Description of key information

Additional information

The registered substance is produced, supplied and marketed in the presence of a liquid sodium sulphate mineral oil solvent. Removal of this solvent is expected to cause a change in the equilibrium of the chemical structure of the benzene sulfonic acid and the associated salts resulting in a degradation of the chemical structure to a structure that is not representive of the substance being placed on the market in the EU. It is, in consequence, not possible to undertake any study of the registered substance in the absence of the solvent. This is further compounded by the fact that the presence of the sodium sulphate solvent changes the physical state of the registered substance from solid to liquid and will therefore have a considerable effect on the result of any test conducted on the substance in solvent. It is therefore considered justifiable to omit any study.

The substance has, based on QSAR, an extremely low water solubility well below 0.1mg/l, which is consistent with expectation based upon chemical structure. The substance therefore meets the criteria for data waiving.
