Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A nonionic emulsifier (cetearyl alcohol with ~30 ethylene oxide units) common in creams and lotions. Reliable workhorse, CIR-safe on intact skin; ethoxylation by-product (1,4-dioxane) stripping matters for purity.
Skin benefits
- Reliable non-ionic emulsifier
- Helps oil and water phases mix in heavier creams
- CIR-reviewed safe in intact-skin formulas
- Strong industry safety record
Known concerns
- 1,4-dioxane is a possible by-product of ethoxylation — purified grade required
- Per CIR, should not be used on damaged skin
- Aquatic toxicity moderate for ethoxylates
- Higher EO chain length = more dioxane-stripping needed
