Science
Mechanism of Action
This ingredient functions as a skin conditioning agent and film former. Its low molecular weight allows for penetration into the skin, where it delivers deep hydration, nourishes, soothes, and helps repair damaged structures. By forming a protective film, it aids in preserving the skin's natural moisture balance, enhances elasticity, and protects against environmental stressors, contributing to overall skin health and a refined texture.

Formulation
Stability
Optimal stability and safety are achieved when peptides are meticulously restricted to a weight-average molecular weight of 3500 Da or less, with individual polypeptide lengths not exceeding 30 amino acids. This precision formulation is critical to prevent potential sensitization.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deems Hydrolyzed Wheat Protein safe for cosmetic use, provided strict molecular weight controls are maintained (≤ 3500 Da, ≤ 30 amino acids) to mitigate sensitization risks. While low molecular weight variants (e.g., MW 350 Da) have shown no irritation in studies, higher molecular weight forms (40,000-50,000 Da) have been linked to Type 1 immediate hypersensitivity reactions. The maximum concentration reported in CIR surveys for Hydrolyzed Wheat Protein in rinse-off hair products was 1.7%. EWG Skin Deep generally lists this ingredient with low concerns for cancer, allergies, and reproductive toxicity.
