Yeast Ferment Extract ●
TL;DR. This ingredient is mainly a skin-conditioning and humectant material, used to improve skin feel and add water-binding components. It can also contribute amino acids, peptides, sugars, minerals, and other small molecules that support a formula’s sensorial and conditioning profile.
What does Yeast Ferment Extract do in a cosmetic formula?
This ingredient is mainly a skin-conditioning and humectant material, used to improve skin feel and add water-binding components. It can also contribute amino acids, peptides, sugars, minerals, and other small molecules that support a formula’s sensorial and conditioning profile.
Is Yeast Ferment Extract clean?
From a clean-beauty perspective, it is usually low-friction when the supplier controls residual solvents, preservatives, heavy metals, and microbial quality. Because it is a complex biological material, very sensitive users may react, but it is not a common restricted-list ingredient.
Is Yeast Ferment Extract sustainable?
It is typically produced from renewable carbohydrate feedstocks through microbial bioprocessing, which can be relatively resource-efficient compared with many petrochemical routes. The soluble organic fraction is expected to be biodegradable, while the footprint depends on feedstock sourcing, energy use, water management, and preservation system.
Is Yeast Ferment Extract COSMOS-approved?
It is generally compatible with COSMOS-natural and can be used in COSMOS-organic formulas when the substrate, processing aids, extraction method, and preservation system meet the standard. Its Green Chemistry fit is strong when made with renewable inputs, aqueous processing, mild conditions, and biodegradable outputs.
How does Yeast Ferment Extract work chemically?
This material is a complex aqueous mixture rather than a single molecule, typically containing low-molecular-weight peptides, free amino acids, carbohydrates, organic acids, vitamins, minerals, and nucleotide fragments. It is commonly used at low single-digit percentages, is usually formulated in the skin-compatible pH range, and requires adequate preservation because the nutrient-rich matrix can support microbial growth.
