SCCS Opinion on Copper (nano) and Colloidal Copper (nano) - Final Opinion
Résumé
In total, 9 manufacturers notified the European Commission about 36 different products containing nanosized copper (nanoCu). For every copper dispersion, four different files were presented: a notification file, a safety file, a specification file and a file on the toxicity profile. After initial evaluation and a request for additional information, two manufacturers withdrew their products (n=7) from the notification. Therefore, these 7 products were excluded from evaluation, resulting in the final evaluation of 29 nanosized copper products produced by 7 manufacturers. For three different copper nanomaterials, notification files were provided. These were Copper Water nano-Tech 100 ppm, Copper Water nano-Tech 50 ppm, and ECO COPPER NANO-COLOID. For all three copper nanomaterials, the notified files were insufficient regarding their characterisation and for conducting a safety evaluation. All copper nanomaterials claimed to have an antimicrobial activity. Most files contained declarations of safety without any supporting data or documentation. Based on the provided information, it is not possible to perform a safety assessment on these copper nanomaterials.
