US Notes
No specific FDA cosmetic ingredient restriction on DEA-Isostearate; however, FDA has expressed concern about DEA-containing ingredients and nitrosamine formation. CIR evaluated diethanolamides as a group and concluded amides safe as used when formulated to be non-irritating and when free DEA is tightly limited.
