About

Octyldodeceth-5 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Octyldodeceth-5 is an ethoxylated ether of 2-octyldodecanol with an average of 5 moles of ethylene oxide per molecule. Its intermediate EO degree gives it amphiphilic character (HLB ~10), useful as a co-emulsifier in both W/O and O/W systems. The branched 2-octyldodecyl group provides good emolliency. EU Cosmetics Regulation permits its use without restriction. As a mid-low EO ether, it has somewhat greater surfactant activity and skin interaction than higher-EO variants, warranting caution in leave-on formulations for sensitive skin.

Skin benefits

  • Co-emulsifier for stable formulations
  • Emollient properties from branched alcohol
  • Good for rich, protective textures

Known concerns

  • Greater skin interaction than high-EO variants
  • Potential trace EO/1,4-dioxane contamination
