Polyvinylcaprolactam

Polyvinylcaprolactam (CAS 25189-83-7), commercially known as PVCL, is a water-soluble thermoresponsive polymer used in personal care and pharmaceutical manufacturing.

Where is Polyvinylcaprolactam used?

• Hair and skin care: rheology modifier and film-forming agent
• Pharmaceuticals: matrix polymer in drug delivery systems requiring temperature-sensitive solubility
• Textile and leather: surface modifier improving wettability, handle and coating adhesion
• Paper manufacturing: surface sizing and coating formulations with moisture management
• It exhibits a lower critical solution temperature that formulators exploit to control viscosity.

Commercial specifications

• Molecular weight ranges selected for viscosity and film-forming performance
• Pharmaceutical grade meets purity specifications for excipient qualification
