“…PP resulted to be the most used plastic as an alternative to PC baby bottles on the Belgian market, representing more than 60% of the market share. Previous studies already demonstrated that a wide variety of chemicals present in PP plastics could migrate towards the food (Mcdonald et al 2008;Alin and Hakkarainen 2010;Chang et al 2016). For baby bottles, severe differences in the identity and the concentration of the compounds migrating from the different PP bottles were observed (Simoneau et al 2012;Onghena et al 2014) which agreed with the data obtained in this study.…”

Following the recent prohibition on the use of BPA for the production of polycarbonate (PC) baby bottles in the European Union, baby bottles made of alternative materials, such as polypropylene, polyethersulphone, polyamide, Tritan™ or silicone, have appeared on the market. An initial study done in previous work applying a liquid-liquid extraction (LLE) followed by GC-MS analysis identified a wide variety of migrating compounds. Based on these screening results, the monitoring and quantification of the most important migrating compounds was further pursued. We describe the optimisation, validation and application of a LLE extraction method for the extraction of these migrating compounds adapted to low concentrations. Generally, absolute recoveries between 70 and 110% with RSDs < 20% were obtained. Further, specific and quantitative GC-QqQ-MS and LC-QqQ-MS methods were developed and validated by evaluating the following parameters: sensitivity, selectivity, linearity, accuracy, precision, recoveries and matrix effects. Limits of quantification (LOQ) ranged between 0.6 and 8 µg kg -1 for the majority of the selected compounds. Linearity ranged using the Mandel's fitting test between coefficients of determination (R²) of 0.995 and 0.999. Both repeatability and reproducibility were demonstrated to be satisfactory considering the Horwitz equation. Finally, the methods were applied on a selection of baby bottles representative for the Belgian market. Several compounds previously identified by the screening approach were confirmed and adequately quantified. For instance, azacyclotridecan-2-one had a maximum migration value of 1091 µg kg -1 ; whereas 4propylbenzaldehyde migrated at 27 µg kg -1 and 2,2,4-trimethyl-1,3-pentanediol diisobutyrate (TXIB) at 348 µg kg -1 . However, most of the targeted compounds were not detected or below the LOQ.

“…Migration to dry food simulant E (Tenax) was well below the EU limit. In previous studies, it was also reported that water and ethanol were good solvents for PU network and caused swelling in polymer . Swelling alters the structure and morphology of the polymer network, increasing the activity of the molecular chains and the internal free volume .…”

A thermoplastic polyurethane (PU) polymer was synthesized, casted into films, and specific and overall migration (OM) tests were applied. A new method with gas chromatography-flame ionization detector was proposed to measure specific migration (SM) of 1,4-butanediol from the PU film. OM values in the four established simulants were under the legal limits. Determination of 1,4-butanediol migrating from PU film to the three established simulants showed maximum SM result as 1.5 mg/kg which was far below the legal limits. Therefore, the PU film has a good potential as a safe food contact material. Moreover, the analytical method used for determination of SM of 1,4-butanediol resulted in good analytical characteristics and detection limits at ppm level.
