Here is some information from their website about Leucidal® Liquid.
INCI: Leuconostoc/Radish Root Ferment Filtrate
ECOCERT Approved/Whole Foods Acceptable
Properties: Derived from Leuconostoc kimchii, the bacterium
that has traditionally been used to make fermented Kimchi. This product
consists of a peptide that is produced by the bacterial culture during the
fermentation process which has shown to have antimicrobial benefits. This
ferment filtrate provides an effective combination of skin conditioning,
moisturizing, and antimicrobial properties.
Background: Over the past several decades there has been growing public pressure,
increasingly strict chemical regulations, preservative sensitization issues,
and the potential for developing microbial resistance to the chemical
preservative products typically used in cosmetic and personal care
formulations. These factors have resulted in numerous preservation chemicals
being pulled from the marketplace, despite being the products of choice at one
time. To offer a solution to this preservation paradigm, Active Micro Technologies (AMT) has
developed a line of products based on naturally occurring compounds that
provide active cosmetic properties, but by their very nature are also capable
of providing product preservation. This antimicrobial capability is due to
natural mechanisms developed by plants and microorganisms by which they protect
themselves from their environment and other competing organisms.
Science: Leucidal® Liquid is
based on an antimicrobial peptide originally derived from the lactic acid
bacteria, Leuconostoc kimchii. L. kimchii is one of 15 species of
microorganisms that make up the mixed culture responsible for producing the
Korean dietary staple known as kimchi, a type of fermented cabbage. Like many
lactic acid bacteria, L. kimchii is capable of restricting the growth of other
microorganisms by acidifying its environment, but as is common in nature, it is
not content to limit itself to a single mechanism of defense. In addition to
acidifying its environment, it also produces a novel antimicrobial peptide.
Using modern fermentation and bioprocessing technology, AMT has commercialized this antimicrobial peptide to produce Leucidal® Liquid.
I encourage you to visit the Active Micro Technologies website for the full Technical Data Sheet for Leucidal® Liquid . You can find it HERE.
I am very excited to start using Leucidal® Liquid in my creams and lotions. I like that this natural preservative is GMO free!! This product can provide protection from E.coli, P. aeruginosa, S. aureus, C. albicans, and A. niger.
I bought my bottle of Leucidal® Liquid from Lotioncrafter®. Stay tuned for new recipes that will include the use of this natural preservative. Please remember that if you intend to sell any oil and water emulsion products to the public that it is important to have them lab tested for microorganisms no matter which preservative you choose to use.
