An anionic surfactant blending triethanolamine with lauryl ether sulfate to provide rich foam in shampoos and body washes. Its TEA component triggers nitrosamine concerns when poorly formulated.

Skin benefits

  • Effective anionic surfactant producing dense foam in cleansers
  • Strong cleansing action removing oil and dirt
  • Often milder than ammonium or sodium lauryl sulfate in formulation feel

Known concerns

  • Triethanolamine salt can form nitrosamines if combined with nitrosating agents
  • Lauryl sulfate surfactants can be drying and irritating with prolonged exposure
  • TEA-based ingredients face EU restrictions to limit nitrosamine risk
  • Ethoxylated surfactants may contain trace 1,4-dioxane impurities
