Ceteareth-6 is a non-ionic emulsifier and surfactant derived from cetearyl alcohol and 6 moles of ethylene oxide. It excels at creating stable oil-in-water emulsions with smooth, light textures. It is widely used in facial creams, body lotions, sunscreens and cleansing milks. It ensures uniform distribution of oils and actives while improving spreadability. Its proven compatibility and cost-effectiveness make it a workhorse ingredient in both mass-market and mid-range formulations.
What is CETEARETH-6 used for?
- Emulsifying: Forms stable O/W emulsions with creamy consistency. Essential in moisturizers, day creams and SPF products.
- Surfactant/Cleansing: Gently lifts dirt and makeup in rinse-off systems. Common in creamy cleansers and makeup removers.
- Dispersing agent: Helps incorporate pigments and powders evenly. Frequently found in foundations and tinted moisturizers.
Origin
Ceteareth-6 is produced by ethoxylating cetearyl alcohol, which is a blend of cetyl and stearyl alcohols sourced from coconut or palm kernel oil. The process uses about six moles of ethylene oxide. This controlled reaction creates a waxy solid that melts near body temperature. It offers strong emulsifying performance in both hot and cold processes.

CLEANSINGSafety Profile
Ceteareth-6 is considered safe for cosmetic use at typical levels of 0.5 to 10%. It carries a low hazard rating (EWG 1–3 depending on purity). Modern grades contain very low levels of 1,4-dioxane and residual ethylene oxide, well below regulatory limits. It is non-irritating to skin and eyes in final formulations. Approved by EU COSING and compliant with global standards for leave-on and rinse-off applications.
