HYDROLYZED SOY PROTEIN.

Valuable CAS 68607-88-5 / ANTISTATIC, HAIR CONDITIONING, HUMECTANT, SKIN CONDITIONING

Hydrolyzed Soy Protein is a sophisticated, plant-derived ingredient processed to yield beneficial peptides and amino acids. It is recognized for its potent hydrating properties, capacity to stimulate skin regeneration, and protective antioxidant benefits.

Summary

Humectant Skin Conditioning Antioxidant Anti-aging Barrier Support Collagen Boosting Hyaluronic Acid Stimulation Cell Renewal

Science

Mechanism of Action

This ingredient functions as a highly effective humectant, drawing and retaining moisture within the stratum corneum to significantly enhance skin hydration, resulting in a smoother, more supple texture. Its bio-active peptides and isoflavones actively stimulate collagen synthesis and trigger the skin's endogenous hyaluronic acid production, crucial for improving skin integrity and reducing the appearance of fine lines and wrinkles. Furthermore, it delivers antioxidant protection, neutralizing free radicals and mitigating oxidative stress and photoaging caused by UVB radiation. It fortifies the skin barrier, minimizing transepidermal water loss (TEWL), and forms a lightweight protective film against environmental irritants, while also promoting cell renewal to refine skin texture and bolster elasticity.

3.5%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Hydrolyzed Soy Protein as safe for cosmetic applications, with a maximum reported use concentration up to 3.5%. Despite soy being a recognized food allergen, the CIR Panel concluded that its water-soluble nature and molecular weight are insufficient for skin penetration that would induce Type I immediate hypersensitivity reactions. Peptones, a component of hydrolyzed proteins, are also Generally Recognized As Safe (GRAS) by the FDA as direct food substances.
