Description

L-α-Lecithin is a high-purity, naturally derived phospholipid complex, also known as phosphatidylcholine. This compound is a critical functional ingredient valued for its exceptional emulsifying, dispersing, and cell membrane-supporting properties. It is essential for manufacturers in the pharmaceutical, nutraceutical, and advanced food technology sectors seeking premium-grade raw materials for sensitive formulations.

Application

• Pharmaceutical Excipients: Used as a solubilizer, emulsifier, and bioavailability enhancer in injectable, oral, and topical drug delivery systems (e.g., liposomes, mixed micelles).
• Nutraceutical & Dietary Supplements: A key active ingredient in brain health, liver support, and nootropic formulations due to its choline content and role in cell membrane integrity.
• Advanced Food Technology: Functions as a high-performance emulsifier and stabilizer in premium chocolates, infant formula, and nutritional beverages requiring superior quality and stability.
• Cosmetic & Personal Care: Employed in high-end skincare products for its moisturizing, skin barrier repair, and liposomal encapsulation properties.
• Research & Biochemicals: Serves as a critical reagent in cell culture media, membrane studies, and biochemical research applications.

Quality Control

Our L-α-Lecithin is produced and tested under a stringent quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. Certificates of Analysis (COA) detailing key parameters such as phosphatidylcholine content, peroxide value, and solvent residues are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider filling the headspace with an inert gas (e.g., nitrogen or argon) to maintain stability.
