Hydroxypropyltrimonium hydrolyzed wheat protein
Hydroxypropyltrimonium hydrolyzed wheat protein is a conditioning ingredient derived from wheat that helps smooth and strengthen hair while adding moisture. It is commonly found in shampoos, conditioners, hair masks and some skincare products for its ability to improve texture and manageability. Shoppers looking for gentler, protein-based alternatives to silicones often choose this ingredient.
How it works in skincare
In cosmetics and skincare, hydroxypropyltrimonium hydrolyzed wheat protein forms a light protective film on the surface of hair or skin, helping to lock in moisture and reduce static. The positively charged quaternary ammonium group gives it excellent substantivity, allowing it to bind to negatively charged hair fibres or skin, smoothing the cuticle, improving combability and imparting a soft, silky feel without weighing hair down.
