Article Synopsis
  • - This study focuses on creating and validating a new multivariate method to measure 24 potentially allergenic substances (PAS) linked to fragrances, using advanced techniques like ultrasound-assisted emulsification microextraction and HPLC-DAD.
  • - The method is an extension of an earlier univariate approach and has proven effective even in complex scenarios, successfully handling issues like overlapping spectra and baseline shifts, achieving high quality parameters (R≥0.94).
  • - Results show the new method provides reliable predictions and quantifications, with low prediction errors and good recovery rates in real samples, making it a promising tool for allergen analysis in fragrances.

A simple, inexpensive, and environmentally friendly method based on ultrasound-assisted emulsification microextraction followed by solidification of floating organic drop and high-performance liquid chromatography coupled to diode array detection was developed for the simultaneous determination of 18 potentially allergenic fragrance substances. Several parameters affecting the microextraction process were investigated in detail by the "one-variable-at-a-time" approach. Optimal conditions were the following: 50 μL of 2-dodecanol as extraction solvent, 10 mL of sample containing 150 g/L of salt, and 5 min of sonication at 35°C.
