Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A mixed ethoxylated and propoxylated cetearyl alcohol used as a mild surfactant and emulsifier in lotions and cleansers. It is generally well-tolerated but, like all ethoxylates, depends on supplier purity controls.

Skin benefits

  • Mild nonionic surfactant and emulsifier
  • Solubilizes fragrance and oils into aqueous systems
  • Low irritation profile on intact skin
  • Stable across a wide pH range

Known concerns

  • Ethoxylated/propoxylated chain may carry 1,4-dioxane traces
  • Penetration enhancer behaviour for other ingredients
  • Not biodegradable as readily as natural surfactants
  • Quality depends on manufacturer purification
