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.

Polylysine (also known as epsilon-polylysine or ε-PL) is a naturally occurring antimicrobial polypeptide produced by fermentation of the bacterium Streptomyces albulus. It consists of a chain of L-lysine amino acids linked by epsilon-amino bonds, giving it a cationic charge that disrupts microbial cell membranes. In cosmetics it is used primarily as a natural preservative and as an anti-acne agent that helps rebalance the skin's microbiome.
