LAE® is effective against bacteria, yeast, and molds


LAE® (Ethyl lauroyl arginate HCl) is effective as a preservative in a wide range of food and cosmetic products. It is able to disrupt the integrity of the cell membrane of these microorganisms (J. Appl. Microbiol., 2004, 96 (5) 903-912).

Efficacy shown throughout MIC values (Minimum Inhibitory Concentration) is high. For instance:

• against Gram-positive and Gram-negative bacteria MIC values are between 8 and 64 μg/ml as an average

• and against yeast and mold are between 16 and 128 μg/ml


Please consult the tables that show the MIC values of LAE® against different types of microorganisms, also pathogens, which gives an insight into LAE® ‘s wide range of activity and great effectiveness.


You can also have a look into this success case of LAE® ‘s activity against Listeria monocytogenes, and learn how it has been proved that LAE® is active against this bacteria in several tests as well as in its application in continuous production processes.
