Description of key information

Waiver:
The performance of a test for toxicity to soil microorganisms is scientifically unjustified.
REACh Regulation No. 1907/2006, Annex IX, Sect. 9.4, Col. 2, states as follows:
“9.4: Effects on terrestrial organisms: These studies do not need 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 organisms is scientifically unjustified.
