Acts as a surfactant and emulsifier in topical products, contributing to product stability and texture. Plays a role in lipid-based drug delivery systems due to its biocompatibility and ability to integrate into cell membranes. Investigated for use in transdermal drug delivery and dermal therapies because of its influence on membrane fluidity and permeability. Also found in some research applications related to lipid signaling and inflammation pathways.
