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

Octyldodeceth-30 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Octyldodeceth-30 is an ethoxylated ether of 2-octyldodecanol with an average of 30 moles of ethylene oxide per molecule. The high EO degree raises its HLB to approximately 17, making it a hydrophilic emulsifier suitable for O/W systems. The branched 2-octyldodecyl group provides emolliency while the long PEG chain minimizes skin penetration and irritation. EU Cosmetics Regulation permits its use without specific restriction. It is not classified as a skin sensitizer and presents very low irritation risk at cosmetic concentrations.

Skin benefits

  • Hydrophilic emulsifier with low irritation
  • Emollient properties from branched alcohol
  • Good skin tolerance

Known concerns

  • Potential trace EO/1,4-dioxane contamination from manufacturing
