About

Octyldodeceth-2 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Octyldodeceth-2 is an ethoxylated ether of 2-octyldodecanol with an average of only 2 moles of ethylene oxide per molecule, giving it a low HLB of approximately 4-5. It is primarily used as a lipophilic co-emulsifier in W/O systems. The short EO chain means the molecule has greater surfactant activity and skin interaction potential compared to higher-EO variants. EU cosmetics regulation permits its use without restriction, but the low ethoxylation degree warrants caution in leave-on products for sensitive skin.

Skin benefits

  • Lipophilic co-emulsifier for W/O formulations
  • Improves skin barrier feel

Known concerns

  • Greater skin interaction from low EO degree
  • Moderate skin/eye irritation potential
