Leucidal® Liquid is a natural preservative from Active Micro Technologies combining the current trends for alternative preservative systems and peptide technology. Derived from radishes fermented with Leuconostoc kimchii, a lactic acid bacteria that has traditionally been used to make kimchi, this product consists of an isolated peptide that is secreted from the bacteria during the fermentation process that has been shown to have antimicrobial benefits. Leucidal® Liquid is accepted by ECOcert as an ingredient in certified organic cosmetics.  It is also on Whole Foods Acceptable Premium Preservative List.

For many cosmetic formulations Leucidal® Liquid can function as a natural alternative to synthetic preservatives. It may also be useful as a topical antimicrobial when addressing problem skin or scalp conditions. While it has only a slight odor, it will impart some color to clear cosmetic products, although it is still possible to formulate "white" emulsions.
