Hydrolized Soya Protein is a plant-derived cosmetic protein obtained from soybean protein and processed through hydrolysis into smaller peptides and amino-acid-containing fractions. This makes it a versatile ingredient for modern hair care, skin care and personal care formulations.
Hydrolyzed Soya Protein is valued for its conditioning, film-forming, moisturizing and hair-care properties. It can help improve the softness, smoothness and manageability of hair while supporting a conditioned and moisturized skin feel.
It is particularly suitable for protein-enriched, plant-based and vegan-positioned cosmetic formulations, subject to the exact source and certification of the commercial grade.
