Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 a test for toxicity to terrestrial plants is scientifically unjustified.
REACh Regulation No. 1907/2006, Annex IX, Sect. 9.4, Col. 2, states as follows:
“9.4: These studies need not to be conducted if direct and indirect exposure of the soil compartment is unlikely.”
Direct and indirect exposure of the soil compartment 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 soil compartment is practically negligible.
In summary, direct and indirect exposure o 4,4-sulphonyldiphenol to soil compartment, is unlikely and thus, performance of a test to terrestrial plants is scientifically unjustified.
