About

A castor oil-derived fatty acid diethanolamide used as a viscosity builder and emulsion stabilizer that is subject to EU Annex III restrictions due to potential nitrosamine formation.

Ricinoleamide DEA (diethanolamine ricinoleate) is the diethanolamine salt of ricinoleic acid derived from castor oil. It functions as a viscosity-controlling agent and emulsion stabilizer in cosmetic formulations. The ingredient is listed under EU Regulation (EC) No 1223/2009 Annex III (restricted substances) under reference III/60, with restrictions applying to its use due to the potential for DEA (diethanolamine) to form nitrosamines during storage or use. While the base compound is of low concern, the nitrosamine formation potential under certain conditions drives the restriction.

Skin benefits

  • Viscosity-controlling agent that improves product texture
  • Emulsion stabilizer in cosmetic formulations

Known concerns

  • Listed in EU Annex III restricted substances (ref III/60)
  • Potential for nitrosamine formation from residual diethanolamine
  • May be restricted in leave-on products above certain concentrations
