A novel high-performance liquid chromatography (HPLC) method with 4- N , N -dimethylaminobenzaldehyde as an internal standard was developed for the determination of Camphor with the main goal of facilitating the analysis of different cosmetic and pharmaceutical products that contain Camphor in analytical laboratories. The method can be applied to cosmetic and pharmaceutical samples such as gels, ointments, and creams containing Camphor. Chromatographic separation was carried out on the Symmetry ® C18, 5 μm column (Waters), 250 × 4.6 equipped with guard column E, InertSustain C18, 5 µm, while using the flow of 1.4 mL/min, with a column temperature of 25 °C. The mobile phase consisted of 600 mL of acetonitrile, 400 mL of purified water, and 6 mL of glacial acetic acid. The method was evaluated in accordance with ICH Q2 (R2) guidelines for validation parameters: selectivity, linearity (range 0.10-3.00 mg/mL), the limit of detection (LOD = 0.028 mg/mL), the limit of quantification (LOQ = 0.085 mg/mL), accuracy (confidence intervals < 0.05%), repeatability (peak area ratio = 0.39-1.97), and intermediate precision (peak area ratio = 0.40-1.98). The method is applicable for detecting and quantifying Camphor in a variety of cosmetic and pharmaceutical products from different parts of the world, thus covering the concentrations required by different law legislations. |
