Leucidal® Liquid SF is a 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. 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.

Leucidal® Liquid SF can be used in a wide range of cosmetic products, however, to ensure optimum results, it is recommend using the following guidelines:

Incorporate the product into formulations at a pH between 3 and 7, during the cooling phase of the process at temperatures lower than 80°F. Furthermore, when working with xanthan gum or Carbopol Ultrez 10, it is best to add this product prior to the thickener.
