Phosphatidylcholine (PC) is a class of phospholipids that incorporate choline as a headgroup. It is a major component of biological membranes and can be easily isolated from a variety of readily available sources, such as egg yolk or soybeans, from which it is mechanically or chemically extracted using solvents like hexane. It is also a member of the lecithin group of yellow-brownish fatty substances occurring in animal and plant tissues.
For industrial applications, particularly within the nutraceutical, cosmetic, and pharmaceutical sectors, Phosphatidylcholine acts as a critical precursor to acetylcholine—a neurotransmitter vital for cognitive function, memory consolidation, and synaptic plasticity. PC powder also serves as a fundamental building block for the synthesis of liposomes, which are lipid-bilayer vesicles designed for target-specific drug delivery, drastically improving the bioavailability of hydrophobic therapeutic agents.
As a leading Chinese manufacturer, we leverage state-of-the-art chromatographic separation to fractionate high-purity Phosphatidylcholine powder (ranging from 30% to 98% purity). Our specialized processing methods remove unwanted triglycerides, pigments, and off-flavors, delivering a stable, free-flowing, and highly soluble raw material optimized for complex manufacturing processes globally.

How high-purity Phosphatidylcholine powder is transforming global healthcare, nutrition, and advanced pharmaceutical delivery systems.
Phosphatidylcholine functions as the principal component of liposomal lipid bilayers. Pharmaceutical and cosmetic companies utilize our high-purity PC powder to encapsulate active drug compounds or skin-active vitamins, enhancing skin penetration, structural stability, and slow-release pharmacology.
As a direct precursor to acetylcholine synthesis, PC is a staple in brain-health supplements. TRB is dedicated to synthesizing next-generation cognitive enhancers, coupling PC with related botanical matrices to combat age-related memory decline and optimize daily focus.
PC is vital for liver cell membrane regeneration and biliary lipid excretion. With rising global rates of non-alcoholic fatty liver disease (NAFLD), pharmaceutical manufacturers rely on our bulk PC powder to manufacture clinical-grade hepatoprotective capsules and infusions.
Our proprietary purification process ensures low heavy metals, minimal solvent residues, and highly concentrated active phospholipid content.

Crude plant lecithin typically contains a mixture of oil, triglycerides, phosphatidylinositol (PI), phosphatidylethanolamine (PE), and phosphatidylcholine (PC). To manufacture high-concentration PC powder, our factories utilize multi-stage solvent extraction followed by state-of-the-art silica gel column chromatography.
By adjusting mobile phase polarities, we isolate the PC fractions with exceptional specificity. The separated fractions are then concentrated under low-temperature vacuum evaporators to preserve the thermo-sensitive lipid structure. Lastly, the product undergoes specialized spray drying or crystallization, resulting in a stable, non-hygroscopic, and free-flowing powder.
We prioritize green solvents (ethanol-based) in our extraction lines to drastically reduce chemical footprints and guarantee residue-free ingredients.
Ensuring hassle-free imports, customs clearance, and global standard certifications for seamless integration.
Our Phosphatidylcholine powder production is certified under GMP, ISO, HACCP, Organic, FDA, Halal, and Kosher. We provide full traceability documentation, including detailed Certificates of Analysis (COA), Allergen Statements, and GMO-free declarations.
We recognize that different production setups require customized physical properties. We offer variable bulk densities, customized particle size distributions (mesh size optimization), and lipophilicity tuning to match specific emulsion requirements.
With three manufacturing bases and a dedicated international logistics team, TRB guarantees stable output year-round. We provide robust localized support across the US, Europe, and Asia, assisting with customs clearance and local regulatory compliance.
