Science
Mechanism of Action
As a cationic quaternary ammonium compound, Acetamidopropyl Trimonium Chloride is attracted to and binds with negatively charged surfaces such as hair fibers and skin. This interaction allows it to form a protective film, which smooths hair cuticles to reduce frizz, improve manageability, and help retain essential moisture. On the skin, its moisturizing properties contribute to hydration, and it also acts as an antistatic agent to neutralize electrostatic charges.
