Leuconostoc/Radish Root Ferment Filtrate

INCI: Leuconostoc/Radish Root Ferment Filtrate

Leuconostoc/Radish Root Ferment Filtrate is a natural antimicrobial preservative produced by fermenting radish (Raphanus sativus) roots with Leuconostoc kimchii, a lactic acid bacterium traditionally used in Korean kimchi production. During fermentation, the bacteria secrete peptides with significant antimicrobial properties, making this filtrate one of the more promising natural preservative alternatives to synthetic options like parabens or phenoxyethanol.
