Ethyl lauroyl arginate hydrochloride

Ethyl lauroyl arginate hydrochloride (CAS 60372-77-2) is a cationic amino acid-derived surfactant commercially available under trade names including Mirenat-N, Mirenat CF, CytoGuard LA, and Aminat G. It carries no E-number designation and is commonly abbreviated as LAE in technical literature.

In food preservation, LAE disrupts microbial cell membranes through electrostatic binding, providing bactericidal and fungicidal activity against pathogens such as Listeria and Salmonella at low use concentrations. In personal care formulations, it functions as both a conditioning emulsifier and preservative booster, particularly in rinse-off products where its cationic character promotes substantivity to hair and skin.

Supplied as a solid, it is available in food-contact and cosmetic grades compliant with REACH registration requirements. Procurement teams should verify conformance with applicable regional food additive regulations, as approval status differs between jurisdictions. Standard commercial packaging formats vary by supplier volume tier.
