  • Applications

    N,N-Dimethyl-9-octadecen-1-amine-N-oxide is a long-chain tertiary amine oxide surfactant. Real-world applications include cosmetics/personal care (surfactant and emulsion stabilizer in shampoos and cleansers), household and industrial cleaners (detergency formulations), coatings and inks (wetting agent and emulsion stabilizer for paints and inks), and polymers/plastics (dispersant and processing aid in plastic and rubber formulations). It may also serve as a specialty processing aid or intermediate in certain chemical syntheses. Use is subject to local regulations and formulation limits.
