Paper spray tandem mass spectrometry: A rapid approach for the assay of parabens in cosmetics and drugs

Abstract

A fast methodology for the assay of parabens in drug and cosmetic preparations has been presented. The procedure developed is based on paper spray tandem mass spectrometry and isotope dilution approach. For each investigated paraben, the corresponding labeled standard has been used in order to improve the accuracy and reproducibility of the analyses. The MS experiments have been performed under MRM conditions, monitoring the transitions [M‐H]− → m/z 92 and [M‐H]− → m/z 98, respectively, for each analyte and the corresponding labeled internal standard. The quantitative assay has been performed using a calibration curve built from 2 to 15 mg/L. The method accuracy, in all case near 100%, was evaluated using fortified samples at two concentration levels, which are representative of the lower and the higher portion of calibration curve. The good values of LOQ, LOD, and reproducibility confirm the consistency of the developed approach.

“…Although parabens are added to goods due to their antimicrobial properties, they are also weak endocrine disrupters, thus their presence in certain products must be regulated. Bartella et al used PSI‐MS for the rapid analysis of parabens in consumer products 139 . Various commercially available products were analyzed, including makeup cream, anti‐aging cream, toothpaste, and cough syrup.…”

“…Bartella et al used PSI‐MS for the rapid analysis of parabens in consumer products. 139 Various commercially available products were analyzed, including makeup cream, anti‐aging cream, toothpaste, and cough syrup. The study described a rapid and reliable technique for the detection of parabens in a range of matrices, with RSD values lower than 15%.…”
