Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACH Annex XI, the hydrolysis study does not need to be conducted as this substance is not expected to undergo hydrolysis in the environment due to a lack of hydrolysable functional groups and therefore testing does not appear scientifically necessary. In addition, data on Sulfolane (CAS 126-33-0, EC 204-783-1), indicated that sulfolane is not hydrolysable (see ECHA registration dossier). The half-life of Sulfolane is >5 days at 50 ºC, pH 4, 7, and 9 (OECD 111) (equivalent to a half-life > one year at room temperature) and Sulfolane is considered to be stable to hydrolysis under environmental conditions (MITI Japan, 2001). (Source: SIDS dossier Sulfolane). Sulfolane and 3-methyl sulfolane differ from each other in a methyl group. It is therefore not expected that because of the methyl group present in 3-methyl sulfolane this substance will undergo hydrolysis under environmental conditions.

Applicant's summary and conclusion
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.
