  • Applications

    Choline (CAS 62-49-7) is widely used as a nutritional supplement for humans and as a feed additive to support growth and metabolism in poultry and other livestock. It also serves as a key precursor for glycine betaine and phosphatidylcholine, enabling production of lipid-based ingredients, emulsifiers, and liposomal formulations for food, pharmaceutical, and cosmetic applications. Choline-derived quaternary ammonium compounds are used as intermediates to manufacture surfactants and specialty cleaners in industrial manufacturing. In pharmaceuticals and drug delivery, phosphatidylcholine-based liposomes and related choline-containing lipids are employed for encapsulation and solubilization. In cosmetics and personal care, lecithin and phosphatidylcholine from choline-containing sources act as emulsifiers and conditioning agents. Additionally, choline salts (e.g., choline chloride) are explored as components in green solvent systems such as deep eutectic solvents for cleaning, coatings, and polymer processing, subject to local regulations and formulation limits.
