Fine

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

Ceteareth-20 — an ethoxylated fatty alcohol that emulsifies oil and water in creams. Reliable workhorse with CIR safety review; the only genuine caveat is 1,4-dioxane traces, which reputable suppliers strip to negligible levels.

Skin benefits

  • Effective oil-in-water emulsifier for creams and lotions
  • Solubilises lipophilic actives for delivery
  • Good cosmetic stability and skin feel

Known concerns

  • Ethoxylated material can carry residual 1,4-dioxane unless purified
  • Mild irritation possible at higher use levels
  • Not appropriate for compromised barrier skin
