Leuconostoc Ferment Filtrate ●
TL;DR. This ingredient is used as a natural-origin antimicrobial support system, most often to help protect water-based formulas from bacterial growth. It is typically positioned as a preservative or preservative booster rather than a broad, stand-alone preservation system for every formula type.
What does Leuconostoc Ferment Filtrate do in a cosmetic formula?
This ingredient is used as a natural-origin antimicrobial support system, most often to help protect water-based formulas from bacterial growth. It is typically positioned as a preservative or preservative booster rather than a broad, stand-alone preservation system for every formula type.
Is Leuconostoc Ferment Filtrate clean?
From a clean-beauty perspective, it is generally well tolerated and has little restricted-list friction. The main caveat is performance, since formulas using it still need proper challenge testing, especially when yeast and mold protection is required.
Is Leuconostoc Ferment Filtrate sustainable?
This material is typically produced through low-temperature fermentation using plant-derived carbohydrate feedstocks, followed by filtration. It is expected to be readily biodegradable and has lower persistence concerns than many synthetic antimicrobial systems.
Is Leuconostoc Ferment Filtrate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic frameworks when made from permitted substrates and processed with allowed fermentation and filtration methods. It fits Green Chemistry principles through fermentation-based manufacture, aqueous processing, and biodegradable composition.
How does Leuconostoc Ferment Filtrate work chemically?
The material is a filtered aqueous fermentation product containing small antimicrobial peptides, organic acids, and other water-soluble metabolites generated by lactic-acid bacteria. It is usually formulated in the water phase, works best in mildly acidic to neutral systems, and needs compatibility testing because high heat, strong electrolytes, or challenging contamination profiles can reduce preservative performance.
