Used as a non-ionic surfactant in pharmaceutical and cosmetic formulations, this compound functions as an emulsifier and solubilizing agent. It helps stabilize oil-in-water emulsions, making it valuable in creams, lotions, and topical drug delivery systems. Due to its polyether chain, it exhibits good water solubility and mildness on the skin, suitable for sensitive products. It is also employed in cleaning formulations for its ability to reduce surface tension and enhance wetting properties.
