Hydroxypropyltrimonium Maltodextrin Crosspolymer

What Hydroxypropyltrimonium Maltodextrin Crosspolymer is & what it does

Hydroxypropyltrimonium Maltodextrin Crosspolymer is a film-forming polymer made by cross-linking maltodextrin (a starch-derived sugar) with a cationic hydroxypropyltrimonium group. In formulas it is commonly used as a conditioning and film-forming agent, leaving a light, smooth feel on skin or hair and helping other actives spread more evenly. The cationic charge gives it affinity for skin and hair surfaces, which can improve substantivity. It is generally considered a mild, well-tolerated functional ingredient.
