Ingredient glossary / Preservative
Radish root ferment
On the label: Leuconostoc/Radish Root Ferment Filtrate · Preservative
What it is
A ferment sold as a natural preservative; weak on its own, usually one of several.
Preservatives: Preservatives stop bacteria and mould growing in a product that contains water; every water-based product needs one.
In the research
2 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- Safety Assessment of Radish Root - Derived Ingredients as Used in Cosmetics · International journal of toxicology, 2026
- Identification of didecyldimethylammonium salts and salicylic acid as antimicrobial compounds in commercial fermented radish kimchi · Journal of agricultural and food chemistry, 2015
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on cells or mice says little about a cream on a face.
Products whose label lists it
