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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
DIUP is expected to have a half-life in soil similar to DINP, approximately 51 days.
Key value for chemical safety assessment
Additional information
Studies are not available to assess the biodegradability of DIUP specifically in soil. However, data for an analog substance di-isononyl phthalate (DINP) can be used to estimate the loss rate of DIUP in soil. DINP exhibited a half-life in soil of approximately 51 days, based on the loss of parent substance (ExxonMobil, 2009b). These data were developed in an earthworm toxicity test conducted in soil in which the concentration of DINP was monitored over a 56-day period. During that period DINP concentration decreased from 982 to 441 mg/kg soil (wet weight). Because DIUP and DINP exhibited similar extents of biodegradation in ready biodegradability tests, they would be expected to biodegrade in soil at similar rates and to similar extents.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
