Leucidal® SF MAX is the latest iteration of Leucidal® line. Optimizing the fermentation process to tighten the specification for bacteriocinsLeucidal® SF MAX provides broad spectrum antimicrobial results with an increased degree of confidence.

A full line of products were developed and derived from naturally occurring compounds that provide broad spectrum antimicrobial protection. As a result, these novel natural antimicrobials are considered self-preserving cosmetic actives and therefore can be used as consumer-friendly alternatives to synthetic preservatives in a wide range of cosmetic applications.

Leucidal® SF MAX is a powerful 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. 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.
