About QUATERNIUM-22

A conditioning agent mainly for hair — tames static, adds softness, and improves manageability. CIR-reviewed and considered safe.

Detailed Analysis

Quaternium-22 (CAS 51812-80-7) is a quaternary ammonium compound functioning as an antistatic agent, film former, and hair fixative in cosmetic formulations, primarily used in rinse-off hair products at concentrations up to 2%. The CIR Expert Panel concluded it is safe in current practices of use. As a large, highly polar molecule, it is unlikely to be absorbed through the skin, minimizing systemic toxicity risk. It showed no skin irritation or sensitization in available studies. It is non-genotoxic in bacterial assays. Unreacted monomer content is low and not a toxicological concern.
