AB  - A method has been developed for the determination of di (hydrogenated tallow 
      alkyl) dimethyl ammonium compounds (DHTDMAC) in textile auxiliaries by ultra-high 
      performance liquid chromatography-tandem mass spectrometry. (UPLC-MS/MS). The 
      samples were extracted and diluted with acidified methanol by 5% (v/v) formic 
      acid under ultrasonic assistance. The separation was performed on an Eclipse Plus 
      C18 column (50 mm x 2.1 mm, 1.8 microm) using 0.1% (v/v) formic acid solution and 
      methanol as the mobile phases. Identification and quantification were achieved by 
      UPLC-MS/MS with electrospray ionization (ESI) source in positive ion mode and 
      multiple reaction monitoring (MRM) mode. The results indicated that the 
      calibration curve of DHTDMAC showed good linear relationship between peak area 
      and mass concentration in the range of 10-280 microg/L with the correlation 
      coefficient (r2) of 0.9991. The limit of detection (LOD, S/N=3) and the limit of 
      quantification (LOQ, S/N= 10) of this method were 3 mg/kg and 10 mg/kg, 
      respectively. The average recoveries from three typical textile auxiliary 
      matrices including dispersant, antistatic agent and fabric softener, at three 
      spiked levels were in the range of 97.2%-108.3% with the relative standard 
      deviations (RSDs) of 1.5%-4.6%. The method is sensitive, accurate, simple and 
      effective for the analysis of DHTDMAC in textile auxiliaries.
