AB  - A simple, precise and sensitive reverse-phase high performance liquid chromatographic (RP-HPLC) method has been developed for the quantitation of bifonazole, an imidazole antifungal, simultaneously with benzyl alcohol, used as preservative, in pharmaceutical formulations. Method employed Zorbax Eclipse XDB-C18 (250x4.6 mm i.d., 5 mu m) column, methanol-ammonium acetate (pH 2; 65 mM) (65:35, v/v, pH(*) 3.6) as mobile phase with flow rate of 1 mL min(-1) and variable UV detection at 220 and 252 nm. The proposed method was validated by testing its linearity, selectivity, recovery, repeatability, LOD/LOQ values and it was successfully employed for the determination of bifonazole and benzyl alcohol in pharmaceutical cream-based formulations.

AB  - The influence of the anionic surfactant sodium dodecyl sulfate on the rate of the reaction between the cationic form of Nile Blue A and hydrogen peroxide was investigated in the pH range from 5 to 8.5. A retardation of the oxidation of Nile Blue A with hydrogen peroxide of three orders of magnitude was observed at pH 8.5 in the presence of anionic micelles compared to the kinetic data in water. The retardation effect was less pronounced at lower pH values. These effects were explained by the electrostatic interaction of the species involved in the reaction with the negatively charged micellar surface and their effective separation in the vicinity of the micellar surface.
