MADE OF:

Leucidal® Liquid PT is a probiotic-based ingredient made through the fermentation of Lactobacillus in a controlled growth medium. Lactobacillus, a microorganism used in producing fermented products like sauerkraut and kimchi, helps restrict microbial growth by acidifying its environment. During fermentation, Lactobacillus is exposed to high pH and low oxygen levels, along with undecylenic acid from castor beans, to stimulate the production of secondary metabolites. These metabolites offer conditioning benefits and include novel antimicrobial peptides that give Lactobacillus a competitive edge in nature. After fermentation, lysozyme is added to facilitate controlled cell lysis, ensuring the release of antimicrobial peptides for enhanced efficacy.

Information provided is a guideline. Consult stability data for effects of temperature variations on product specifications.

Ensure all formulations undergo stability and microbial testing for adequate preservation.

Please note that the Leucidal® line of products are not conventional preservatives but multifunctional natural antimicrobials. While these products have been successfully used in formulations for nearly two decades, integrating a natural antimicrobial isn't as straightforward as swapping it for a synthetic preservative—formulation techniques may need to be adjusted to ensure effective preservation.
AMT’s natural antimicrobials undergo stringent challenge testing based on Personal Care Products Council (PCPC) Microbiology Guidelines, demonstrating strong performance against common bacteria, yeast, and mold. Leucidal® Liquid offers broad-spectrum antimicrobial protection, though some formulas may require an additional antifungal booster like AMTicide® Coconut. It's also important to understand that AMT ingredients are not biocidal and are not intended to eliminate pre-existing bioburdens; rather, they help safeguard final formulations from contamination. Given the potential for contamination during production, it is crucial for manufacturers to establish and follow rigorous quality control protocols.
