CETETH-10 STEARATE.

Valuable / SKIN CONDITIONING

A sophisticated non-ionic emulsifier and skin-conditioning agent that bridges the gap between oil and water phases to create stable, elegant textures. It simultaneously acts as a lightweight occlusive, forming a breathable barrier that prevents trans-epidermal water loss without a heavy residue.

Summary

emulsifying surfactant skin conditioning emulsion stabilizer

Science

Mechanism of Action

As an ethoxylated fatty acid ester, it functions by lowering the interfacial tension between aqueous and lipid components, facilitating a uniform oil-in-water (O/W) emulsion. On the skin's surface, it aligns to create a micro-thin film that reinforces the natural lipid mantle, aiding in moisture retention and improving tactile smoothness.
