Cetearyl Olivate
Olive-derived emulsifier
No meaningful concern for most people; irritation is possible but rare.
What it is
Cetearyl olivate is an ester of cetearyl alcohol and the fatty acids of olive oil. It is sold as a blend with sorbitan olivate under the trade name Olivem 1000 and similar, and is popular in natural-positioned creams because it produces liquid-crystal emulsions with a light, skin-like finish.
What it does well
Creates soft, skin-friendly creams from a plant source
The olivate pair forms liquid-crystalline structures that resemble the lipid arrangement of the skin barrier, which formulators associate with a comfortable, non-greasy after-feel.
