C12-14 PARETH-3.

Valuable CAS 68439-50-9 (generic) / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A non-ionic surfactant and emulsifier that creates stable oil-water mixtures while enhancing the penetration of other skincare ingredients. This ethoxylated alcohol derivative works by reducing surface tension between different phases in formulations. Its dual functionality as both an emulsion stabilizer and penetration enhancer makes it valuable in complex skincare formulations.

Summary

Emulsifying Surfactant/cleansing Emulsion stabilizing Penetration enhancer

Science

Mechanism of Action

Functions as a non-ionic surfactant that reduces interfacial tension between oil and water phases to create stable emulsions. Additionally acts as a penetration enhancer by temporarily modifying the lipid bilayer structure of the stratum corneum, facilitating improved absorption of accompanying active ingredients.
