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.
Use with Propanediol 1,3 for added protection against yeast and mold.
Leucidal Liquid SF MAX is Salicylate Free. It is also GMO Free and no ethoxylation, irradiation, sulphonation, hydrogenation, or ethylene oxide is used in processing. The solvent used for extraction is simply water. There are no additional preservatives or antioxidants.
Leucidal® Liquid SF MAX is a probiotic-based ingredient created by the fermentation of Lactobacillus in a defined growth medium. Leucidal® SF MAX provides broad spectrum antimicrobial protection. Leucidal® SF Max can be used in a wide range of cosmetic products, however to ensure optimum results it is recommended that it is incorporated into formulations at a pH between 3 and 8, during the cooling phase of the process at temperatures no higher than 70°C. HOWEVER, we recommend cooling to 40°C to ensure the best stability for the final product.
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.

really glad u carry this as its hard to find!! maybe bigger sizes one day?! thanks soap n more xo
I am so happy to find a preservative so natural as the Leucidals. Leucidal SF Max works best along side Amticide. I am crafting with the most natural, raw, unrefined ingredients so use both the Leucidal SF Max and the Amticide at the highest recommended dosage of 4%. Below this, I did have stability issues, but since using the higher % (I was at first using the lower recommended useage of 2%), my emulsions have been really lovely. I am happy, so happy to find such a product and highly recommend using this as a preservative but with the Amticide.
