Polyquaternium-28
Polyquaternium-28 is a high-performance cationic copolymer, meticulously engineered to be a cornerstone ingredient in advanced hair care formulations. Its primary function is to deliver an unparalleled combination of conditioning, detangling, and frizz control by leveraging its strong electrostatic affinity for hair. Hair fibers naturally carry a negative charge, and as a cationic polymer, Polyquaternium-28 is powerfully attracted to them. Upon application, it deposits evenly onto the hair shaft, forming a smooth, continuous film that effectively smoothes the cuticle layer.
This mechanism is responsible for its core benefits: a dramatic reduction in surface friction for effortless wet and dry combing, which directly translates to less breakage and damage. It imparts an immediate sensation of exceptional softness and silkiness without any undesirable buildup or a heavy, greasy feel. Furthermore, this protective polymer layer acts as a potent anti-static and anti-humidity shield, effectively neutralizing flyaways and locking out moisture to provide resilient, long-lasting frizz control even in challenging environments.
A significant technical advantage of Polyquaternium-28 is its outstanding formulation flexibility. It exhibits remarkable clarity and stability across a broad pH range and is highly compatible with various surfactant systems, including anionic ones commonly found in shampoos and body washes.
