Used extensively in the formulation of liposomes and lipid-based drug delivery systems due to its ability to stabilize membranes and enhance drug encapsulation efficiency. It is a key component in creating biocompatible and biodegradable carriers for targeted drug delivery, particularly in cancer therapy and vaccine development. Additionally, it is employed in cosmetic products as an emulsifier and moisturizer, improving skin hydration and texture. In research, it serves as a model phospholipid for studying membrane dynamics and interactions in cellular systems. Its amphiphilic nature makes it valuable in creating nanostructured materials for various biomedical applications.
