Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic biodegradation data showed 18.9 % biodegradation. Therefore IPPD is not readily biodegradable and it is concluded that biodegradation in the terrestrial compartment will not occur to a relevant extent. Furthermore, the distribution modelling shows that the substance is to a high degree transported to the aqueous environment (about 88%) whereas only about 4% are expected in soil. The biodegradability in water  is limited but abiotic degradation by hydrolysis is the main degradation pathway. Thus, as soil also consists of pore water, hydrolysis is also expected in soil. Adsorption to soil particles might also play a role. However, the Koc of 246.8 indicates only a moderate potential for adsorption. For this reason hydrolysis is considered as the main relevant degradation pathway of the substance in soil.
