Since we are a sister company to Active Micro Technologies
Leucidal® Liquid
is ALWAYS in Stock

Leucidal® Liquid is a natural preservative from our sister company, Active Micro Technologies.

Leucidal® Liquid is derived from radishes fermented with Leuconostoc kimchii, a lactic acid bacteria that has traditionally been used to make kimchi, this product consists of an isolated peptide that is secreted from the bacteria during the fermentation process that has been shown to have antimicrobial benefits.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).

Not working for me July 29, 2014
Reviewer: Jamie Jackson from Falcon, MO United States  
I've been testing this product since around January.  It just doesn't work for me.  It's stored at the proper temps, added at the proper temp and I've used between 2-4% gradually increasing each batch.  

When I used my home made preservative of monarda oils and evaporated extracts, I have test creams that still haven't molded after years.  After 2 months the leucidal creams are molding.  Going back to monarda and adding cottonwood bud oil as well.  I've given this an honest try and have systematically tested making small batches for the last 7 months.  Won't be buying this again, but I do appreciate your shop.

Love it! June 4, 2012
Reviewer: Doris from Boston, MA  
I love Leucidal and Love that you don't require the min orders.
The other place I obtained my leucidal from I had to spend at least 30.00
I don't know how places operate that way but I do love that if I need a small size i can obtain one.
I just placed an order for the sf version and will provide feedback.

Maggie, Thank you for all your help!
