Hydrolyzed Soy Protein ●
TL;DR. This ingredient is a water-binding conditioning agent and film-former used to improve the feel of hair and skin. In hair care, it can temporarily support smoothness, combability, and a fuller feel by depositing small peptides on the fiber surface.
What does Hydrolyzed Soy Protein do in a cosmetic formula?
This ingredient is a water-binding conditioning agent and film-former used to improve the feel of hair and skin. In hair care, it can temporarily support smoothness, combability, and a fuller feel by depositing small peptides on the fiber surface.
Is Hydrolyzed Soy Protein clean?
This material is generally well accepted in clean-beauty frameworks and is not a common restricted-list issue. The main caveat is sensitivity to the source crop, although hydrolysis usually reduces intact it content.
Is Hydrolyzed Soy Protein sustainable?
This ingredient is plant-derived from an agricultural crop and is generally expected to be biodegradable. Sustainability depends on farming practices, traceability, and whether the crop is conventionally grown, identity-preserved, or certified organic.
Is Hydrolyzed Soy Protein COSMOS-approved?
It is permitted under COSMOS-natural and can be used in COSMOS-organic formulas when the feedstock and processing aids meet the standard’s requirements. It fits Green Chemistry reasonably well because it uses renewable biomass and produces readily biodegradable peptide mixtures, especially when made by enzymatic hydrolysis.
How does Hydrolyzed Soy Protein work chemically?
The material is a water-soluble mixture of peptides and free amino acids created by cleaving larger storage proteins into lower-molecular-weight fragments. Typical use levels are often about 0.1% to 5%, with performance influenced by molecular weight distribution, pH, electrolyte load, and compatibility with cationic conditioning systems.
