Science
Mechanism of Action
This ingredient operates as a cationic polymer, forming an electrostatic bond with negatively charged surfaces such as hair and skin. It creates a protective, hydrophobic film that resists rinse-off. In hair, this film effectively minimizes water absorption, protects against surfactant-induced stripping, and helps preserve color. For skin, a similar film-forming and conditioning effect is theoretically plausible, though specific dermal outcomes are not detailed in the available research.
