PEG/PPG-22/25 COPOLYMER.

Valuable CAS - / CLEANSING, SOLVENT, SURFACTANT - CLEANSING

This block copolymer is engineered to enhance skin hydration and barrier function by increasing surface hydrophilicity and delivering moisture-retaining effects. It also possesses the characteristic ability to form micelles when introduced into aqueous solutions.

Summary

Humectant Barrier Enhancer

Science

Mechanism of Action

PEG/PPG-22/25 COPOLYMER operates by augmenting the hydrophilicity of skin surfaces, thereby contributing to an improved skin barrier. Its inherent structure allows for effective moisture retention within the skin. Additionally, this copolymer can spontaneously organize into micelles in aqueous solutions, influencing its behavior in various formulations.
