Leucidal® Liquid SF Natural Moisturizing Antimicrobial

Leucidal Liquid SF is a probiotic-based ingredient created by the fermentation of Lactobacillus in a defined growth medium. Lactobacillus is one of the species of microorganisms used to produce fermented products, such as kimchi and sauerkraut, a Korean dietary staple, from cabbage. Like many members of the lactic acid bacteria family, Lactobacillus is capable of restricting the growth of other microorganisms by acidifying its environment. However, Lactobacillus also produces novel antimicrobial peptides, known as bacteriocins, that are capable of providing broad spectrum antimicrobial protection. During the manufacturing process, lysozyme is added to the ferment filtrate to facilitate a controlled cell lysis to ensure the release of the antimicrobial peptides for maximized activity.

Leucidal® Liquid SF works best with water-based recipes, like toners, and gels, like hyaluronic acid gel. It can be used as a secondary moisturizing preservative in lotions and creams, and in more complex formulations containing actives. For a broad-spectrum preservative in formulations containing active ingredients, use Leucidal® SF Complete. Certain formulations may require additional preservatives in combination with this ingredient to offer complete broad-spectrum protection. Your own testing is recommended to ensure adequate preservation coverage.
