Ferment ●
TL;DR. This ingredient is usually used as a skin-conditioning bioactive, contributing small metabolites that can support hydration, softness, and overall product feel. It is not typically the primary emulsifier, surfactant, or preservative in a formula.
What does Ferment do in a cosmetic formula?
This ingredient is usually used as a skin-conditioning bioactive, contributing small metabolites that can support hydration, softness, and overall product feel. It is not typically the primary emulsifier, surfactant, or preservative in a formula.
Is Ferment clean?
From a clean-beauty perspective, it is generally acceptable when the supplier provides clear composition, microbial-limit testing, and residue controls. The main caveat is variability, since the exact substrate, organism, preservatives, and trace byproducts can differ by supplier.
Is Ferment sustainable?
This material is often made through microbial conversion of plant-derived sugars or botanical substrates, which can fit a lower-impact sourcing profile. Biodegradability is usually favorable, but the overall footprint depends on the feedstock, processing inputs, water use, and preservation system.
Is Ferment COSMOS-approved?
It may be permitted under COSMOS-natural or COSMOS-organic when made from allowed natural substrates with approved processing aids and non-GMO production controls. Its Green Chemistry fit is strongest when renewable feedstocks, aqueous processing, and readily biodegradable outputs are documented.
How does Ferment work chemically?
This material is a complex, water-based mixture rather than a single molecule, typically containing organic acids, peptides, amino acids, sugars, minerals, and other low-molecular-weight metabolites. Composition, pH, and use level are supplier-specific, so formulators usually confirm preservative compatibility, microbial limits, odor, color, and batch-to-batch consistency.
