You have spoken, and they listened. 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 important 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 into a wide range of cosmetic applications. 

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.

BENEFITS

A skin moisturization study was performed using an untreated control, generic cream base, and an experimental with the same cream base containing 2.0% Leucidal® SF Max. When compared to the base cream Leucidal® SF Max improved moisturization by 14.38% and after 24 hours and by 25.00% after four weeks. Based on these results, adding this innovative product provides the formulator the opportunity to capitalize on both the natural antimicrobial properties of Leucidal® SF Max, as well as its ability to provide potent moisturizing benefits to the cosmetic formulation.

Leucidal® SF Max was designed to maximize the effectiveness of the antimicrobial peptides in our original Leucidal® Liquid SF. The ability of Leucidal® SF Max to inhibit the growth of a variety of bacteria and fungi was determined using the Minimum Inhibitory Concentration (MIC) test.

Leucidal® SF Max can be used in a wide range of cosmetic products, however to ensure optimum results we recommend using the following guidelines. Incorporate the product into formulations at a pH between 3 and 8, during the cooling phase of the process at temperatures lower than 70°C.

We always recommend that every formula undergo stability and microbial testing to ensure adequate preservation.

Storage: Protected from direct light and humidity at a temperature of 50°-77°F (10°-25°C) 

Shelf life: 12 months, properly stored, in sealed container. 

This product should be added to a formulation at the recommended usage rate
