Additional information

According to column 2 ANNEX IX of REACH Regulation (EC) No 1907/2006, the study need not be conducted if the substance is readily biodegradable and DBP is readily biodegradable.

Chang et al., 2009 studied the biodegradation of DEHP and DBP in two types of compost or in compost amended soil. This study was not enough detailed and performed under controlled parameter (no field study) and on Asiatic soil and compost. Therefore, this study is considered as not assignable. It however gives indication that DBP is biodegradable in soil with short half- life consistent with other studies performed in aquatic test condition.
