LABSA serves as a wetting agent, emulsifier for agricultural herbicides, and in emulsion polymerization. Surfactants, in general, are widely used across industries to enhance interactions between polar and non-polar substances, facilitating the mixing of oil and water or water and minerals.
LABSA is a key component in the production of laundry detergents, cleaning powders, detergent cakes, liquid soaps, oil soaps, scouring bars, and various anionic specialty products. In the textile industry, it is used as a washing and mercerizing agent. Additionally, LABSA is applied in small quantities as a wetting agent/emulsifier, in combination with other surfactants, to produce foaming toilet soaps.
