About

A diethanolamine-derived fatty acid amide used as a foam booster and viscosity increaser, restricted in the EU due to nitrosamine formation potential.

Lauramide DEA (lauric acid diethanolamide) is listed in EU CosIng Annex III under reference III/60, which restricts the use of DEA and its fatty acid derivatives in cosmetic products. The restriction addresses the potential for N-nitrosodiethanolamine (NDELA) formation when DEA-containing ingredients react with nitrosating agents. Under this restriction, lauramide DEA must not be used in products containing nitrosating agents, must not exceed specified purity criteria, and is restricted to rinse-off products in some member states. The sensitization potential is low but residual free DEA is a concern.

Skin benefits

  • Foam boosting — enhances and stabilizes lather
  • Viscosity modification — thickens formulations
  • Skin conditioning — imparts softness

Known concerns

  • EU Annex III restricted (III/60) — nitrosamine formation risk (NDELA)
  • Must not be used with nitrosating agents
  • Residual free DEA may cause skin irritation
  • Sensitization concern in susceptible individuals
