Leuconostoc/Radish Root Ferment Filtrate: What is it?

Derived from radish roots, Leuconostoc/radish root ferment filtrate is a completely natural preservative obtained through the fermentation of radishes. This ingredient typically appears as a clear or pale yellow liquid and is known for its conditioning properties. The radish is a root vegetable that belongs to the Brassicaceae family. Once harvested, radish roots are fermented by the microorganism Leuconostoc Kimchii, a lactic acid bacteria traditionally used in the production of kimchi. During the fermentation process, the bacteria secretes a peptide that combats microbes and is beneficial for acne-prone skin.

The Leuconostoc/radish root ferment filtrate has the advantage of being water-soluble and compatible with a wide range of skincare products. It is used in small amounts (typically 0.5%) in skincare to protect them from various harmful substances that could impair their effectiveness.

The Leuconostoc/radish root ferment filtrate is safe and possesses preservation properties based on the synergy of several plant extracts. It represents a natural choice as an alternative to synthetic preservatives.

Meeting the requirements of certifications, Leuconostoc/radish root ferment filtrate is frequently used in organic skincare. In its pure state, it is a yellowish liquid diluted at a rate of 0.4% to 4% depending on the care product.
