Science
Mechanism of Action
This polymer primarily operates as a humectant, attracting and retaining moisture within the skin to boost hydration and support a balanced moisture barrier. As an emollient, it helps to soften and smooth the skin by filling microscopic gaps between skin cells, thereby forming a protective layer that mitigates moisture loss and shields against environmental stressors. Additionally, it acts as a film-forming agent, creating an ultra-thin, continuous film on the skin's surface, which can help limit damage from external elements like chemicals, UV rays, and pollution. It also possesses antistatic properties, reducing static electricity buildup.

Verdict
While mechanistically promising for hydration and barrier support on the skin, Polyquaternium-98 is rated 'insufficient-data' due to the absence of specific clinical efficacy studies for skin application and a formal CIR safety review.
