Used extensively in the formulation of liposomes and lipid nanoparticles for drug delivery systems, enhancing the stability and bioavailability of therapeutic agents. It serves as a key component in the development of mRNA vaccines, where it helps encapsulate and protect mRNA molecules, facilitating their efficient delivery into cells. Additionally, it is employed in the creation of stealth liposomes, which evade the immune system and prolong circulation time in the bloodstream. This chemical is also utilized in cosmetic formulations to improve the texture and absorption of active ingredients. Its amphiphilic nature makes it suitable for solubilizing poorly water-soluble compounds in pharmaceutical and cosmetic applications.
