Used primarily as a surfactant and emulsifying agent in industrial and laboratory applications. It helps stabilize mixtures of oil and water, making it useful in formulations for coatings, adhesives, and cleaning products. Its surface-active properties enhance wetting and dispersion, improving the performance of agrochemicals, paints, and personal care products. Also employed as a phase-transfer catalyst in organic synthesis, facilitating reactions between compounds in different phases. Its effectiveness at low concentrations and stability under various conditions make it suitable for specialized chemical processes.
