Quantification of the Synthetic Phenolic Antioxidant Cyanox 1790 in Bottled Water with SPE-HPLC/MS/MS and Determination of the Impact of the Use of Recycled Packaging on Its Generation

One route of exposure to SPAs is through bottled water since the polymers used make plastic bottles contain these SPAs, which migrate from water. Solid-phase extraction (SPE), HPLC-MS, FTIR, and DSC are identify quantify in Interday measurements cyanox 1790 with HPLC showed RSD, error, R2 lower than 3.78, 9.3, 0.99995, respectively. For intraday water, were less 4.1, 11.2, Concentrations Cyanox non-recycled ranged 0.01 ± 0.0004 4.15 0. 14 ppm, while levels recycled between 0.0005 11.27 0.12 ppm. In tests carried out, an increase migration was identified, ppm increased as days storage at 40 °C.
