Our Leuconostoc Ferment Extract is a standardized fermented extract that is derived from naturally occurring compounds. It offers impressive antimicrobial activity without the risks associated with using synthetic preservatives. It is well suited for use in the formulation of the finest beauty, cosmetic and personal care products.

Leuconostoc Ferment Extract is produced by fermenting Leuconostoc kimchii in a defined growth medium. Leuconostoc kimchii, a lactic acid bacteria, is best known for its role in the creation of the delicious, spicy Korean fermented cabbage dish known as kimchi.

The extract is comprised solely of Leuconostoc Ferment Filtrate and Water. The extract is standardized to achieve a composition of 18-22% Salicylic Acid.

Our Leuconostoc Ferment Extract is suitable for use in certified organic products because the raw materials used to produce the extract are NOP-compliant as specified in Title 7, Part 205.605 and 205.606 of the Code of Federal Regulations.

Our Leuconostoc Ferment Extract is an effective anti-microbial that functions as a natural alternative to synthetic preservatives within certified organic and conventional cosmetic product formulation.

Leuconostoc Ferment Extract is water soluble and can be added to water-based formulations, or it can be added during the water phase of emulsions that maintain a pH range of 3.0-8.0. It is recommended that Leuconostoc Ferment Extract be added during the cooling phase at temperatures below 140 Degrees F (60 Degrees C) and added prior to the addition of thickeners such as xanthan gum.

All formulations should be challenge tested by a qualified laboratory to ensure that each batch is properly preserved. The method of production, the specific components of the formulation, the environment in which the batch is formulated and the method of packaging all play a crucial role in the resulting shelf life of a batch. Therefore, we cannot guarantee your results when incorporating natural antimicrobials and preservatives into your formulations. Only lab challenge testing can determine how and if an antimicrobial/preservative is achieving the desired results.

“Your company is top notch!”

“I just had to write you and tell you that your company is top notch! I inadvertently used the wrong zip code when I ordered my products. however, you caught the error and delivered it to the correct location. I cannot tell you how grateful I am, because I really needed these products today. This is my first order from FNWL. Your packaging is superb. Nothing is leaking or torn and no product is wasted (which is something that I cannot say about all suppliers). I will be placing another order next week, and just wanted you to know that I appreciate a great business supplier that will take the time to ensure quality to their customers. Thank you!!!!”
