Science
Mechanism of Action
Operating as a biomimetic ingredient, SODIUM SAFFLOWEROYL HYDROLYZED SOY PROTEIN introduces short-chain peptides and amino acids that emulate the skin's Natural Moisturizing Factors (NMF), effectively replenishing moisture and establishing a resilient hydration network on the skin's surface. These molecules function as potent humectants, attracting and locking in water to elevate skin hydration, promoting a visibly softer and smoother complexion. Furthermore, its soy-derived peptides actively reinforce the stratum corneum, substantially reducing transepidermal water loss (TEWL) and bolstering the skin's intrinsic barrier function. It can also form a lightweight protective film through interaction with skin proteins. Crucially, its inherent soy peptides and isoflavones exhibit robust antioxidant properties, actively neutralizing free radicals and mitigating oxidative stress, with smaller protein particles offering deeper nourishing care.

Key findings
- 01 Hydrolyzed soy protein is clinically supported to boost hydration, barrier function, and elasticity in the skin.
- 02 Soy-derived peptides reinforce the stratum corneum, helping to limit transepidermal water loss (TEWL) and improving barrier function, which is crucial for dry, sensitive, or compromised skin.
- 03 Soy peptides and isoflavones demonstrate antioxidant activity, scavenging free radicals and reducing oxidative stress.

Formulation
Stability
This ingredient should be incorporated into the water phase of emulsions. For optimal stability, it is advised to avoid temperatures exceeding 40°C. While exhibiting good solubility between pH 3.0 and 9.0, maximum solubility for certain hydrolysates is observed at pH 7-8, and it's generally best to avoid its isoelectric point, typically between pH 4.0 and 5.0.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed soy proteins and peptides, including Hydrolyzed Soy Protein, safe for cosmetic use within current practices and concentrations, up to 25%. Despite soy proteins being known food allergens, dermal exposure in cosmetics is not expected to elicit allergic reactions due to their water solubility, minimal skin penetration, and molecular weights that are significantly below those required for IgE-binding. Comprehensive studies have consistently reported no skin irritation or allergic reactions in both animal and human subjects at concentrations up to 25%.
