Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
No test data for hydrolysis or photodegradation are currently available
Biodegradation
The reference substance BisP-IOTD was investigated for ready biodegradability in a closed bottle test according to OECD method 301D. The relative biodegradation values calculated from the O2 measurements performed during the test period of 28 days revealed no signficant biodegradation of BisP-IOTD at both concentrations tested (1 mg/l and 3 mg/l) and thus BisP-IOTD is designated as not readily biodegradable. No further studies on biodegradation are available and not required at the tonnage band of 1 - 10 T/a.
Bioaccumulation
The substance BisP-IOTD has a moderate to low potential for bioaccumulation as shown by the result of logPOW determination (log POW = 3.8). A study to assess bioconcentration is not available and not required at this tonnage band (1 - 10 T/a).
Transport and Distribution
No data on adsorption/desorption to organic matter is available at this tonnage band. However, applying the methodology of Sablijic and Güsten (1995) tailored to phenols, a KOC-value of 1762 can be estimated form the experimentally derived logPOW of 3.8. Thus, the substance is expected to adsorb to organic matter having limited mobility in soil.
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.
