Kombucha ●
TL;DR. This ingredient is used as a skin-conditioning botanical ferment, often added for antioxidant support, mild exfoliating acidity, and a smoother skin feel. It can also contribute light humectant effects depending on the extract format.
What does Kombucha do in a cosmetic formula?
This ingredient is used as a skin-conditioning botanical ferment, often added for antioxidant support, mild exfoliating acidity, and a smoother skin feel. It can also contribute light humectant effects depending on the extract format.
Is Kombucha clean?
It generally has a low clean-beauty concern profile and is not a common restricted-list ingredient. Sensitivity risk depends on final pH, residual organic acids, and how well the ferment is purified and preserved.
Is Kombucha sustainable?
This material is typically made from renewable agricultural inputs through aqueous fermentation, which is favorable from a Green Chemistry perspective. It is expected to be readily biodegradable, with the main sustainability variables coming from crop sourcing, water use, and preservation system choices.
Is Kombucha COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic standards when the fermentation feedstocks, processing aids, solvents, and preservatives are compliant. Its fit is strongest when made by low-energy fermentation from renewable inputs without non-compliant solvents or synthetic additives.
How does Kombucha work chemically?
The molecule profile is not singular, because this is a complex ferment containing organic acids, polyphenols, sugars, minerals, and trace fermentation metabolites. In formulas it is usually used as an aqueous extract at low single-digit percentages, and performance and skin feel are strongly influenced by final product pH and preservative compatibility.
