Description

Dl-Beta,γ-Dipalmitoyl-α-Phosphatidic Acid Disodium Salt is a high-purity, synthetic phospholipid derivative, specifically a disodium salt of phosphatidic acid with defined palmitoyl chains. This compound serves as a critical intermediate and functional excipient in advanced formulation chemistry, offering excellent emulsifying and membrane-mimicking properties. It is primarily utilized by pharmaceutical, cosmetic, and life science research sectors for developing liposomal drug delivery systems, stabilizing nanoemulsions, and studying lipid bilayer dynamics.

Application

• Liposomal Drug Delivery: A key phospholipid component for constructing stable, uniform liposomes to encapsulate and deliver active pharmaceutical ingredients (APIs).
• Biomimetic Membrane Research: Used in model membrane systems (e.g., vesicles, supported lipid bilayers) to study cell membrane properties, protein-lipid interactions, and signaling pathways.
• Cosmetic & Dermal Formulations: Acts as a high-performance emulsifier and skin-conditioning agent in premium creams, serums, and other topical products.
• Diagnostic Reagent Preparation: Employed in the formulation of reagents for clinical diagnostics and biochemical assays requiring controlled lipid environments.
• Biochemical & Cell Culture Supplements: Serves as a lipid source or membrane fluidity modulator in specialized cell culture media and biochemical experiments.
• Nanoemulsion Stabilizer: Provides stability and controls the particle size distribution in oil-in-water or water-in-oil nanoemulsions for various industrial applications.
