Used primarily as a surfactant in various industrial and household cleaning products. It helps in reducing surface tension, enhancing the cleaning efficiency of detergents and soaps. Also employed in the formulation of personal care items like shampoos and body washes, where it aids in the removal of dirt and oil from skin and hair. In industrial settings, it serves as a wetting agent and emulsifier in processes requiring the stabilization of mixtures that would otherwise separate. Additionally, it finds application in the textile industry as a dyeing assistant, improving the uptake and fixation of dyes on fabrics. It is also used as an ion-pairing reagent in high-performance liquid chromatography (HPLC) for the separation and analysis of basic compounds, such as in pharmaceutical testing.
