Lauric arginate, also known as LAE® (Ethyl lauroyl arginate) is a synthetic derivate synthetized from L-arginine, lauric acid and ethanol. Due to its cationic and surfactant nature, it is an effective preservative against gram-positive and gram-negative bacteria, such as: Listeria monocytogenes, Leuconostoc mesenteroides, Staphylococcus aureus, Salmonella, E. coli, Campylobacter jejuni, Bacillus cereus, Clostridium botulinum, among others. It has also shown activity against moulds and yeasts.


Mirenat® is the trade name of the range of formulated products based on LAE®, intended for the food industry.


Aminat® is the trade name of the range of formulated products based on LAE®, intended for the cosmetic industry.

Cosmetics preservative based on LAE® (Lauric arginate)


LAE® is a technological innovation, a safe and active compound for preservation that is hydrolyzed in the human body by chemical and metabolic pathways breaking the molecule into natural compounds common in human diet (lauric acid, arginine, ethanol).


This feature gives LAE® a remarkable degree of safety. Its non-toxicity is demonstrated by numerous toxicological studies carried out by institutions like Huntingdon Life Sciences, CSIC, The University of Barcelona, SafePharm, ABC Research, EVIC, NOTOX, CIDASAL, among others (see the entire list here).
