The study combined migration tests using 10% ethanol, 3% acetic acid, and simulant E (Tenax\u00ae) with direct headspace (HS) analysis of the molds by gas chromatography\u2013mass spectrometry (GC-MS). HS analysis and migration tests with aqueous simulants were performed over three heating cycles to simulate repeated use. A non-targeted analytical approach was applied, followed by selective quantification based on toxicological criteria and the relevance of the compounds to the material. A total of 128 substances were identified, including siloxanes and non-intentionally added substances (NIASs). Siloxanes were detected in both simulant E and 10% ethanol. Most NIASs were found at levels below the limit of quantification or within regulatory limits, except for dibutyl phthalate, which exceeded its specific migration limit (0.3 mg kg\u22121). Furthermore, the sum of migrated cyclic siloxanes in simulant E surpassed the generic specific migration limit (60 mg kg\u22121) established in Spanish Royal Decree 847\/2011, while the release of volatile organic compounds exceeded the recommended value of 0.5%. The results revealed a complex chemical profile characterized by diverse NIASs and elevated migration of cyclic siloxanes in simulant E.<\/jats:p>","DOI":"10.3390\/polym18172162","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T16:07:32Z","timestamp":1788538052000},"page":"2162","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Chemical Characterization and Migration Profile of Silicone Molds for Air Fryers"],"prefix":"10.3390","volume":"18","author":[{"given":"Janira","family":"Ja\u00e9n","sequence":"first","affiliation":[{"name":"Analytical Chemistry Department, Universidad de Panam\u00e1, Sim\u00f3n Bolivar Avenue, P.O.
