Science
Mechanism of Action
This complex works synergistically to optimize skin health. Hydrolyzed soy protein and vegetable amino acids serve as powerful humectants, actively drawing and retaining moisture within the skin's outermost layers. This action replenishes Natural Moisturizing Factors (NMFs), vital for maintaining skin softness, smoothness, and overall suppleness. Soy-derived peptides strengthen the stratum corneum, the skin's outer protective barrier, which effectively minimizes transepidermal water loss (TEWL) and bolsters barrier integrity. These components also form a lightweight protective film on the skin, offering a shield against environmental aggressors and irritants. Additionally, lysine, an essential amino acid, plays a crucial role in promoting collagen synthesis, supporting natural healing processes, and enhancing skin elasticity and protective functions.

Stability
For optimal stability, this blend, particularly its hydrolyzed soy protein component, performs best within a pH range of 4.0-7.0. While enzymatic hydrolysis during its production may occur at very acidic pH (1.5-3.5), enzymes are typically deactivated by adjusting to pH 7.0 for finished product stability.
Safety
Safety Profile
The CIR Expert Panel determined soy proteins and peptides, including Hydrolyzed Soy Protein, are safe for cosmetic use within current industry practices and concentrations. Studies have shown no evidence of skin irritation or allergic reactions in animal or human subjects, with no Type I allergic reactions reported from cosmetic use of hydrolyzed soy protein up to 25%. It exhibited no dermal sensitizing or mutagenic effects up to 25%. While this specific blend (a hydroxypropyl trimethylammonium derivative of hydrolyzed soy protein and amino acids) has not been individually reviewed by CIR/SCCS, the safety of its primary components is well-established. The FDA classifies peptones as Generally Recognized As Safe (GRAS) for direct food contact. EWG Skin Deep assesses the ingredient with a 'LOW' hazard rating for cancer, allergies & immunotoxicity, and developmental and reproductive toxicity concerns.
