CETOLETH-6.

Valuable CAS 68155-01-1 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A high-performance non-ionic surfactant and polyether derived from cetyl and oleyl alcohols, designed to bridge the gap between oil and water phases. It is primarily utilized in precision skincare to ensure formula stability while simultaneously providing emollient benefits that enhance the skin's tactile finish.

Surfactant Emulsifying Agent Skin-Conditioning Emollient Cleansing Agent

Science

Mechanism of Action

Functioning through its amphiphilic structure, Cetoleth-6 reduces interfacial tension with a Hydrophilic-Lipophilic Balance (HLB) of approximately 10-11. This specific balance allows it to stabilize oil-in-water (O/W) emulsions effectively, while its fatty alcohol backbone acts as a skin-conditioning agent to improve product spreadability and skin softness.
