Safety assessment of the substance (triethanolamine-perchlorate, sodium salt) dimer, for use in food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the substance (triethanolamine-perchlorate, sodium salt) dimer, FCM substance No 1080, intended to be used as a thermal stabiliser at up to 0.15% w/w in rigid poly(vinyl chloride) (PVC) for repeated use bottles in contact with water. No thermal degradation of the substance is expected during the manufacture of the PVC articles. In water, the substance fully dissociates into triethanolamine, sodium (cations) and perchlorate. Therefore, migration would lead to exposure to triethanolamine and perchlorate and not to the substance itself. Specific migration of perchlorate, ethanolamine, diethanolamine and triethanolamine was tested under repeated use conditions covering the requested uses. After the second and third contacts, perchlorate was detected at ca. 0.3 μg/kg food. Ethanolamine, diethanolamine and triethanolamine were not detected in any of the three contacts at an estimated limit of detection of 0.03 mg/kg food. The available studies on the substance confirmed the lack of concern for genotoxicity, as anticipated by the dissociation of the substance into authorised non-genotoxic substances. Therefore, the CEP Panel concluded that the substance is not of safety concern for the consumer if used, under the condition requested by the applicant, as an additive at up to 0.15% w/w in rigid PVC for repeated use bottles intended for contact with water. Additionally, the migration of triethanolamine and perchlorate should not exceed the specific migration limits (SMLs) of 50 μg/kg food and 2 μg/kg food, respectively, set in the Regulation (EU) 10/2011. This evaluation also covers acidic foods such as fruit juices that can reasonably be foreseen to be in contact.
