Science
Mechanism of Action
This ingredient primarily modifies the viscosity of cosmetic formulations, enabling desired product flow and feel. Generally, polyquaterniums are cationic polymers that form a bond with the negatively charged surfaces of the skin. This interaction can provide conditioning benefits, draw moisture from the environment into the skin (humectancy), and establish a protective film that helps reduce transepidermal water loss and defend against environmental stressors, leading to skin that feels smoother and more conditioned.

Safety Profile
While POLYQUATERNIUM CROSSPOLYMER-3 specifically has not been reviewed by regulatory bodies like CIR, SCCS, or FDA, other polyquaternium compounds have established safety profiles. For example, Polyquaternium-11 was deemed safe for use in concentrations up to 50% in hair care, while Polyquaternium-22 and Polyquaternium-39 were considered safe at concentrations up to 2% and 3% respectively in cosmetic formulations. The lack of specific assessment for this exact crosspolymer means direct safety percentages are unavailable.
