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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation in air
Estimated half-lives for the components of this UVCB substance range from 1.2 to 2.6 hours.
Hydrolysis
Ether bonds are stable and do not hydrolyse to a significant extent at environmental relevant condition. This has been confirmed in an OECD 111 study with a structural analogue, Propylidinetrimethanol, ethoxylated (CAS# 50586-59-9). This substance was stable at pH 4, 7, 9 at 50 degrees Celsius during 120 hours (Bayer Material Science, AG, 2009).
Biodegradation
Inherently biodegradable (49% after 28 days in a manometric test).
Bioaccumulation
With a log Kow ≤3, the substance can be considered to have a low potential for bioaccumulation.
Adsorption/desorption
In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted as the substance can be expected to have a low potential for sorption (log Kow ≤3). The estimated Koc value for homologous components of this UVCB substance was 10 L/kg for the full range of homologues (low - high molecular weight). The components of this UVCB substance can be regarded as having low affinity for adsorption to soils and activated sludge biosolids.
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.
