A nonionic water-dispersible surfactant for lipid-based formulations to solubilize and increase oral bioavailability of poorly water-soluble APIs. Self-emulsifies in aqueous media forming a coarse dispersion, i.e., emulsion (SEDDS). Co-emulsifier in topical formulations to improve stability of emulsions.
