    Annotation Triton X100 and Brij 35 based self-organized systems (at a concentration of 0.1 M) provide eugenol solubilization in water media. Eugenol is irreversibly oxidized on a glassy carbon electrode at 780 and 700 mV in 0.1 M LiClO4 in 0.1 M Triton X100 and Brij 35 micellar media, respectively. Electrochemicaloxidation of eugenol is a diffusion-controlled process and involves 2.0 electrons corresponding to the formation of o-quinone. The eugenol calibration graph is linear in the range 15-1230 uM with an estimated detection limit of 3.8 uM and a quantification limit of 12.6 uM. The addition of ethanol (10% v/v) to a 0.1 M Triton X100 micellar medium leads to the cathodic shift of eugenol oxidation potential of 50 mV. Under these conditions, the oxidation current linearly depends on the eugenol concentration in the range 0.02-1.0 mM with a detection limit of 0.01 mM. The preliminary extraction of eugenol in essential oils in a Triton X100 micellar medium has been carried out.
