Science
Mechanism of Action
As a highly charged cationic polymer, Polyquaternium-6 effectively adheres to the skin's surface, forming a protective film. This action contributes to reduced transepidermal water loss, thereby boosting moisturization and mitigating the sensation of dryness or tightness often experienced after cleansing. It functions as a conditioning agent, delivering a desirable smooth and lubricious tactile experience while facilitating effortless product application. In cleansing formulations, it also plays a role in enhancing and stabilizing foam quality.
