Used as a corrosion inhibitor in metalworking fluids and industrial cooling systems due to its ability to form protective films on metal surfaces. Also serves as a biodegradable surfactant in personal care products, providing mild cleansing and foaming properties. Acts as an intermediate in the synthesis of amphoteric surfactants, enhancing compatibility in formulations with other ionic ingredients. Its fatty acid chain contributes to lubricity and surface activity in textile and leather processing aids.
