Science
Mechanism of Action
Operating as a surface-active agent, Hydroxypropyltrimonium Maltodextrin Crosspolymer reduces the interfacial tension of liquids, enabling immiscible substances like oil and water to combine. This property facilitates the removal of fat and soil particles, contributing to effective cleansing. While the crosspolymer's direct mechanism for hydration is not extensively detailed, its maltodextrin derivative is known for its capacity to bind moisture, penetrate skin for hydration, and form a protective film to lock in water.
