Science
Mechanism of Action
As a highly charged cationic copolymer, Polyquaternium-22's positively charged molecules readily adhere to the negatively charged surface of human skin. This interaction forms a protective, flexible film on the skin's surface, which provides a smooth, lubricious feel, diminishes the sensation of skin tightness after cleansing or drying, and actively contributes to skin moisturization. This film also aids in the effortless application of skincare formulations.

Exhibits exceptional stability across a broad pH spectrum, from highly acidic (pH 1) to highly alkaline (pH 14).
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Polyquaternium-22 as safe for use in cosmetic formulations, particularly at concentrations up to 2% in rinse-off products. The large, highly polar molecular structure of this polymer minimizes the likelihood of skin absorption, thereby reducing concerns for local or systemic toxicity. Unreacted monomer content is considered negligible.
