  • Applications

    Octadecanamide, N-(3-(dimethyloxidoamino)propyl)-, CAS 372973-82-5, is a long-chain amide bearing a functional side group that is commonly regarded as a cationic surfactant precursor or a processing additive for polymers. In cosmetics and personal care, it may function as a surfactant to stabilize emulsions and contribute to a conditioning or softening feel on skin and hair. In coatings and inks, it can serve as a surfactant, adhesion promoter, or dispersant to improve wetting, adhesion, and pigment dispersion. As a long-chain amphiphile, it may act as a lubricant or slip additive in plastics and rubber formulations, helping processing and end-use properties. It may also be used as a component in cleaning formulations or industrial emulsions, subject to formulation goals and regulatory constraints.
