Leucidal® SF MAX is the latest iteration of Leucidal® line. Optimizing the fermentation process to tighten the specification for bacteriocins, Leucidal® SF MAX provides broad-spectrum antimicrobial results with an increased degree of confidence.
Consumer choice is the most critical factor when it comes to cosmetic sales. Today, a growing number of consumers are opting to move away from synthetic preservatives such as parabens, formaldehyde donors, and phenoxyethanol. In addition to public pressure, the use of these synthetic materials in cosmetics is also becoming more strictly regulated. For these reasons, formulators have been actively searching for alternatives to synthetic preservatives that can provide broad-spectrum antimicrobial activity and can be added to a wide range of cosmetic applications.
A complete line of products was 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 can restrict 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 their 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 controlled cell lysis to ensure the release of the antimicrobial peptides for maximized activity.
