Widely used in cleaning products due to its strong surfactant properties. It effectively lowers surface tension, allowing for better penetration and removal of dirt and grease. Commonly found in laundry detergents, dishwashing liquids, and industrial cleaners. Also used in laboratories as a reference standard for testing anionic surfactants in environmental and product samples. Its consistent composition makes it reliable for calibration in analytical methods like titration and chromatography.
