Objective: The objective of this study was to optimize high-performance liquid chromatography (HPLC) method for the determination of acid orange 7 (AO7) and sudan II (SII) in blusher product based on response surface methodology using box behnken design (BBD) approach. Methods: Some factors responsible for HPLC separation including column temperature, mobile phase composition, flow rate were optimized using BBD. The responses evaluated were peak area, retention time, and tailing factor. AO7 and SII in blusher product has different properties, therefore both analytes were analysed using C18 column (Thermo Synergy Gold 250 mm x 4.6 mm i.d.,5 µm) using Shimadzu LC 20AD chromatograph equipped with photo-diode array (PDA) detector at 300-650 nm. The mobile phase used was acetonitrile-water (1:1 v/v), and acetonitrile composition was optimized at 35-50% for separation AO7 (ACN1), and 80-90% for SII (ACN2), delivered at the flow rate of 0.9–1 ml/min, using column temperature at 30-40 °C. Results: BBD showed that separation of AO7 was influenced by the concentration of ACN1, flow rate and column temperature. These factors affected retention time, peak area, and tailing factor with peak area was the most significant. Tailing factor was not significantly affected by each factor, and retention time was slightly effected. Otherwise, Sudan II was affected by all these factors except ACN1. The optimal condition obtained based BBD was ACN1 43%, ACN2 90%, the flow rate of 0.9 ml/min and a column temperature of 40 °C. Conclusion: BBD can be used to get optimum condition for analysis of AO7 and SII in blusher product.
