CAS 139-96-8
45

Safety score · 0–100

Moderate

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

A TEA-based foaming detergent. Cleanses well but the triethanolamine moiety can form nitrosamines if formulated alongside nitrosating agents, and the molecule itself is more irritating than gentler modern surfactants.

Skin benefits

  • Effective foaming and cleansing surfactant
  • Good degreasing power
  • Mild to moderate emulsion stabilisation

Known concerns

  • Nitrosamine contamination risk from TEA (triethanolamine) + nitrosating agents
  • Can defat and dry skin with prolonged contact
  • Eye and skin irritation, especially at higher concentrations
  • Strictly regulated under EU rules to avoid nitrosamine formation
