Yeast Extract ●
TL;DR. This ingredient is used primarily as a skin-conditioning and humectant ingredient, contributing amino acids, peptides, sugars, minerals, and B-vitamin components that support a hydrated feel and smoother skin texture.
What does Yeast Extract do in a cosmetic formula?
This ingredient is used primarily as a skin-conditioning and humectant ingredient, contributing amino acids, peptides, sugars, minerals, and B-vitamin components that support a hydrated feel and smoother skin texture.
Is Yeast Extract clean?
From a clean-beauty perspective, it is generally well accepted and not a common restricted-list concern. Sensitivity is uncommon, though protein-rich natural extracts can be less predictable for very reactive skin than single-molecule ingredients.
Is Yeast Extract sustainable?
This material is typically fermentation-derived from renewable carbohydrate feedstocks and is expected to be readily biodegradable. Its footprint depends on the feedstock, fermentation energy use, and downstream concentration or drying steps.
Is Yeast Extract COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic frameworks when produced by permitted fermentation, extraction, and processing methods. It fits Green Chemistry reasonably well through renewable inputs, aqueous processing, and good biodegradability.
How does Yeast Extract work chemically?
The material is a complex aqueous-soluble mixture of amino acids, short peptides, polysaccharides, nucleotides, minerals, and vitamin-like compounds rather than a single defined molecule. Typical use levels are often around 0.1% to 5%, and formulas need adequate preservation because nutrient-rich extracts can increase microbial growth pressure.
