Now on the Whole Foods Acceptable Premium Preservative List
- Approved for use as an ingredient in ECOCert Certified Organic products
Leucidal® Liquid SF MAX is a salicylic acid-free, probiotic-based ingredient created by the fermentation of Lactobacillus in a defined growth medium. Optimizing the fermentation process to tighten the specification for bacteriocins, Leucidal® SF MAX provides broad spectrum antimicrobial results with an increased degree of confidence. Lactobacillus is one of the species of microorganisms used to produce fermented products such as sauerkraut and kimchi, 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, 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.
During the manufacturing process, lysozyme is added to the ferment filtrate to facilitate a controlled cell lysis. This steps helps ensure the release of the antimicrobial peptides for maximized activity.
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 (please see the Technical Data Sheet for more information).

AMT Formulation Guide for AMT Preservatives
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.
- Add it to products with a pH between 3 and 8
- Performance is best at a pH below 6
- Add it during the cooling phase of the formulation process at temperatures lower than 70°C (158°F)
- We recommend adding it at cool-down when your formulation temperature is below 40°C (104°F) to avoid destabilization issues.
