Photodecomposition of several compounds commonly used as sunscreen agents
Journal of Photochemistry and Photobiology A: Chemistry, 1994Abstract The photolysis reactions of three compounds commonly used as a sunscreen agents, Parsol 1789 (1-[4-(1,1-dimethylethyl)phenyl]-3-(4-methoxyphenyl)-1,3- propanedione), Oxybenzone ((2-hydroxy-4-methoxyphenyl)phenyl-methanone) and Padimate O (2-ethylhexyl-4-(dimethylamino)benzoate), were investigated to provide a chemical background to aid in ...

Polarographic determination of sunscreen agents in cosmetic products in micellar media
Talanta, 2006This paper introduces a simple, fast and reliable electroanalytical method for differential-pulse polarography based on electrochemical reduction at a dropping mercury electrode. The method was validated for the determination of 2-ethylhexyl-4-methoxycinnamate (EHMC) alone and in association with 4-methylbenzylidene camphor (MBC) or 2-hydroxy-4 ...

Voltammetric Behavior of Sunscreen Agents at Mercury Film Electrode
Electroanalysis, 2002The voltammetric behavior of sunscreen agents on glassy carbon and mercury film electrodes was investigated in aqueous media containing various supporting electrolytes. The possible reaction mechanisms were discussed by the relations of pH values and peak potentials and currents.
