Used primarily as a surfactant and emulsifying agent in industrial and cosmetic formulations. Its long hydrophobic chain and amine functional group allow it to stabilize mixtures of oil and water, making it suitable in emulsion polymerization, personal care products like creams and lotions, and in the production of specialty lubricants. The amine group also enables salt formation, enhancing its utility in corrosion inhibitors and biocides. Additionally, it serves as an intermediate in the synthesis of quaternary ammonium compounds, which are widely used for their antimicrobial properties in disinfectants and fabric softeners.
