Description

1-Palmitoyl-2-Arachidoyllecithin is a high-purity, synthetic phospholipid with a defined fatty acid composition. This precise molecular structure makes it a critical component for advanced research and formulation development where batch-to-batch consistency is paramount. It is primarily sought after by the pharmaceutical, nutraceutical, and advanced cosmetic industries for creating sophisticated delivery systems and model membranes.

Application

• Liposome & Nanoparticle Formulation: A key structural lipid for creating stable, uniform liposomes and lipid nanoparticles (LNPs) for drug and gene delivery.
• Biomimetic Membrane Research: Used to construct defined lipid bilayers and vesicles for studying membrane protein interactions, permeability, and cell signaling.
• Pharmaceutical Excipient: Serves as an emulsifier, solubilizer, and bioavailability enhancer in injectable and oral dosage forms.
• Advanced Cosmetic Actives: Incorporated into high-performance skincare formulations for its emulsifying properties and potential to improve skin barrier function.
• Diagnostic Reagent Manufacturing: Used in the production of reagents for clinical diagnostics and analytical kits requiring specific lipid environments.
• Cell Culture & Cryopreservation: Acts as a supplement in specialized cell culture media and as a protective agent in cryopreservation solutions.
