Science
Mechanism of Action
Acting as both a skin and hair conditioning agent, this copolymer forms a supportive film that contributes to improved skin barrier function and hydration. The hydrolyzed wheat protein component imparts moisturizing and conditioning benefits, while the ethyltrimonium chloride methacrylate reinforces its film-forming capacity, helping to prevent trans-epidermal water loss and improve skin's resilience.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deems components of this copolymer, hydrolyzed wheat protein and hydrolyzed wheat gluten, safe for cosmetic use when specific formulation restrictions are met. Peptides must be controlled to a weight-average molecular weight (MW) of 3500 Da or less, or limited to lengths not exceeding 30 amino acids (approximately 3.3 kDa). Adherence to these guidelines minimizes the risk of Type 1 immediate hypersensitivity reactions. The maximum reported use concentration for Hydrolyzed Wheat Protein is 1.7% in rinse-off, non-coloring hair products. While generally safe for topical application, caution is advised for individuals with known wheat allergies or very sensitive skin. This ingredient should not be applied to damaged skin, nor used in products intended for mucous membrane contact or incidental inhalation.
