Diethanolamides are common ingredients used in cosmetics to act as a foaming agents or as emulsifiers.[1] Chemically, they are amides formed from diethanolamine and carboxylic acids, typically fatty acids.

Examples include:

  • Cocamide diethanolamine
  • Lauramide diethanolamine
  • Oleamide diethanolamine
