Ethyl Lauroyl Arginate HCl is a unique antimicrobial active ingredient with cationic surfactant properties derived from the natural occurring substances L-Arginie and lauric acid. It is used as an antimicrobial in the sanitation of preserved foods & in cosmetics as a preservative.

L-Arginine is esterified to L-Argininine ethyl ester using ethanol & dry HCL and condensed with Lauroyl chloride in the presence of Sodium hydroxide solution. The reaction mass is extracted with solvent. The extract is allowed to chilled & getting precipitate of LAE salt, which is filtered through centrifuge and dried.
