Leucidal® Liquid SF MAXis a powerful probiotic-based ingredient created by the fermentation of Lactobacillus in a defined growth medium. Like many members of the lactic acid bacteria family, Lactobacillus is capable of restricting the growth of other microorganisms by acidifying its environment. However, in addition to acidifying its environment, Lactobacillus also produces novel antimicrobial peptides, also known as bacteriocins, that are capable of providing broad spectrum antimicrobial protection.
For many cosmetic formulations Leucidal® Liquid SF MAX can be used in a wide range of cosmetic products, however to ensure optimum results we recommend using the following guidelines. As with all biological materials some attention must be paid to the conditions under which Leucidal® Liquid SF MAX can be used. 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. The suggested use levels are typically between 2 and 4%.
The ability of Leucidal® Liquid SF MAX to inhibit the growth of a variety of bacteria and fungi was determined used the Minimum Inhibitory Concentration (MIC) test. The results indicated Leucidal® Liquid SF MAX has the ability to provide broad spectrum antimicrobial protection
M15025-Leucidal® SF Complete is a blend of 75% Leucidal® Liquid SF and 25% AMTicide® Coconut (a coconut ferment with antifungal properties).
M15019MAX-Leucidal® SF Max is Active Micro Technologies' newest product. Due to its higher content of antimicrobial peptides (bacteriocins), it is expected to be more active against competing bacteria, yeasts and moulds.
The Complete may work as a mixture in this ratio for some applications. In other applications, the mix ratio may not be optimal.
M15019MAX-Leucidal® SF Max has, in our opinion, advantages over the Complete
- broad-spectrum antimicrobial including yeasts and moulds
- odourless (in the case of Complete, coconut odours from AMTicide Coconut can permeate)
- compatible with many formulations
