Leuconostoc/Radish Root Ferment Lysate Filtrate

TL;DR. This ingredient functions mainly as a naturally derived antimicrobial preservative or preservative booster, helping control bacteria and some yeast or mold growth in water-based formulas. It is often used when a brand wants a fermentation-based preservation system rather than a conventional synthetic preservative.

What does Leuconostoc/Radish Root Ferment Lysate Filtrate do in a cosmetic formula?

This ingredient functions mainly as a naturally derived antimicrobial preservative or preservative booster, helping control bacteria and some yeast or mold growth in water-based formulas. It is often used when a brand wants a fermentation-based preservation system rather than a conventional synthetic preservative.

Is Leuconostoc/Radish Root Ferment Lysate Filtrate clean?

From a clean-beauty perspective, it is generally well regarded because it is fermentation-derived, low-odor, and usually well tolerated on skin. The main caveat is performance, since it may need support from other preservative hurdles and should be validated with microbial challenge testing.

Is Leuconostoc/Radish Root Ferment Lysate Filtrate sustainable?

This material is made through fermentation of renewable plant feedstock in water-based processing, which gives it a favorable sourcing profile. It is expected to be biodegradable and does not carry major persistence or bioaccumulation concerns.

Is Leuconostoc/Radish Root Ferment Lysate Filtrate COSMOS-approved?

It is generally compatible with COSMOS-natural and COSMOS-organic formulations when produced from approved natural feedstocks and compliant processing aids. It aligns well with Green Chemistry principles through fermentation, renewable inputs, and water-based manufacture.

How does Leuconostoc/Radish Root Ferment Lysate Filtrate work chemically?

The molecule profile is not a single defined compound, but an aqueous it containing antimicrobial peptides, organic acids, and other soluble fermentation metabolites. Typical use levels are about 2% to 4%, with best performance in mildly acidic to neutral systems, and it is commonly paired with chelators, glycols, pH control, or other preservation supports.
