If you often take time to go through the list of ingredients in your skincare product’s label, you will often come across Leuconostoc Radish Root particularly its ferment filtrate. It has been used as a preservative mainly in skincare products and formulas.
Many consider leuconostoc radish root to be a natural harmless alternative to paraben and phenoxyethanol preservatives.
Due to increasing concerns (public pressure), strict chemical regulation and sensitization on the need to develop natural preservatives, many products have been pulled from the market.
Preservatives that were once seen as favorites are no longer acceptable and this opened up a wide gap for manufacturers to start providing preservatives based on naturally occurring ingredients and compounds. Leuconostoc Radish Root is one of the popular preservatives that has swept the market and is seen as a natural harmless option.
However, recent concerns and studies have revealed various disparities with regards to this assumption, which calls for further review and analysis. Here is a brief descriptive review including the benefits, side effects and top products.
As aforementioned, Leuconostoc Radish Root is a common preservative used in many skincare products. This ingredient is based on a peptide formerly derived from the antimicrobial lactic acid bacteria L. kimchi (Leuconostoc kimchi).
It is one of the 15 species of microorganisms used by the Korean mixed culture fermented cabbage known as kimchi. The aqueous fermented extracts are suggested for skin and scalp conditioning as well as moisturizing.
However, only 2.0 – 4.0% is suggested as safe. L kimchi extracts can acidify the environment and prevent the growth of other microorganisms. They also produce a new antimicrobial peptide which is then commercialized into the renowned leuconostoc radish root.
Various studies have been conducted on the natural preservative and its impact on skin conditioning and moisturizing has been great thus far. It is still found in many cosmetic products provided for skin and hair conditioning.
The benefits of using leuconostoc radish root as a preservative in cosmetic products are quite obvious and straightforward. The ingredient is a moisturizer and conditioner by itself. This makes it easy to use with skincare products as it does not only serve as a preservative, but also contributes to skin and hair improvement.
It is also a natural preservative that is naturally derived and registers as very low (almost insignificant) on the environmental hazard rating. However, these are not the only benefits of leuconostoc radish root. The preservative is water soluble, odorless and heat stable up to 60 degrees Celsius.
It is known to have a wide spectrum of antimicrobial application and blends perfectly with other cosmetic ingredients. It is quite mild and has very low to no potential for irritation.
Leuconostoc radish root may have been consumed in fermented cabbages in Korea where kimchi is a staple, but was only recently revealed to contain genuine skin benefits. When compared with other preservatives, it is safer and more effective with a shelf life of up to 12 months without going bad or unstable.
Although leuconostoc radish root seems to have many benefits and advantages over other preservatives, it does not lack its own drawbacks. In fact, an insight from recent research has revealed that leuconostoc radish root ferment filtrate is just as potentially hazardous as paraben and phenoxyethanol preservatives.
This came following a study to determine how the ingredient prevents bacterial growth where researchers found out that most products offered contain a lace of synthetic disinfectant known as didecyldimethylammonium chloride.
Ironically, this disinfectant does not appear naturally in radish, an indication that it is added during the manufacturing process to boost shelf life of most skincare products. Didecyldimethylammonium chloride is associated with various negative side effects and while this is not a direct result of using leuconostoc radish root, it calls for great concern since most filtrates are provided already laced with the disinfectant.
Nonetheless, more study is required to verify such findings especially since the research was done on products from the same manufacturer. Other than this unexpected finding, leuconostoc radish seems to have no negative impact on the skin or users.
It is naturally derived from an antibacterial peptide and has been part of Korean culture for a long time. It is advisable to keep it in a cool, dry place away from sunlight as it easily sediments when left still in such conditions. It is immiscible with oils.
Since it was discovered to contain various benefits for the skin and hair, leuconostoc radish root ferment extract has been pursued and manufacturers now offer different brands of the same. However, not all products you come across in the market will perform equally well or meet your requirements.
It is very crucial to review available offers before making your final choice. Fortunately, landing reliable leuconostoc radish root products is never a daunting task as they have several hallmarking attributes you can use to distinguish them from others.
From user reviews and comments, expert insights and overall product reputation, you can easily determine how a given offer performs.
This is by far the most popular leuconostoc radish root product you will come across. It is provided by AMT (active micro technologies), a company reputed for using naturally occurring compounds that contain both cosmetic and preservation properties. Leucidal Liquid is certified by ECOCERT as an organic ingredient and provided as one of the best alternatives to synthetic preservatives. It also helps to remedy scalp and skin conditions.
This is another top option in the market provided by AMT and it also features all the benefits you get from Leucidal Liquid. The only difference is that Leucidal is listed as a leuconostoc radish/root ferment filtrate while Arbocide OC is only listed as a leuconostoc ferment filtrate.
Other products that use leuconostoc radish root include Attitude Blooming Baby (cream, body wash, bubble bath…), Babytime (massage serum, lotion), Jouve Instant tightening serum and Sally B’s among others.
Leuconostoc radish root has been shown to improve skin conditioning and hair properties in both men and women. As a natural ingredient used in very small concentrations, its benefits overweigh the potential risks and it is definitely much better than other available alternatives.
There are no negative side effects and reviews from users of products that contain the ingredients and isolated research studies that link it with synthetic lacing were only done on the specific extract, not the final products.
