Phosphatidylcholine

Phosphatidylcholine (CAS 27098-24-4), commonly sourced as a soy or sunflower lecithin fraction, is a phospholipid used across pharmaceutical, food, and biotech manufacturing as a natural emulsifier and membrane-forming agent.

Its ability to form stable bilayers and liposomal structures makes it a critical functional ingredient in drug delivery and specialty nutrition systems. In pharmaceutical manufacturing, it is used to construct liposomes and lipid nanoparticles.

These structures are essential for encapsulating active compounds, improving bioavailability and controlled release profiles. Food and nutraceutical producers incorporate it into emulsified systems including infant formula and functional beverages.

It is also used in dietary supplements where clean-label emulsification is a formulation requirement. Biotech and cell culture applications rely on it as a membrane lipid component in research reagents and in vitro assay systems.

Cosmetic formulators also use it to build lamellar emulsions and liposomal delivery vehicles for topical actives. The material is available as a liquid, gel, or powder depending on purity level and carrier format.

High-purity grades (90%+ PC content) are supplied for pharmaceutical and liposomal applications. Lower-concentration lecithin fractions serve food and industrial uses to provide cost-effective emulsification solutions.

Suppliers offer both soy-derived and sunflower-derived material, with non-GMO and organic certifications available. These options ensure the product meets specific market requirements and regulatory standards for global distribution.
