Quaternized versions of a protein are generally many times more substantive than the parent protein hydrolyzate. Quaternized protein has a more binding effect due to its additional bonds which create a stronger cationic character, thus a more intense bond of the protein to the hair shaft. This also enhances the moisture-binding properties of the protein which is another important benefit. Compared to regular hydrolyzed proteins, quaternized proteins possess enhanced moisturizing and conditioning capabilities due to their higher substantivity to hair. Not only does Quaternized Wheat protein impart a powerful moisturizing effect, but it also aids in the repair of damaged hair because of its Cysteine content.
