55

Safety score · 0–100

Moderate

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

A TEA-neutralised ethoxylated alkyl sulfate surfactant for rinse-off cleansers. Effective foamer but TEA is a known nitrosamine-precursor under poor formulation, so industry is steadily phasing it out.

Function

SURFACTANT - EMULSIFYING

Skin benefits

  • Effective cleansing and foam
  • Solubilizes oils in rinse-off systems

Known concerns

  • TEA neutralizer is a secondary amine — nitrosamine-forming precursor if combined with nitrosating agents
