N,N-Dimethyl-1-octadecanamine-N-oxide

On the basis of the available animal and clinical data presented in this report, the CIR Expert Panel concludes that Lauramine Oxide and Stearamine Oxide are safe as cosmetic ingredients for "rinse-off" products under present conditions of use. For use in "leave-on" products, the Expert Panel concludes that Lauramine Oxide should be limited to 3.7% and Stearamine Oxide to 5%. — Cosmetic Ingredient Review (CIR)
