Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
As the rapid hydrolysis is the driving force for the fate and pathways of this substance, the abiotic degradation can be used to demonstrate fast degradation for this substance. This is justified as all decomposition products have been identified (key study on hydrolysis including Tier 3 approach, Brekelmans M.J.C. 2013). The most relevant degradation product (2-ethylhexanol) is readily biodegradable (> 79 % to 100 % in 14-d MITI-I test; NITE 2002). Biooxidation studies of 2-ethylhexanol in freshwater as well as in synthetic seawater indicate biodegradability of > 86% in 20 days (Price et al 1974). Both degradation products are not classified as hazardous to the environment. The other environmentally non-hazardous degradation product (TiO2) is inorganic and insoluble, lacking bioavailability, and therefore not relevant to be considered in CSA.
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.
