Ethyl lauroyl arginate (LAE) is a food preservative, antimicrobial compound, and drug more commonly known as E243.[1][2][3][4] It is used to treat dermatological disorders[2] and is often provided in the form of its hydrochloride salt. LAE is an amino acid-based surfactant with broad-spectrum antimicrobial activity, high biodegradability and low toxicity. Due to these features, LAE is a preservative used in food and cosmetic formulations.
