Abstract:

A high performance liquid chromatography (HPLC) method for the determination of tranexamic acid in whitening cosmetics was established. The tranexamic acid in cosmetic samples was extracted directly with 5% methanol solution. The separation was performed on a Shiseido CAPCELL PAK C18 UG120 column (4.6 mm×250 mm×5 μm), with the mobile phase of methanol and 0.05 mol/L KH2PO4-0.2% H3PO4 solution. The flow rate was 1.0 mL/min and detection wavelength was 210 nm. The detection results show good linearity within the range of 5-100 mg/L (r>0.999). The limit of detection (LOD) is 10.7-22.2 μg/g and the limit of quantitation (LOQ) is 28.9-48.0 μg/g in the cosmetics matrix. The recoveries range from 95.23% to 110.40%, and the RSD range is 1.24%-3.59%(n=6). The intraday stability is good, and the peak area RSD value is 0.026% within 24 h. The method is simple and reliable, and can be used for the determination of tranexamic acid in whitening cosmetics.
