Science
Mechanism of Action
As a positively charged (cationic) polymer, Polyquaternium-66 functions by establishing electrostatic attractions with negatively charged biological substrates, such as the stratum corneum of the skin. This ionic interaction facilitates its role as a film former and an antistatic agent, potentially modulating surface characteristics and mitigating static charge accumulation.

While precise stability data for Polyquaternium-66 is currently unavailable, other polyquaternium polymers are generally recognized for their stability across a wide pH range.
Safety
Safety Profile
Polyquaternium-66 has not undergone specific safety assessments by the Cosmetic Ingredient Review (CIR) Expert Panel or the SCCS. However, several other members of the polyquaternium class, such as Polyquaternium-6, -11, -22, and -39, have been evaluated by CIR and deemed safe for cosmetic use under specified conditions and concentrations. FDA status for its use in cosmetics is not specifically available.
