POLYQUATERNIUM-67.

Valuable CAS - / ANTISTATIC, FILM FORMING, HAIR CONDITIONING

Polyquaternium-67 is a high-performance cationic polymer designed to enhance skin hydration and reinforce its protective barrier. It functions as a potent humectant and film-former, while precisely optimizing the delivery of other beneficial active ingredients to the skin.

Humectant Film-forming Antistatic Hair conditioning Active deposition enhancer Moisture retention

Science

Mechanism of Action

This polymer operates through its cationic nature, allowing it to electrostatically bind with the negatively charged surface of the skin. This interaction forms a subtle, protective film that resists rinse-off, effectively locking in moisture and significantly improving skin hydration. Furthermore, its film-forming properties actively enhance the deposition of beneficial compounds, such as occlusive moisturizers and sunscreens, from cleansing formulations onto the skin.
