An electroanalytical method was developed to detect and quantify the sunscreen agent octocrylene (OCR) in cosmetic products. The method was based on electrochemical reduction, using voltammetric techniques. OCR was reduced at –0.97 V vs. Ag/AgCl on a glassy carbon electrode using a mixture of Britton–Robinson buffer (0.04 mol L−1) and ethanol (7:3, v/v) as the supporting electrolyte solution. Under optimized conditions and square-wave voltammetry, OCR response was linear from 5.0×10−6 to 8.0×10−5 mol L−1 (r = 0.9995), with a limit of detection of 2.8×10−6 mol L−1. The proposed electroanalytical method ...
