Leuconostoc/radish root ferment filtrate is a synthesized chemical, usually appearing as a clear or pale yellow liquid, derived from the fermented roots of the radish (Raphanus sativus) and used for its conditioning properties.
Radishes are an edible root vegetable in the cabbage (Brassicaceae) family, cultivated around the world in many varieties and typically eaten raw for their crisp, earthy taste and crunch. To produce the root filtrate, harvested radish roots are fermented by the microorganism Leuconostoc (a lactic acid bacteria, also used to make sourdough bread and kimchi).
Leuconostoc/radish root ferment filtrate has natural antimicrobial activity, and can be used in personal care products in small amounts to enhance the stability and longevity of formulations. It also has moisturising properties, and can be used in hair care to help nourish the scalp and hair, leaving them soft and smooth.
