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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The predicted log Koc of representative constituents of this category with KOCWIN range from 0.6 to 2.79. It is not feasible to perform simulation tests on complex, volatile UVCB.
Key value for chemical safety assessment
Additional information
Log additional adsorption / desorption values of 1,3-butadiene for sediment, suspended matter and soil of 2.58, 5.16 and 1.03 L/kg respectively are reported in the EU RAR (2002).
The log Koc of representative constituents of this category has been predicted using the EPISUITE v4.11 KOCWIN (2017) program, which uses methodology described by Sahljic et al., (1995) and Meylan et al. (1995). The predicted log Koc for this category is 0.6 to 2.79.
