About

Trideceth-11 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Trideceth-11 is a non-ionic surfactant derived from tridecyl alcohol ethoxylated with approximately 11 moles of ethylene oxide. The slightly lower EO number compared to Trideceth-15 gives it a more lipophilic character, affecting its emulsification profile and skin feel. EU cosmetic regulation (EC 1223/2009) does not list Trideceth-11 in any restriction annex; the primary safety consideration is potential 1,4-dioxane residue from manufacturing, which reputable suppliers control to ppm levels.

Skin benefits

  • Versatile emulsifier for cosmetic emulsions
  • Contributes to product stability and texture

Known concerns

  • Potential 1,4-dioxane residual from ethoxylation process
  • Moderate irritation potential in sensitive skin at high concentrations
