In this study, a rapid and sensitive analytical method for the determination of methyl-, ethyl-, propyl-, and butyl esters of para-hydroxy benzoic acid (parabens) in personal care products was developed and fully validated. Test portions were extracted with methanol followed by vortexing, sonication, centrifugation, and filtration without derivatization. The four parabens were quantified by GC-MS/MS in the electron ionization mode. Four corresponding isotopically labeled parabens were selected as internal standards, which were added at the beginning of the sample preparation and used to correct for recovery and matrix effects. Sensitivity, extraction efficiency, and recovery of the respective analytes were evaluated. The coefficients of determination (r(2)) were all greater than 0.995 for the four parabens investigated. The recoveries ranged from 97 to 107% at three spiked levels and a one-time (single) extraction efficiency greater than 97% was obtained. This method has been applied to screen 26 personal care products. This is the first time that a unique GC-MS/MS method with dynamic selected reaction monitoring and confirmation of analytes has been used to determine these parabens in cosmetic personal care products.

“…Table 4 compares some figures of merit generated by the proposed method and the published methods for analysis of parabens from various samples. Results show that analytical features of the proposed method are comparable or better than the other methods reported for extraction and determination of the parabens [12][13][14][15][16][17][18][19][20][21][22][23][24].…”

A SBA-15/polyaniline para-toluenesulfonic acid nanocomposite supported micro-solid-phase extraction procedure has been developed for the extraction of parabens (methylparaben, ethylparaben, and propylparaben) from wastewater and cosmetic products. The variables of interest in the extraction process were pH of sample, sample and eluent volumes, sorbent amount, salting-out effect, extraction and desorption time, and stirring rate. A Plackett-Burman design was performed for the screening of variables in order to determine the significant variables affecting the extraction efficiency. Then, the significant factors were optimized by using a central composite design. The optimum experimental conditions found at 50 mL sample solution, extraction and desorption times of 40 and 20 min, respectively, 500 μL of 3% v/v acetic acid in methanol as eluent, 0.01 M salt addition, and 10 mg of the sorbent. Under the optimum conditions, the developed method provided detection limits in the range of 0.08-0.4 ng/mL with good repeatability (RSD% < 7) and linearity (r(2) = 0.997-0.999) for the three parabens. Finally, this fast and efficient method was employed for the determination of target analytes in cosmetic products and wastewater, and satisfactory results were obtained.

ResumoOs polímeros de impressão molecular são materiais sintéticos dotados de sítios específicos de reconhecimento. Esses materiais são obtidos por reações de polimerização que fixam, estrategicamente, monômeros funcionais ao redor de uma molécula modelo de acordo com os grupos ligantes e com a estereoquímica de ambas as moléculas. Os MIPs têm sido amplamente empregados em procedimentos de preparo de amostras, como extração e microextração em fase sólida, extração sortiva em barra de agitação, extração com adsorvente magnético, microextração com sorvente empacotado, entre outras. Este artigo de revisão tem como objetivo apresentar o que há de mais recente no emprego de MIP para extração de compostos orgânicos, evidenciando as vantagens de cada aplicação, bem como as mais promissoras tendências que sustentam a evolução e o aperfeiçoamento de cada técnica. Palavras-chavePolímeros de impressão molecular; MIP; preparo de amostras.Molecularly imprinted polymers in sample preparation for organic compounds analysis: applications and trends AbstractMolecularly imprinted polymers are synthetic materials with molecular recognition ability. These materials are obtained by polymerization reactions that fix the functional monomers around the template molecule according with the binding groups and the stereochemistry of both molecules. The MIPs have been extensively used in several applications with emphasis for sample preparation procedures as solid phase extraction, solid phase microextraction, extraction by magnetic sorbents, microextraction by packed sorbent among others. So, the objective of this review is to present the novelty in MIP use for organic compounds extraction and point out the advantages of each application, as well as what is most promising in the evolution and improvement of each technique.
