This is a liquid extract made by fermenting daikon radish with Leuconostoc bacteria. It functions primarily as a natural preservative in skincare products, helping prevent bacterial and microbial growth to extend shelf life.
Benefits
Natural preservative that helps prevent bacterial contamination
May have mild antimicrobial properties on skin
Derived from fermented ingredients, appealing to 'clean beauty' preferences
Potential concerns
Salicylic acid content may cause irritation or dryness in sensitive skin
Potential allergic reactions in individuals sensitive to radish or fermentation byproducts
Limited safety data at typical cosmetic concentrations
Science: Research shows this ingredient's antimicrobial activity comes from salicylic acid (active against Gram-negative bacteria) and didecyldimethylammonium salts (active against Gram-positive bacteria), rather than from fermentation-produced compounds as traditionally claimed. However, peer-reviewed data on its safety and efficacy specifically in skincare formulations at cosmetic use levels is limited.
