Now on the Whole Foods Acceptable Premium Preservative List
- Approved for use as an ingredient in ECOCert Certified Organic products
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.
Use with AMTicide Coconut for added protection against yeast and mold!
The choice of preservatives for personal care formulations should be carefully considered. This is especially true when using natural antimicrobials and or other “mild” antimicrobials. We recommend that every formula undergo stability and microbial testing to ensure adequate preservation.

Testing shows that the peptide remains active under both acidic and basic conditions, but there is a loss of activity at pH of 9.
