AB  - A new one-step sample preparation technique termed ultrasound-assisted 
      low-density solvent dispersive liquid-liquid extraction (UA-LDS-DLLE) coupled 
      with ion chromatography (IC) was developed for the determination of three 
      alkanolamines and two alkylamines in complex samples. Sample matrices were 
      rapidly dissolved and dispersed to form cloudy solutions by using two solvents, 
      where target analytes were transferred into acid solutions, while liposoluble 
      substances were dissolved in cyclohexane. The obtained extracts could be used 
      directly for injection analysis without any additional purification because the 
      potential matrix interferences had been effectively eliminated in extraction 
      process. The extraction efficiency could be markedly enhanced and the extraction 
      could be quickly accomplished within 13 min under the synergistic effects of 
      ultrasound radiation, vibration and heating. Various parameters influencing 
      extraction efficiency were evaluated using orthogonal array experimental design. 
      The extraction performance of the approach was demonstrated for the determination 
      of target analytes in 15 commercial cosmetics covering very different matrices. 
      Linearity ranges of 0.3-50 mg L(-1) and limits of detection varying from 0.072 to 
      0.12 mg L(-1) were achieved. The recoveries ranged from 86.9-108.5% with the 
      relative standard deviations (RSDs) of 1.2-6.2%. The method was proved to be a 
      simple and effective extraction technique that provided an attractive alternative 
      to the analysis of trace amounts of target analytes in large numbers of 
      cosmetics.
