Additional information

According to REACH Annex IX Column 2 (9.2.1.3.), the study need not to be conducted if the substance is readily biodegradable. The substance is predicted to be readily biodegradable.

The predicted degradation half-lives in soil for constituents of this substance range between 4.03 and 225 days. 

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).
