Endpoint summary
Administrative data
Description of key information
The category is considered inherently biodegradable based on ready biodegradability tests and QSAR data (BIOWIN, BioHCwin). It is not technically feasible to perform simulation testing on ultimate degradation in sediment, surface water or soil on UVCBs. Current test procedures are not suitable for the characterisation of the degradation potential and potential metabolite formation of these substances due to their complex compositions.
Additional information
Three biodegradation studies are available for two streams in this category, all of which indicate that the streams cannot be considered readily biodegradable. The applicability of the available biodegradation methods for UVCB is not clear so these results may not be representative of the actual biodegradation of the streams. The proprietary study with DCPD/Codimer Concentrate (CAS No. 68478-10-4), which is GLP compliant and followed OECD guideline 301F, showed that DCPD/Codimer Concentrate cannot be considered readily biodegradable as there was no measurable biodegradation observed over a 28-day testing period. The two studies for the stream CAS No. 68477-54-3 are GLP compliant studies following OECD guideline 301F. The average biodegradation in one of the studies was 43.87% by day 56 and in the other study was 6.48% on day 41.
However, of the 119 measured constituents of this category (at equal or above 0.1% w/w), the majority of the constituents in the streams were found to have a half-life of <40 days and this is indicative of fast biodegrdation. In addition, and according to the criteria set out in the ECHA R.7b Information Requirements Guidance, 118 (BIOWIN 2), 101 (BIOWIN 3), 22 (BIOWIN 5) and 57 (BIOWIN 6) were predicted to be readily biodegradable based on the different models, with 119 constituents having at least one prediction of a high probability that it will biodegrade fast.
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).
