Used as a non-ionic surfactant in cosmetic and pharmaceutical formulations to stabilize emulsions and improve solubility of active ingredients. Commonly found in creams, lotions, and ointments for its emulsifying and wetting properties. Also employed in laboratory settings to lyse cells and solubilize membrane proteins due to its ability to disrupt lipid membranes without denaturing proteins. Suitable for use in cleaning solutions and industrial processes where mild surfactant action is required.
