Polyvinylcaprolactam

Polyvinylcaprolactam (CAS 25189-83-7), commercially known as PVCL, is a water-soluble thermoresponsive polymer used across personal care and pharmaceutical manufacturing. It exhibits a lower critical solution temperature that formulators exploit to control viscosity.

This unique property allows for precise control over film formation and moisture retention in finished products. In hair care and skin care formulations, PVCL functions as a rheology modifier and film-forming agent.

It contributes significantly to hold, texture, and the controlled release of active ingredients. Pharmaceutical manufacturers use it as a matrix polymer in drug delivery systems where temperature-sensitive solubility is required.

Its application supports controlled-release tablet and hydrogel formats effectively. Textile and leather processors apply it as a surface modifier to improve wettability, handle, and coating adhesion on treated substrates.

In paper manufacturing, it supports surface sizing and coating formulations where moisture management is essential. Film integrity is critical to end-product performance in these industrial applications.

Polyvinylcaprolactam is supplied as a white to off-white powder. It is available in technical and cosmetic grades, with molecular weight ranges selected to match specific viscosity and film-forming performance targets.

Pharmaceutical-grade material is sourced to meet relevant purity specifications required for excipient qualification. This ensures the material meets the rigorous demands of modern chemical manufacturing and formulation.
