Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Adsorption coefficient
Type:
log Koc
Value:
>= 2.5 - <= 3.16 dimensionless
pH:
7
Temp.:
20 °C
Remarks on result:
other: See Remarks
Remarks:
Multiple results Calculated log Koc for constituents of this substance range between 2.48 - 3.16. It should be borne in mind that this is the full range of predicted values, and that this may be misleading or unrepresentative of the properties of the UVCB substance as a whole. The range sh ould therefore be treated with caution and not taken out of context. The substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is characterised using quantitative structure p roperty relationships for representative hydrocarbon structures that comprise the hydrocarbon block s used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK spreadsheet attached in IUCLID section 13).
