About

A myristic acid diethanolamide foam modifier used in surfactant systems, subject to EU Annex III restriction (III/60) due to DEA-related nitrosamine concerns.

Myristamide DEA is the diethanolamide of myristic acid (tetradecanoic acid), used as a foam booster and viscosity modifier in cleansing formulations. Like all DEA fatty acid amides, it falls under EU CosIng Annex III reference III/60, which restricts DEA derivatives due to the risk of NDELA formation. Compliance requires that the ingredient be free of secondary amines as impurities, formulations must not contain nitrosating agents, and it should be used in accordance with purity specifications. Similar restrictions apply in the US under CIR recommendations.

Skin benefits

  • Foam boosting and stabilization
  • Viscosity control in liquid formulations

Known concerns

  • EU Annex III restricted (III/60) — NDELA nitrosamine formation risk
  • Must not be combined with nitrosating agents
  • Residual free DEA is a sensitization concern
  • Purity requirements must be met
