Science
Mechanism of Action
This ingredient operates through dual mechanisms to optimize skin hydration. Firstly, it forms a protective, moisture-sealing film on the skin's surface, effectively minimizing transepidermal water loss. Secondly, its humectant nature allows it to attract and bind atmospheric water, delivering sustained hydration. The smaller peptide molecules are also thought to penetrate the skin, supporting epidermal repair processes, and it may mitigate irritation caused by surfactants.

Key findings
- 01 The Cosmetic Ingredient Review (CIR) has noted a maximum use concentration for Hydrolyzed Wheat Gluten in cosmetics ranging from 0.005% to 0.09%, with the upper limit specifically for eye makeup preparations.
- 02 Safety assessments highlight that formulations restricting peptide molecular weight to 3500 Da or less (or not exceeding 30 amino acids) are crucial to prevent Type 1 immediate hypersensitivity reactions, especially considering higher molecular weight hydrolysates (40-50 kDa) have been associated with such reactions.

The Formula
Formulation
Stability
Hydrolysis significantly improves the solubility of wheat gluten, allowing its solubility profile to become largely independent of pH within typical cosmetic ranges.
Conflicts
- Formulations containing peptides with a molecular weight exceeding 3500 Da (or greater than 30 amino acids) due to an elevated risk of Type 1 hypersensitivity reactions.
- Application on compromised or damaged skin.
- In products intended for mucous membrane contact.
- In aerosolized cosmetic products where incidental inhalation is possible.
Safety
Safety Profile
The CIR Expert Panel deems Hydrolyzed Wheat Gluten safe for cosmetic use, provided it adheres to strict formulation guidelines: peptide lengths must be minimized (below 3500 Da or 30 amino acids) to avoid Type 1 immediate hypersensitivity. Furthermore, it should not be applied to damaged skin, included in products that may contact mucous membranes, or used in aerosolized products. Individuals with known gluten sensitivity or celiac disease are advised to avoid this ingredient.

Verdict
Hydrolyzed Wheat Gluten Extract offers significant moisturizing and skin conditioning benefits, particularly for dry and normal skin types, but requires precise formulation to ensure safety and prevent hypersensitivity reactions.
