摘要
Gas chromatography-mass spectrometry (GC-MS) method has been developed for the simultaneous determination of monoethanolamine,diethanolamine,triethanolamine in cosmetics.The detected materials were extracted with ethanol by ultrasonic, then were analyzed by GC-FID and GC-MSD.The relative standard deviations (RSD) were 0.76%-3.43%,and recoveries were 85.8%-106.0%. The limit of detection was 0.05%.
