C3-11 ALKYL ACRYLATE.

Valuable / NOT REPORTED

A sophisticated lipid-soluble ester that serves as a multifunctional texture enhancer and protective agent in high-performance skincare. It is primarily utilized for its ability to create a breathable, hydrophobic film that locks in hydration while ensuring uniform application of active ingredients.

Summary

Film former Emollient Viscosity controlling Waterproofing agent

Science

Mechanism of Action

By forming a flexible and water-resistant barrier on the stratum corneum, C3-11 Alkyl Acrylate functions as both an emollient and a film-forming agent. This molecular network prevents trans-epidermal water loss (TEWL) and stabilizes UV filters or pigments, ensuring they remain evenly distributed across the skin surface for extended periods.
