Lactobacillus/Salix Purpurea Bark Ferment Filtrate ●
TL;DR. This ingredient is primarily used as a natural-origin antimicrobial preservative booster, helping control microbial growth in water-based formulas. It can also contribute mild skin-conditioning benefits from the fermented botanical extract fraction.
What does Lactobacillus/Salix Purpurea Bark Ferment Filtrate do in a cosmetic formula?
This ingredient is primarily used as a natural-origin antimicrobial preservative booster, helping control microbial growth in water-based formulas. It can also contribute mild skin-conditioning benefits from the fermented botanical extract fraction.
Is Lactobacillus/Salix Purpurea Bark Ferment Filtrate clean?
In clean frameworks, this ingredient is generally viewed as low-concern and naturally derived, with no common restricted-list flag. The main diagnostic caveat is that antimicrobial performance is formula-dependent, so products relying on it need proper challenge testing.
Is Lactobacillus/Salix Purpurea Bark Ferment Filtrate sustainable?
It comes from renewable plant material processed by fermentation and filtration, and the resulting water-soluble mixture is expected to be biodegradable. Supply-chain impact depends on agricultural sourcing and extraction efficiency, but it does not raise the persistence issues associated with silicone or fluorinated materials.
Is Lactobacillus/Salix Purpurea Bark Ferment Filtrate COSMOS-approved?
It is generally compatible with COSMOS-natural and, when inputs and processing meet the standard, COSMOS-organic formulas. It fits Green Chemistry through renewable feedstocks, aqueous fermentation, mild processing, and likely biodegradability, with the practical caveat that preservation efficacy must be proven in the finished product.
How does Lactobacillus/Salix Purpurea Bark Ferment Filtrate work chemically?
This material is not a single molecule, but an aqueous it containing fermentation metabolites plus plant-derived phenolic and organic-acid fractions. Typical use is often in the low single digits, commonly around 2 to 4%, and performance depends on pH, water activity, companion preservatives, and the total bioburden of the formula.
