C10-30 ALKYL PEG-25 METHACRYLATE.

Valuable / NOT REPORTED

A sophisticated amphiphilic polymer component that creates optical blurring effects while providing texture enhancement in skincare formulations. This multifunctional ingredient excels at minimizing the visible appearance of pores and delivering a refined, matte finish to the skin surface.

Summary

viscosity controlling emulsion stabilising film forming optical blurring texture enhancement

Science

Mechanism of Action

Acts as an associative monomer within HASE polymer networks, where its C10-30 alkyl chains form hydrophobic anchors that create three-dimensional structures. These networks provide optical diffusion properties that blur skin imperfections while simultaneously controlling product viscosity and enhancing emulsion stability.
