L-α-phosphatidylglycerol (Soy) (sodium salt) is widely used in the formulation of liposomes and lipid-based drug delivery systems due to its ability to enhance membrane stability and improve drug encapsulation efficiency. It plays a critical role in mimicking natural cell membranes, making it valuable in research related to membrane biophysics and cellular interactions. In the pharmaceutical industry, it is utilized to create biocompatible and biodegradable drug carriers for targeted therapies. Additionally, it is employed in cosmetic formulations as an emulsifier and skin-conditioning agent, helping to improve the texture and hydration of skincare products. Its applications also extend to the food industry, where it acts as a natural emulsifier in various food products.
