Question 1

What does Leuconostoc/RadishRoot Ferment Filtrate do in a cosmetic formula?

Accepted Answer

A naturally derived antimicrobial preservative and preservative booster, used to help limit bacterial growth in water-containing formulas. It is often paired with other preservation tools when broader yeast and mold coverage is needed.

Question 2

Is Leuconostoc/RadishRoot Ferment Filtrate clean?

Accepted Answer

This ingredient is generally well accepted in clean-beauty frameworks because it is fermentation-derived and usually low-irritation. The main formulation caveat is performance reliability, since preservation strength can vary by supplier grade and finished formulas still need challenge testing.

Question 3

Is Leuconostoc/RadishRoot Ferment Filtrate sustainable?

Accepted Answer

This material is made through water-based fermentation of renewable plant-derived feedstocks, which gives it a favorable sourcing profile. It is expected to be readily biodegradable and does not carry the persistence concerns associated with many fully synthetic film-formers or silicones.

Question 4

Is Leuconostoc/RadishRoot Ferment Filtrate COSMOS-approved?

Accepted Answer

It is generally permitted under COSMOS-natural and COSMOS-organic when the fermentation substrate, processing aids, and preservation system meet the standard’s requirements. It aligns well with Green Chemistry principles through renewable sourcing, fermentation-based production, and biodegradability.

Question 5

How does Leuconostoc/RadishRoot Ferment Filtrate work chemically?

Accepted Answer

The material is an aqueous fermentation it containing antimicrobial metabolites such as peptides, organic acids, and related low-molecular-weight compounds. Typical use levels are about 2 to 4 percent, with best performance in mildly acidic to neutral systems and frequent co-formulation with other preservative supports for full-spectrum protection.
