Science
Mechanism of Action
This hydrolyzed protein derivative, characterized by its carefully optimized smaller molecular weight, facilitates deep dermal penetration to deliver profound hydration and contribute to the structural repair of compromised skin. It actively forms a subtle, protective barrier on the skin's surface, which effectively mitigates trans-epidermal water loss and offers a robust defense against environmental aggressors. Furthermore, it demonstrates antioxidant capabilities against free radicals and contributes to the stability of emulsion formulations.

Stability
Optimal stability is observed within a precise pH range of 4.5 to 5.0, reflecting similar characteristics to its parent hydrolyzed wheat protein.
Conflicts
- Formulations containing higher molecular weight peptides (exceeding 3500 Daltons or approximately 30 amino acids), or those used on compromised skin, or in conjunction with strong surfactants like Sodium Dodecyl Sulfate (SDS), may significantly elevate sensitization risk.
- Avoid incorporation into products designed for incidental inhalation (e.g., sprays) or those that may contact mucous membranes or damaged skin.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded this ingredient is safe for use in cosmetics when formulated to strictly limit peptide weight-average molecular weight (MW) to 3500 Daltons or less (approximately 30 amino acids). However, higher molecular weight forms of hydrolyzed wheat protein (40-50 kDa) have been linked to Type 1 hypersensitivity reactions (including contact urticaria and anaphylactic shock) in cosmetic products, particularly when applied to damaged skin or when co-formulated with surfactants. At precisely controlled, lower molecular weights (e.g., 350 Da), it is generally not considered a significant dermal or ocular irritant.
