FAQ
A1: Egg Yolk Lecithin naturally contains a significantly higher concentration of phosphatidylcholine (typically 70% or higher after purification) and a higher proportion of saturated palmitic and stearic fatty acid chains. This structure provides better resistance to oxidation and forms more stable, less permeable liposomal membranes than highly unsaturated plant lecithins.
A3: Egg Yolk Lecithin swells in water to form lamellar liquid-crystalline phases. For optimal dispersion, pre-hydrate the lecithin in warm deionized water (45 to 55 degrees Celsius) under moderate mechanical agitation, or dissolve it in the warm oil/polyol phase prior to high-shear homogenization.
A4: Standard commercial supply is available in 1 kg and 5 kg nitrogen-flushed aluminum foil pouches inside protective fiber drums, as well as 20 kg bulk containers. Every shipment includes a lot-specific Certificate of Analysis (COA), HPLC chromatogram, GHS Safety Data Sheet, and BSE/TSE-free certificate.
