Widely used as an emulsifier in pharmaceuticals, cosmetics, and food products. Helps stabilize oil-in-water emulsions by reducing surface tension. Commonly found in creams, lotions, and ointments to improve texture and consistency. Used in vaccine formulations to prevent aggregation of antigens and enhance stability. Acts as a solubilizing agent for poorly water-soluble compounds in drug delivery systems. Employed in cell culture media to reduce foaming and prevent cell clumping. Also utilized in agricultural formulations to improve the dispersion of pesticides and herbicides on plant surfaces.
