Yeast Extract/Extrait De Levure ●
TL;DR. This ingredient primarily functions as a skin-conditioning and humectant active, adding amino acids, peptides, sugars, minerals, and B-vitamin-type components that support feel and hydration claims. It can also contribute antioxidant-support and calming-positioning claims, depending on the extract profile.
What does Yeast Extract/Extrait De Levure do in a cosmetic formula?

It can also contribute antioxidant-support and calming-positioning claims, depending on the extract profile.
Is Yeast Extract/Extrait De Levure clean?
From a clean-beauty perspective, it is generally well tolerated and not a common restricted-list material. Because it is a complex biological extract, brands should control residual proteins, bioburden, preservatives, and fermentation substrate quality.
Is Yeast Extract/Extrait De Levure sustainable?
It is typically produced by fermentation on sugar-rich renewable feedstocks, followed by extraction or autolysis and filtration. The water-soluble constituents are expected to be readily biodegradable, with sustainability depending mainly on energy use, substrate sourcing, and wastewater management.
Is Yeast Extract/Extrait De Levure COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when made from non-GMO inputs and processed with approved extraction methods. Its fermentation-based origin, aqueous processing options, and biodegradability fit Green Chemistry principles well.
How does Yeast Extract/Extrait De Levure work chemically?
This material is a water-soluble mixture of amino acids, short peptides, carbohydrates, nucleotides, minerals, and small metabolites rather than a single molecule. It is usually used at low cosmetic active levels, is most comfortable in water-based systems, and should be preserved well because nutrient-rich extracts can support microbial growth if the formula is not adequately protected.
