Description

Lecithin CAS NO 8002-43-5 is a naturally occurring mixture of phospholipids, primarily phosphatidylcholines, derived from sources such as soybeans, eggs, or sunflower seeds. This versatile amphiphilic compound is a critical functional ingredient, serving as an effective emulsifier, stabilizer, and dispersing agent across numerous industries. It is an essential raw material for manufacturers in the food and beverage, pharmaceutical, nutraceutical, and cosmetic sectors, where it improves texture, shelf life, and bioavailability.

Application

• Food & Beverage Industry: As a key emulsifier and release agent in chocolates, margarines, baked goods, and instant powders to ensure consistent texture and prevent separation.
• Pharmaceutical & Nutraceuticals: Used as an excipient in tablet and capsule formulations for its emulsifying properties and as a source of choline in dietary supplements for cognitive and liver health support.
• Cosmetics & Personal Care: Functions as an emollient and emulsifier in creams, lotions, and lipsticks, providing skin conditioning and stabilizing oil-in-water formulations.
• Animal Feed: Incorporated as a nutritional additive and pellet binder to improve fat absorption and feed consistency.
• Industrial Applications: Acts as a release agent in the manufacturing of plastics, paints, and coatings, and as a dispersing agent in ink and dye formulations.
• Dietary Emulsifier: Utilized in clinical nutrition and weight management products to stabilize fat-soluble vitamins and nutrients in liquid formulations.

Quality Control

Our Lecithin is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and compliance with major international standards, including FCC (Food Chemicals Codex) and USP-NF (United States Pharmacopeia) for applicable grades. Each lot undergoes comprehensive analysis for key parameters such as phospholipid content, acid value, peroxide value, and moisture. A detailed Certificate of Analysis (COA) documenting these results is available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air, heat, or moisture should be avoided to maintain stability and prevent degradation. For long-term storage, consider using an inert atmosphere (e.g., nitrogen).
