Aminopropyl Dimethicone
Aminopropyl Dimethicone is a silicone compound belonging to the silicones and siloxanes family, specifically a dimethyl siloxane with 3-aminopropyl methyl and trimethylsilyl termination (CAS #: 99363-37-8). It is an amino-functional silicone, meaning it carries amine groups that allow it to bind more substantively to hair fibers compared to non-functional silicones. It is widely used in leave-in treatments, conditioners, hair masks, and serums. Its official CosIng-listed function is hair conditioning.
Aminopropyl Dimethicone conditions hair by coating the hair fiber, helping to improve smoothness, manageability, and shine. The amino functional groups enhance substantivity to damaged or chemically treated hair, allowing for targeted deposition where the hair needs it most.
