Leucidal® Liquid – Natural Antimicrobial Preservative
Leucidal® Liquid is a natural, broad-spectrum antimicrobial preservative derived from radishes fermented with Leuconostoc kimchii, a lactic acid bacteria traditionally used in kimchi. This fermentation process yields a peptide with potent antibacterial properties, offering an effective alternative to synthetic preservatives in cosmetic formulations. Leucidal® Liquid is Whole Foods Acceptable and ECOCert Approved for use in Certified Organic products.
For enhanced mold and yeast protection, combine with AMTicide® Coconut.
