A simple high performance liquid chromatography (HPLC) method was developed for the assay of bemotrizinol (Tinosorb-S) from the complex pharmaceutical cosmetics matrix. Unlike the existing methods, the proposed mobile phase used in this method is very simple and excluding buffer. The use of buffer reducing column longevity and also a time-consuming process which increases the cost of analysis. To overcome all the referred problems, the present article was developed and validated as per International Council for Harmonization (ICH) guidelines. The reverse-phase chromatography was performed on Shimadzu model no. SPD-M10A VP with LC solution software, ?Bondapack (3.9 × 300 mm, 10-micron particle size) column with methanol (100%) as mobile phase at a flow rate 2.5 mL per minutes and UV detection at 254 nm. The retention time of bemotrizinol was found in 17.599 minutes, and the linear regression analysis data for the calibration plots showed a good linear relationship in the concentration range 70 to 130 ?g/mL. The value of the correlation coefficient, slope, and intercept were 0.996, 7,715, and 15,320, respectively. The limit of quantification (LoQ) and limit of detection (LoD) were found to be 1.32 and 0.44, respectively. The relative standard deviation (RSD) for intra-day sample A 1.0858, sample B 0.8859, and inter-day sample A 0.9921, sample B 0.967 which were found to be lesser than 2%. The developed method was validated with regard to linearity, accuracy, precision, selectivity, and robustness, and the method was found to be simple, cost-effective, precise, accurate, linear, and specific for the successful identification and determination of bemotrizinol in pharmaceutical cosmetic preparation.
