Hydrolyzed Yeast Protein ●
TL;DR. This ingredient is used as a skin and hair conditioning agent, adding light humectancy, softness, and a subtle film-forming effect. In hair care, it can help improve feel, manageability, and the look of damaged fibers.
What does Hydrolyzed Yeast Protein do in a cosmetic formula?

Is Hydrolyzed Yeast Protein clean?
Clean-beauty frameworks generally view it as low-concern when it is well purified and preserved with accepted systems. The main watchpoint is individual sensitivity, which can occur with some it-derived conditioning materials.
Is Hydrolyzed Yeast Protein sustainable?
It is typically made from fermentation biomass, often linked to brewing or biotech streams, which gives it a relatively efficient renewable-source profile. It is water-soluble and expected to be readily biodegradable, with low persistence concerns.
Is Hydrolyzed Yeast Protein COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when the source material, processing aids, and preservative system meet the standard. From a Green Chemistry lens, it fits well because it can use renewable fermentation feedstock, water-based processing, and biodegradable chemistry.
How does Hydrolyzed Yeast Protein work chemically?
The molecule profile is a polydisperse, water-soluble blend of peptides and free amino acids with amide, carboxyl, hydroxyl, and amine groups that support water binding and surface deposition. It is commonly used at about 0.1% to 5% as supplied, performs best in aqueous systems around mildly acidic to neutral pH, and may darken or develop odor under high heat or reactive reducing-sugar conditions.
