The invention relates to a method for preparing ethyl lauroyl arginate hydrochloride. The method comprises the steps of dissolving L-ethyl arginate hydrochloride, lauric acid, a carbodiimide condensing agent and a catalyst in short-chain alcohol, carrying out a reaction for 4 to 48 hours at the temperature of 20 DEG C to 60 DEG C, subjecting a solution to depressurization to remove a solvent so asto obtain white solids, dissolving the white solids with water, carrying out suction filtration so as to obtain filtrate, subjecting the obtained filtrate to salting-out with an inorganic salt so asto prepare a white lumpy solid crude product, leaching the crude product with cold water for three times, and then, carrying out drying, thereby obtaining the ethyl lauroyl arginate hydrochloride. Themethod has the advantages that the method is pollution-free, the cost is low, the toxicity is low, and the purity of the product can reach 95% or more.
