LAE® inhibits a wide variety of microbial species at low active levels. Minimum Inhibitory Concentration (MIC) values for LAE ® are lower compared to other common preservatives. MIC values are an indicator of intrinsic antimicrobial activity and should not be taken as recommended use concentrations in personal care products.
