Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with REACH Annex VIII column 2, hydrolysis study does not need to be conducted because the registered substance,(-)-(3aR,5aS,9aS,9bR)-3a,6,6,9a-Tetramethyldodecahydronaphtho[2,1-b]furan,is readily biodegradable. In addition, the registered substance contains no organic functional groups that may hydrolyse under environmental condition like alkyl halides, amides, amines, epoxides, esters. This substance consists only of organic functional groups that are relatively or completely inert with respect of hydrolysis. Based on the chemical structure an estimation of the hydrolysis rate is not possible.
This statement is supported by one study on the registered substance, not performed according to international guideline and not GLP. In this study, the disappearance of the registered substance after 5 days as well as after 28 days is less than 10% at any pH (from 2 to 12) at 40°C. Therefore, it can be concluded that the substance is hydrolytically stable under the conditions of the test. The test item is, therefore, assumed to be hydrolytically stable under the study conditions of the OECD 111 test guideline at pH 4, 7 and 9.
Additional information
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.
