Science
Mechanism of Action
As a member of the polyquaternium class, Polyquaternium-85 possesses a positive charge, enabling it to bond electrostatically with the naturally negatively charged surface of the skin. This interaction leads to the formation of a cohesive, rinse-resistant film. This film actively conditions the skin, helps minimize transepidermal water loss (TEWL) through barrier enhancement, and can offer a degree of protection from external irritants. Additionally, some polyquaterniums are known to exhibit humectant properties, attracting and binding moisture to the skin.

Verdict
While Polyquaternium-85 is theorized to offer film-forming and conditioning benefits, there is currently insufficient specific data regarding its safety and efficacy for a conclusive rating in precision skincare formulations.
