Science

Mechanism of Action

Operating as a comprehensive skin conditioner, this extract delivers a complex of active components including isoflavones, essential amino acids, and lecithin. These elements collectively support the endogenous production of collagen and elastin, facilitate dermal repair processes, and significantly improve the skin's capacity for moisture retention. Its peptide constituents are known to emulate natural moisturizing factors (NMFs), establishing a robust, moisture-retentive network on the skin surface while providing antioxidant defense against environmental stressors.

Stability

Hydrolyzed soy proteins exhibit optimal solubility at acidic pH values (e.g., pH 2) and neutral to alkaline ranges (e.g., pH 7.0, pH 10). Solubility decreases around the isoelectric point, typically between pH 4 and 5.5. Thermal stability may be reduced at lower pH values.

The Cosmetic Ingredient Review (CIR) Expert Panel deemed related hydrolyzed soy proteins and peptides, including 'Hydrolyzed Soy Protein Extract,' safe for cosmetic use in 2015. These compounds are water-soluble and exhibit minimal skin penetration, significantly mitigating concerns regarding dermal allergic reactions in individuals with food-related soy sensitivities. Testing up to 25% 'hydrolyzed soy protein' showed no irritation or allergic reactions in human subjects. The highest reported concentration of use for a related ingredient is 3.5% in mascara. However, a singular case report noted rosacea aggravation in one patient using soy-containing facial products.
