  • Applications

    1-Palmitoyl-2-oleoylphosphatidylcholine (CAS 6753-55-5) is a defined phospholipid commonly used as an emulsifier and lipid component in cosmetic and personal-care formulations, where it can participate in liposome formation to encapsulate actives and support moisture retention. In pharmaceutical contexts, it serves as a liposome constituent for drug delivery systems and as a model membrane component in membrane biology studies. It also functions as an intermediate for the synthesis of other phospholipids and related lipid materials, with applications in biomaterials, coatings, and formulation science. In research settings, it provides a well-defined lipid standard for model membrane experiments and related membrane-property investigations.
