Hydroxypropyltrimonium Hyaluronate
Hydroxypropyltrimonium HyaluronateHydrator
A positively-charged hyaluronic acid derivative used as a substantive, film-forming humectant.
What it does
Hydroxypropyltrimonium Hyaluronate is hyaluronic acid carrying a positive (cationic) group, which helps it cling to the slightly negative skin and hair surface. It binds water and forms a longer-lasting film, so it is used as a substantive humectant and conditioner. It is a hydration-and-texture ingredient rather than a skin active.
