Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The test item showed to be readily biodegradable under the conditions applied in a Manometric Respirometry test, having reached the pass level (60% biodegradation) at the end of the 28 days test, showing a total 78.3% during the test period (mean values between two replicates).
Being an UVCB substance, following Regulation 286/2011 (emending the regulation 1272/2008 for the purposes of its adaptation to technical and scientific progress), point 4.1.2.9.5 part c, the 10-day window condition can be waived and the pass level applied at 28 days.
Moreover, the test item showed no inhibitory effects on the microorganism activity at the tested concentration, as demonstrated by the 25% of biodegradation exceeded in the toxicity control at the third day of test period.
The substance was also tested in its representative components, evaluated as conservative based on QSARs estimation on hypothetical structures: the non emulsifying fraction of the substance and the C14-17 chloroparaffins. In both cases the 10 day windows was respected and the pass level of 60 % was reached in 28 days. A third confirmatory Manometric Respirometry test has been also performed on the emulsifying fraction, showing ready bioderadability
As a conclusion, it can be assumed that the substance is readily biodegradable
Biodegradation on soil and sediment has been waived based on exposure considerations and the ready biodegradability of the substance
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).
