Leucidal® Liquid From Active Micro Technologies is based on an antimicrobial peptideoriginally 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.

As with all biological materials, some attention must be paid to the conditions under which Leucidal® Liquid is used. Based on bench-scale evaluations, as well as actual product applications, Leucidal® Liquid has been found to be effective over a wide range of typical cosmetic and personal care product manufacturing conditions. The product has been found to be heat stable up to 70°C and active under both acidic (pH 3) and basic conditions (pH 8).

Technical Data Sheet





Leucidal® Liquid From Active Micro Technologies est basé sur un peptideoriginally antimicrobien dérivé des bactéries lactiques d’acide, Leuconostoc kimchii. L. kimchii est l’une des 15 espèces de micro-organismes qui composent la culture mixte responsable de la production de l’aliment de base coréen connu sous le nom de kimchi, un type de chou fermenté. Comme beaucoup de bactéries lactiques d’acide, L. kimchii est capable de limiter la croissance d’autres micro-organismes en acidifiant son environnement, mais comme c’est courant dans la nature, il n’est pas content de se limiter à un mécanisme unique de défense. En plus d’acidifier son environnement, il produit également un nouveau peptide antimicrobien. Grâce à la technologie moderne de fermentation et de biotraitement, AMT a commercialisé ce peptide antimicrobien pour produire le liquide leucidal®.

Comme pour tous les matériaux biologiques, une certaine attention doit être accordée aux conditions dans lesquelles Leucidal® Liquid est utilisé. Sur la base d’évaluations à l’échelle du banc, ainsi que des applications de produits réelles, Leucidal® Liquid s’est avéré efficace sur un large éventail de conditions typiques de fabrication de produits cosmétiques et de soins personnels. Le produit s’est avéré stable jusqu’à 70 oC et actif dans les deux conditions acides (pH 3) et de base (pH 8).

    I like it. Please use it in your redy to use products (creams, shampoo, lotions)

  2. Jenny

    Great preservative and very competitive price. I love saffire blue. It’s great to be able to get everything in one place at a great price

  3. Rebecca

    This is a great preservative. I’ve been using it in my water based products for about 9 months now and I’ve had no problems with spoilage. And customers like the sound of it 🙂

  4. Mary

    One of the natural preservatives I use in my products, and I’ve never been disappointed! I really like how it’s one of the few broad-spectrum natural preservatives out there, especially for those looking to make all-natural skin care products. It’s conveniently found at Saffire Blue for a reasonable price. I hope you never discontinue it!

  5. Carol

    this is a great product for those who want a natural preservative. I add aspen bark extract as well and have had no issues with its preserving power. In my scrubs I only use the Leucidal and have had great success. It is a bit pricey but worth it as I can honestly say my products are totally natural even at the preservative level.

  6. Mary

    I use this as my main preservative for some of my handmade products. I feel safe using this one because of its broad spectrum properties – I would definitely recommend it. It doesn’t have an odor or color so there’s no worry about it leaving a smell or adding color to products. A little on the pricey side, but Saffire Blue is one of the few places that I can find it. Please don’t discontinue this item!

  7. Stephanie
