Phosphatidylcholine

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

Where is Phosphatidylcholine used?

• Pharmaceutical manufacturing: liposomes and lipid nanoparticles
• Food and nutraceutical: emulsified systems including infant formula and functional beverages
• Dietary supplements: clean-label emulsification
• Biotech and cell culture: membrane lipid component in research reagents and in vitro assay systems
• Cosmetics: lamellar emulsions and liposomal delivery vehicles for topical actives
• It forms stable bilayers and liposomal structures for drug delivery and specialty nutrition systems.

Good to know: High-purity grades (90%+ PC content) are supplied for pharmaceutical and liposomal applications; lower-concentration lecithin fractions serve food and industrial uses.

Commercial specifications

• 90%+ PC content
• Liquid, gel, or powder depending on purity level and carrier format
