AB  - An indirect ultraviolet detection method for simultaneous analysis of five 
      organic acids by capillary electrophoresis was established. The concentration of 
      the tetradecyltrimethylammonium bromide (TTAB) surfactant in the background 
      electrolyte solution and the pH of the solution were optimized. Five organic 
      acids formic acid, malic acid, citric acid, glycolic acid, lactic acid were 
      effectively separated from each other within 6 min with an electrolyte solution 
      (15 mmol/L potassium hydrogen phthalate and 0.4 mmol/L TTAB, pH 5.6) under 
      conditions of -15 kV, 25℃, and 254 nm, while the injection pressure was 5 kPa and 
      the injection time was 5 s. The linear ranges were 15-600 mg/L, 30-800 mg/L, 
      20-700 mg/L, 40-500 mg/L, and 30-5000 mg/Lfor formic acid, malic acid, citric 
      acid, glycolic acid, and lactic acid, respectively, with correlation coefficients 
      of 0.9983-0.9998. The detection limits were between 0.1 mug/g and 2.0 mug/g. The 
      method can be used for the detection of five organic acids in three types of 
      cosmetics including aqueous, lotion and cream. At three spiked levels, the 
      recoveries of organic acids were between 95.0% and 101.6%, and relative standard 
      deviations (RSDs) were within 2.0%. The proposed method is easy, rapid, 
      environment friendly, and sensitive with good reproducibility. It can be used for 
      the monitoring of five organic acids in the production and storage of cosmetics 
      including aqueous, lotion and cream.
