Saccharomyces/Black Tea Ferment

TL;DR. This ingredient primarily acts as a skin-conditioning botanical it, adding water-soluble antioxidants, mild organic acids, and humectant-like components to formulas.

What does Saccharomyces/Black Tea Ferment do in a cosmetic formula?

This ingredient primarily acts as a skin-conditioning botanical it, adding water-soluble antioxidants, mild organic acids, and humectant-like components to formulas.

Is Saccharomyces/Black Tea Ferment clean?

From a clean-beauty perspective, it is generally well accepted when properly preserved and manufactured with good microbial controls. The main watchpoints are batch consistency, residual fragrance-like botanical compounds, and rare sensitivity to fermentation-derived proteins or acids.

Is Saccharomyces/Black Tea Ferment sustainable?

It is typically made from renewable agricultural feedstocks through aqueous fermentation, and its water-soluble components are expected to be readily biodegradable. Sustainability depends mainly on agricultural sourcing quality, water use, and the preservative system used in the supplied raw material.

Is Saccharomyces/Black Tea Ferment COSMOS-approved?

It can be permitted under COSMOS-natural and COSMOS-organic when made by approved fermentation and extraction processes and preserved with compliant materials. It fits Green Chemistry well because fermentation is a low-temperature bioprocess using renewable inputs, though the final rating depends on the full raw-material composition.

How does Saccharomyces/Black Tea Ferment work chemically?

This material is not a single molecule, it is an aqueous fermentation complex containing polyphenols, organic acids, sugars, minerals, and small microbial metabolites. It is commonly used in the water phase at low single-digit percentages, often around 1 to 5%, and is best formulated within the supplier’s stated pH and heat-stability limits.
