Characteristics and application of natural egg yolk lecithin PL-100M

Egg yolk lecithin PL-100M is a pharmaceutical injection grade phospholipid (CAS No. 93695-90-6). The normal product is a light yellow powder with uniform color or slight lumps. It has excellent solubility in chloroform, and also has good solubility in ether, n-hexane and ethanol. It has certain dispersibility in water and can be dissolved in soybean oil at 60°C under high shear, so it is convenient to use.

Basic information of PL-100M is as follows:   

1 Product name: Egg Yolk lecithin

2 English name: PL-100M

3 Chemical name: egg yolk lecithin

5 Manufacturer: Made in Japan

6 CAS Number: 93685-90-6

7 DMF number: 15449

8 Record registration number: F20190001254

9 Uses: liposomes, emulsifiers

10 Purity: Contains phosphatidylcholine﹥68%, Contains phosphatidylethanolamine﹤20% (see COA for details)

11 Solubility: Easily soluble in chloroform, soluble in ether or n-hexane, soluble in ethanol, almost insoluble in water or acetone

12 molecular weight: the mixture has no fixed molecular weight

The product quality standard is in accordance with the import registration standard. Like other egg yolk lecithins, it needs to be stored at -20°C in an airtight manner. The validity period is three years. If stored improperly or exposed to air for a long time, the color will turn from light yellow to red and then brown, which will increase the smell and reduce the quality of the product.

The application of PL-100M

PL-100M is mainly used as an emulsifier for fat emulsions for injection, including nutritional and therapeutic fat emulsions. It has excellent emulsifying properties and product stability. The product is soluble in soybean oil at 60°C, which is convenient for operation; it keeps the emulsion at a relatively stable particle size and PH value, prolongs the validity period of the emulsion, reduces the use of egg yolk lecithin, and reduces production costs.
