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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Not relevant due to ready biodegradation
Key value for chemical safety assessment
Additional information
Experimental studies investigating the abiotic hydrolysis of Glycerides, tall-oil mono-, di-, and tri- (CAS 97722-02-6) are not available. However, in accordance with Annex VIII, column 2, 9.2.2.1. of Regulation (EC) 1907/2006, testing is not required since the substance is readily biodegradable. The results from the supporting QSAR calculation with HYDROWIN v2.00 indicate that hydrolysis is not relevant for the substance, since the estimated half-lives of the main components range from 1.5 to 10.3 years at pH 7. Half-lives of 55.1 days to one year were calculated for hydrolysis at pH 8 (Gebhardt, 2013).
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.
