Description

Lecithin CAS NO 55128-59-1 is a naturally occurring mixture of phospholipids, primarily phosphatidylcholine, phosphatidylethanolamine, and phosphatidylinositol, derived from sources like soybeans, eggs, or sunflower seeds. This versatile amphiphilic compound is essential as a multifunctional food additive, a critical pharmaceutical excipient, and a key ingredient in industrial applications. It is indispensable for industries requiring natural emulsification, stabilization, and nutritional fortification, such as food manufacturing, nutraceuticals, cosmetics, and animal feed.

Application

• Food & Beverage Industry: Primary natural emulsifier and stabilizer in chocolate, margarine, baked goods, and instant powders to prevent separation and improve texture.
• Pharmaceuticals & Nutraceuticals: Used as a dispersing agent, emulsifier, and bioavailability enhancer in lipid-based drug delivery systems and dietary supplements for brain and liver health.
• Cosmetics & Personal Care: Acts as an emollient and emulsifier in creams, lotions, and lipsticks, providing skin conditioning and stabilizing oil-in-water formulations.
• Animal Nutrition: Incorporated into feed for young livestock and poultry as an emulsifier to improve fat digestion and nutrient absorption.
• Industrial Applications: Serves as a release agent, antioxidant, and viscosity modifier in paints, coatings, and lubricants.
• Dietary Supplements: Marketed for its choline content, supporting cognitive function and cellular membrane integrity.

Quality Control

Our lecithin is produced and tested under strict quality management systems. We offer grades compliant with FCC (Food Chemicals Codex) and USP-NF (United States Pharmacopeia) standards, ensuring safety and performance for food, pharmaceutical, and nutraceutical applications. Each batch is analyzed for key parameters such as phospholipid content, acetone-insoluble matter, and peroxide value. A Certificate of Analysis (COA) is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality, especially after opening the original container. Keep away from heat and incompatible materials.
