Used extensively in the formulation of lipid nanoparticles for drug delivery systems, particularly in mRNA vaccines and other therapeutic applications. Enhances the stability and bioavailability of encapsulated drugs by forming a protective layer around the nanoparticles. Commonly employed in the development of targeted cancer therapies and gene delivery systems due to its ability to improve cellular uptake and reduce immunogenicity. Also utilized in cosmetics and personal care products as an emulsifier and stabilizer, providing a smooth texture and enhancing product performance.
