Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
"Not rapidly degradable" applies as the substance is biodegraded in a test for ready biodegradability to 54 % within 28 days. Although, there are papers available that for such an UVCB-substance, and also for closely related substances such as Rosin, other criteria should be applied because the degradation of the single substances included in the UVCB substance are degraded one after the other under the strict conditions of the ready biodegradability tests and therefore need more time for degradation (expressed by the 54 % for Resin 835A just not reaching the threshold of 60 %) compared to environmental conditions or even more to conditions in a sewage treatment plant.
The substance is inherently degradable. 54 % are biodegraded (to CO2) within 28 d in a test for ready biodegradability under its strict conditions, so that it can be assumed that Resin 835A is completely mineralized in a WWTP by adapted microorganisms and only a negligible concentration is expected in the effluent and thereby in the receiving river.
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.
