Question 1

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

Accepted Answer

This ingredient is used mainly as a fermentation-derived antimicrobial preservative booster, helping limit microbial growth in water-based formulas. It can also contribute mild skin-conditioning benefits from fermentation byproducts.

Question 2

Is Leuconostoc/Radish Root Ferment Filtrate Lactobacillus clean?

Accepted Answer

From a clean-beauty perspective, it is generally well accepted because it is fermentation-derived, mild, and not a common allergen. Its main caveat is performance reliability, since formulas still need proper preservation design and challenge testing.

Question 3

Is Leuconostoc/Radish Root Ferment Filtrate Lactobacillus sustainable?

Accepted Answer

This material is typically made through aqueous fermentation using renewable plant-derived feedstocks, which supports a favorable sustainability profile. It is expected to be biodegradable and is not associated with environmental persistence concerns.

Question 4

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

Accepted Answer

It is generally compatible with COSMOS natural and organic formulations when produced from approved non-GMO fermentation inputs and processed without disallowed preservatives or solvents. It fits Green Chemistry principles through renewable sourcing, water-based processing, and biodegradability.

Question 5

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

Accepted Answer

The material is a filtered fermentation product containing water-soluble metabolites such as organic acids, peptides, and other low-molecular-weight compounds that can suppress microbial growth. It is commonly used in acidic to mildly acidic systems, often around pH 3 to 6, and is best treated as part of a full preservation system rather than a stand-alone guarantee.
