Science
Mechanism of Action
As a cationic polymer, Polyquaternium-86 carries a positive charge, enabling it to ionically bond with the negatively charged surfaces of skin and hair. On the skin, it creates a protective barrier that mitigates transepidermal water loss, thereby improving hydration. This film also interacts with keratin proteins within skin cells, which can contribute to a softer and smoother skin feel.

Polyquaternium-86, like other polyquaterniums, is expected to exhibit high stability across a broad spectrum of pH values and various environmental conditions.
Safety
Safety Profile
Polyquaternium-86 has not undergone a specific safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel. However, the CIR has deemed several other polyquaternium ingredients (e.g., Polyquaternium-6, Polyquaternium-11, Polyquaternium-22, Polyquaternium-39) safe for use in cosmetics at current concentrations. The CIR emphasizes the importance of understanding the residual monomer/polymerization profiles for all polyquaternium ingredients. No specific SCCS opinion or FDA status for Polyquaternium-86 has been identified.
