Description
The principal phospholipid component of lecithin and a key structural lipid in cell membranes. Used in pharmaceutical, nutraceutical, and cosmetic applications as a bioavailable choline source and as a delivery vehicle for fat-soluble actives.
Yellow to brown waxy paste or free-flowing granular powder (deoiled form). Multiple commercial grades differing in PC concentration: 35 percent (the dominant lecithin-derived format), 70 to 80 percent (enriched), and 95 percent or higher (high-purity for pharmaceutical use).
We supply food-grade and pharmaceutical-grade Phosphatidylcholine from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production. Non-GMO sunflower-derived PC is available as alternative to soybean source.
Common market grades include Soy Phosphatidylcholine 35 percent (the cost-effective workhorse), Soy PC 70 to 80 percent (enriched), Sunflower PC 35 percent (non-GMO alternative), and Pharmaceutical Grade PC 95 percent or higher (for liposomal drug delivery and clinical applications).
Bulk and reduced-MOQ shipments. Batch-level COA covering PC content, related phospholipids, acid value, peroxide value, heavy metals, and microbiology.
Introduction
Phosphatidylcholine is the principal phospholipid component of lecithin, accounting for approximately 25 to 35 percent of total phospholipids in soy lecithin and varying amounts in egg and sunflower lecithins.
Industrial production proceeds by enrichment of crude lecithin through alcohol extraction, chromatographic purification, or supercritical CO2 extraction, yielding products at progressively higher PC concentration.
Recognized as a permitted food ingredient by the U.S. FDA, the European Food Safety Authority, and equivalent regulators worldwide. Listed in major pharmacopoeias for pharmaceutical applications.
The molecule serves as both a structural lipid in cell membranes and the major dietary precursor for choline in human nutrition. High-PC supplements deliver choline in a phospholipid form that some research suggests is better absorbed than choline chloride or other simple choline salts.
Strategic positioning combines pharmaceutical liposomal drug delivery (the highest unit value), cognitive-health supplements (the fastest-growing supplement segment), cosmetic skincare applications, and food emulsifier applications across the spectrum.
Where it is used
- Liposomal drug delivery: pharmaceutical and supplement encapsulation systems
- Dietary supplements: liver-support, brain-health, and cognitive-function formulations
- Cosmetic and skincare: anti-aging serums, moisturizers, and lipid-based delivery systems
- Pharmaceutical injectable lipid emulsions and parenteral nutrition
- Functional foods positioned for brain and cognitive health
- Sports nutrition: pre-workout and recovery formulations
- Veterinary pharmaceutical applications
- Industrial applications: emulsifier in specialty food and chemical manufacturing
