Widely used in cleaning products due to its strong surfactant properties, this chemical effectively lowers surface tension, allowing for better penetration and removal of dirt and grease. It is a key ingredient in laundry detergents, dishwashing liquids, and industrial cleaners. Its anionic nature provides good foaming and emulsifying capabilities, making it effective in hard water conditions. Commonly found in household and commercial formulations where reliable cleaning performance is required. Also used in laboratories as a reference standard for testing detergent levels in water and environmental samples.
