Widely used in cleaning products due to its strong surfactant properties. It effectively lowers surface tension, allowing for better wetting and removal of dirt and grease. Commonly found in laundry detergents, dishwashing liquids, and industrial cleaners. Its anionic nature provides good foaming and emulsifying action, making it ideal for formulations requiring high cleaning efficiency. Also used in laboratories as a reference standard for testing detergent levels in water and environmental samples. Stable and effective in hard water, which enhances its performance in household and commercial applications.
