Used as a surfactant and corrosion inhibitor in industrial water treatment systems. It functions effectively in metalworking fluids to reduce friction and prevent rust formation. Also serves as an intermediate in synthesizing fabric softeners and antistatic agents for textiles. Its long hydrocarbon chain provides strong surface activity, making it suitable for emulsion stabilization in coatings and agrochemical formulations. Additionally employed in oilfield chemicals to control scale and inhibit microbial growth in drilling fluids.
