Hydrolysed Soy Protein ●
TL;DR. This ingredient is a conditioning and film-forming agent for hair and skin, helping improve feel, combability, and temporary smoothness. It can also act as a mild humectant by binding water at the surface.
What does Hydrolysed Soy Protein do in a cosmetic formula?
This ingredient is a conditioning and film-forming agent for hair and skin, helping improve feel, combability, and temporary smoothness. It can also act as a mild humectant by binding water at the surface.
Is Hydrolysed Soy Protein clean?
Clean-beauty frameworks generally treat it as low-concern and not a common restricted-list ingredient. The main flags are source transparency, residual processing impurities, and rare sensitivity in people reactive to its botanical source.
Is Hydrolysed Soy Protein sustainable?
It is made from a renewable crop-derived feedstock and is expected to biodegrade more readily than persistent synthetic films. Sustainability depends on agricultural practices, land use, and whether suppliers document non-GMO or responsible sourcing.
Is Hydrolysed Soy Protein COSMOS-approved?
It can fit COSMOS-natural and COSMOS-organic formulas when made from permitted plant feedstock using allowed processing aids, with organic status dependent on certified input material. Its Green Chemistry profile is favorable because it uses renewable biomass and gives a biodegradable, water-compatible functional material, though processing and purification details matter.
How does Hydrolysed Soy Protein work chemically?
Chemically, this material is a water-soluble mixture of short plant peptides and amino acids formed by breaking larger storage macromolecules into smaller fragments. It is typically used around 0.1% to 5% in leave-on and rinse-off products, is most compatible with aqueous systems, and can interact with cationic conditioners, salts, or strong extremes of pH.
