Polyoxyl 40 stearate (PEG 40 stearate) functions as a nonionic surfactant, synthesized through the esterification of stearic acid with polyethylene glycol containing approximately 40 ethoxy units. It exhibits key biological activity in the formulation of pharmaceutical preparations and nanodrug carriers, facilitating emulsification and stabilization of active compounds. Applications include its use as a matrix component in solid lipid nanoparticles for the controlled release of encapsulated antifungal drugs, as well as serving as a base material for vaginal drug delivery systems, where it can be modified with acryloyl chloride to introduce polymerizable groups.
