Used as a specialty surfactant and emulsifier in industrial formulations, particularly in lubricants and metalworking fluids. Its long hydrocarbon chain and amide structure provide excellent thermal stability and surface activity, making it effective in stabilizing oil-water mixtures. Also serves as an intermediate in the synthesis of functional coatings and corrosion inhibitors. Due to its low volatility and strong adsorption properties, it is employed in additives for improving boundary lubrication and reducing friction in high-temperature applications.
