PEG-135/VA/VINYL CAPROLACTAM COPOLYMER.

Valuable / SURFACTANT - CLEANSING

PEG-135/VA/VINYL CAPROLACTAM COPOLYMER is a versatile, amphiphilic polymer that primarily functions as a film-forming and skin-conditioning agent. Its unique composition contributes to high solubility in both water and organic solvents, making it a valuable ingredient for enhancing formulation stability and texture. This copolymer can also serve as a thickening or gelling agent.

Science

Mechanism of Action

This copolymer forms flexible and durable films on the skin, which contributes to a smoother tactile sensation, particularly in leave-on formulations. Its amphiphilic nature allows it to effectively interact with both aqueous and oil phases within a product, providing stability to emulsions and adjusting viscosity by acting as a thickening or gelling agent.

Stability

Copolymers containing N-vinylcaprolactam may exhibit thermosensitive and pH-dependent behavior. Aggregation has been observed in acidic environments at room temperature and in alkaline conditions at elevated temperatures. Specifically, transparency is maintained at pH 4.5, but aggregation can occur at pH 9.8 and 25°C.
