C10-30 ALKYL METHACRYLATE.

Valuable / NOT REPORTED

An amphiphilic polymer that serves as a sophisticated rheology modifier and emulsion stabilizer in skincare formulations. This ingredient creates a three-dimensional network structure that enhances product texture while forming a breathable, non-occlusive film on skin. Its dual hydrophobic-hydrophilic nature makes it particularly effective at preventing emulsion separation while improving product spreadability.

Summary

Viscosity controlling Emulsion stabilizing Film forming Texture enhancing

Science

Mechanism of Action

Functions through water-activated swelling upon neutralization, creating a molecular network that increases viscosity and stabilizes oil-water interfaces. The polymer's amphiphilic structure allows it to trap oil droplets while forming a permeable film layer that enhances sensory properties without occluding skin.
