Description

Dl-γ-Palmitoyl-α-Lysolecithin is a synthetic, single-chain phospholipid derivative, a key intermediate in lipid biochemistry and formulation science. This compound is valued for its potent surfactant and emulsifying properties, enabling the solubilization and stabilization of challenging active ingredients. It serves as a critical functional excipient for researchers and manufacturers in the pharmaceutical, cosmetic, and advanced material sectors seeking to enhance bioavailability and product performance.

Application

• Pharmaceutical Excipient: Used as a solubilizer and permeation enhancer in lipid-based drug delivery systems (e.g., liposomes, nanoemulsions, solid lipid nanoparticles) to improve the bioavailability of poorly water-soluble APIs.
• Cosmetic Formulations: Acts as a high-performance emulsifier and skin-conditioning agent in creams, lotions, and serums, providing stable texture and enhancing skin penetration of active compounds.
• Biochemical Research: Serves as a standard or reagent in membrane biophysics studies, enzymatic assays (e.g., phospholipase substrates), and model membrane systems to investigate lipid-protein interactions.
• Nutraceutical & Food Grade Applications: Employed as an emulsifier in specialized food supplements and functional food products where precise lipid structuring is required.
• Diagnostic Reagents: Utilized in the formulation of diagnostic kits and assays that involve lipid membranes or require specific micellar environments.
• Material Science: Functions as a surface modifier or dispersing agent in the synthesis of advanced nanomaterials and biocompatible coatings.

Quality Control

Our Dl-γ-Palmitoyl-α-Lysolecithin is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and tests for residual solvents and heavy metals, ensuring it meets the stringent requirements for research and cGMP-grade applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive) and easily oxidized; allow the sealed container to reach room temperature before opening to prevent condensation. For short-term use, store desiccated at 2-8°C.
