Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a study on ready biodegradability of 1,7 -octadiene, the substance attained 53% degradation within 28 days of incubation. Hence, 1,7-octadiene has to be classified as not readily biodegradable according to the strict OECD criteria. Nevertheless, to further evaluate the biodegradation potential of the substance, a QSAR calculation using BIOWIN v. 4.00 is performed. On the basis of this calculation the ready biodegradability of the test substance is assumed.
According to ECHA Guideline R7b, "“Biodegradation above 20% of theoretical (measured as BOD, DOC removal or COD) may be regarded as evidence of inherent, primary biodegradability, whereas biodegradation above 70% of theoretical (measured as BOD, DOC removal or COD) may be regarded as evidence of inherent, ultimate biodegradability. ”
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
