Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Waiver:
The performance of long-term toxicity testing to sediment dwellers is scientifically unjustified.
REACh Regulation No. 1907/2006, Annex IX, Sect. 9.2.1.4, Col. 2, states as follows:
“9.2.1.4: The study need not to be conducted:
- if the substance is readily biodegradable, or
- if direct and indirect exposure of sediment is unlikely.”
Direct and indirect exposure of sediment is highly unlikely, as: 4,4-sulphonyldiphenol is manufactured and used in completely closed systems. Furthermore, 4,4-sulphonyldiphenol is not coming into contact with final consumers, because substance is chemical bounding completely during industrial polymerisation process.
Therefore, the direct and indirect release of 4,4-sulphonyldiphenol into sediment is practically negligible.
In summary, direct and indirect exposure of soil compartment to 4,4-sulphonyldiphenol is unlikely and thus, toxicity testing on sediment dwellers is scientifically unjustified.
Key value for chemical safety assessment
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.
