1,2-Dilauroyl-sn-glycero-3-phosphocholine is widely used in the formulation of liposomes and other lipid-based drug delivery systems. Its amphiphilic nature allows it to form stable bilayers, making it ideal for encapsulating drugs and enhancing their bioavailability. In cosmetic products, it serves as an emulsifier and moisturizer, improving skin hydration and texture. Additionally, it is utilized in research as a model membrane lipid to study cell membrane behavior and interactions. Its biocompatibility also makes it suitable for applications in biotechnology and medical diagnostics.
