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

A PEG/PPG ether acetate of isohexadecanol used as a surfactant and emulsifying agent in cosmetics — the ethoxylation reduces concerns about the parent fatty alcohol.

PPG-2 Isoceteth-20 Acetate is an isohexadecanol derivative with an average of 2 PO and 20 EO units, then acetylated. The ethoxylation (20 EO) significantly reduces any concerns about the fatty alcohol component. It functions as a surfactant/emulsifier in EU cosmetics and is listed in CosIng without restrictions. PEGylated ingredients have been subject to some regulatory scrutiny regarding ethylene oxide contamination (which can form 1,4-dioxane), but properly manufactured product is safe. No significant irritation or sensitisation at normal use levels.

Skin benefits

  • Emulsifying and surfactant
  • Improves product texture and feel

Known concerns

  • Potential trace 1,4-dioxane if poorly manufactured
  • PEG controversy in clean beauty circles — not a regulatory concern
