Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
A test on ready biodegradability was conducted comparable to OECD Guideline 301 B (CO2 -Evolution Test). After 32 days, IPPD showed 18.9 % degradation. Therefore IPPD is not readily biodegradable (Monsanto, 1979).
Environmental fate screening (river-die-away-test) of IPPD for biological and chemical transformations was carried out in Mississippi River water (active and sterile) and purified water at an initial concentration of 1000 µg/L. Half-lives for IPPD ranged from 2 to 11 hours (Monsanto, 1981). These results only reflect the primary degradation of the substance. However, degradation in natural Mississippi water was significantly enhanced compared to sterile waters indicating that trace elements and biodegradation may play a role.
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.
