The filter membranes are used to process aqueous and alcoholic foods, for up to 24 h per day up to \u25a0\u25a0\u25a0\u25a0\u25a0 at temperatures up to 35\u00b0C. The substance is a polymer with \u2264 \u25a0\u25a0\u25a0\u25a0\u25a0% w\/w low molecular weight fraction (LMWF, &lt;\u20091000 Da). Migration tests simulated the actual use conditions by repeatedly flushing \u25a0\u25a0\u25a0\u25a0\u25a0\u2010based filter membranes with the food simulant 20% ethanol in consecutive contact steps. The specific migration of the sum of the LMW oligomers was below 50 \u03bcg\/kg food. The specific migration of the monomer and of some impurities was not detected at the respective limits of detection (\u2264\u20094 \u03bcg\/kg food). The specific migration of the remaining impurities was not measured but calculated and was generally below 0.15 \u03bcg\/kg food. Genotoxicity studies on 2\u2010hydroxy\u2010N\u2010(hydroxyethyl)propanamide, which is structurally related to the LMW oligomers, demonstrated that the LMW oligomers do not raise a concern for genotoxicity. The in silico assessment of the impurities did not show the presence of structural alerts for genotoxicity. The Panel concluded that the substance is not of safety concern for the consumers if (i) it is used in repeated use \u25a0\u25a0\u25a0\u25a0\u25a0\u2010based filter membranes at temperatures up to 35\u00b0C for the processing of foodstuffs for which simulants A, B, C are laid down in Regulation (EU) 10\/2011, except human milk, liquid infant formula and water that could be used to reconstitute infant formula; and (ii) its content in the filter membrane does not exceed 40.7% w\/w, calculated based on the levels of the substance and \u25a0\u25a0\u25a0\u25a0\u25a0 in the initial wet membrane solution and considering a residual level of other components of 2% w\/w.<\/jats:p>","DOI":"10.2903\/j.efsa.2026.9932","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T13:04:40Z","timestamp":1773061480000},"source":"Crossref","is-referenced-by-count":0,"title":["Safety assessment of poly(2\u2010ethyl\u20102\u2010oxazoline) for use in food contact materials"],"prefix":"10.2903","volume":"24","author":[{"name":"EFSA Panel on Food Contact Materials (FCM)","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claude","family":"Lambr\u00e9","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riccardo","family":"Crebelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Joao","family":"da Silva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konrad","family":"Grob","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evgenia","family":"Lampi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Rosaria","family":"Milana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marja","family":"Pronk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"\u0160\u010detar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgios","family":"Theodoridis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Els","family":"Van Hoeck","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadia","family":"Waegeneers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronan","family":"Cariou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurence","family":"Castle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emma","family":"Di Consiglio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roland","family":"Franz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Barth\u00e9l\u00e9my","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniele","family":"Comandella","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gilles","family":"Rivi\u00e8re","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"10.2903\/j.efsa.2026.9932_ref1","doi-asserted-by":"crossref","unstructured":"Aljallal, M.
