Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

In biodegradation tests (ECB, 2000; Scholz et al., 1996; Chang et al., 2005; Ziogou et al., 1981; Howard et al., 1984) clearly, the 10 day window has been reached, and DBP can be considered as readily biodegradable.

DBP is biodegradable in natural waters and sediments, with an estimated half-life in the range of 1 to 17 days (Johnson and Lulves, 1975; Johnson et al, 1984; Walker, 1984; Shelton et al., 1984).

Study for biodegradation in soil according to column 2 ANNEX IX of REACH Regulation (EC) No 1907/2006 not need to be conducted if the substance is readily biodegradable and DBP is readily biodegradable. Chang et al. 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.
