Lauramine Oxide

  • Amphoteric surfactants
  • CAS 1643-20-5
  • IUPAC: N,N-Dimethyldodecan-1-amine oxide

May cause eye and skin irritation at concentrate strength. At typical consumer product concentrations (under 1%), irritation potential is minimal. No sensitization, no mutagenicity, no carcinogenicity. NFPA Health rating 1 (slight hazard).

Lauramine oxide (also known as lauryldimethylamine oxide or LDAO) is an amphoteric surfactant used as a foam booster, viscosity builder, and co-surfactant in cleaning formulations. It functions synergistically with anionic surfactants like SLS to enhance foam density and cleaning performance. EPA Safer Choice listed. Readily biodegradable. At typical consumer product concentrations (under 1%), the health and environmental profile is benign. Not on Prop 65, not an asthmagen, not a sensitizer. May cause mild eye and skin irritation at higher concentrations.
