Risk assessment

In 2014, diundecyl phthalate was included in the EU's ongoing action plan ( CoRAP ) in accordance with Regulation (EC) No. 1907/2006 (REACH) as part of substance evaluation . The effects of the substance on human health and the environment are re-evaluated and, if necessary, follow-up measures are initiated. The reasons for the uptake of diundecyl phthalate were concerns about high (aggregated) tonnage and the dangers arising from a possible assignment to the group of CMR substances. The re-evaluation has been running since 2014 and is carried out by Denmark .
