Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

According to REACH Annex IX Column 2 (, simulation testing on ultimate degradation in surface water need not to be conducted if the substance is highly insoluble in water or readily biodegradable. The substance is readily biodegradable with water solubility less than 1 mg/L.

According to REACH Annex IX Column 2 (, sediment simulation testing need not to be conducted if the substance is readily biodegradable.

The substance is readily biodegradable.

The predicted degradation half-lives in surface water and sediment for constituents of this substance range between 4.03 and 225 days and 16.13 and 899 days, respectively.

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 should 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 property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK report attached in IUCLID section 13).
