditioning, and flocculation.

Good to know: Selection is driven by amine content, molecular weight range, and intended application. Buyers should confirm charge density and viscosity profile against their formulation requirements when evaluating supply options.
