This survey clarifies that DTBHQ is listed for possible use in printing inks food contact materials, but that is not used by European producers and importers. The substance is not allowed for use in plastic materials for food contact. A potential use in water pipes was not confirmed. Overall, the report concludes that there is no information on actual use of DTBHQ in food contact materials in Denmark.
The project is following up on a previous survey under the Danish EPA’s LOUS-review (Environmental Project no. 1477).
