Moderate

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

A triethanolamine-neutralised ether sulfate used for foaming and cleansing. It works well as a surfactant but carries the typical concerns of TEA salts (nitrosamine risk) and ethoxylates (1,4-dioxane traces).

Skin benefits

  • Effective anionic surfactant and foaming agent
  • Used in shampoos and body washes
  • Good detergency at low cost

Known concerns

  • TEA salts can form nitrosamines if combined with nitrosating agents
  • Skin and eye irritation typical of ether sulfates
  • Possible 1,4-dioxane impurity from ethoxylation
  • Drying on skin at high levels
