What it is
Lactobacillus/radish root ferment filtrate is the liquid obtained when Lactobacillus bacteria ferment radish root, yielding antimicrobial peptides that help protect formulas from microbial growth. It is popular as a natural-positioned alternative to conventional preservatives and also provides mild skin conditioning. In sun-care products it is used to support formula preservation.
Safety & warnings
This ferment filtrate is generally well tolerated and is commonly chosen for natural-leaning formulas. Its preservative capacity can be more limited than conventional systems, so it is sometimes combined with other agents. Sensitivity is uncommon, and it is not a recognized fragrance allergen.
Origin & sourcing
Biotechnological and plant-derived. It is produced by fermenting radish (Raphanus sativus) root with Lactobacillus bacteria and filtering the broth.
