Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Study not feasible due to presence of mineral oil solvent, therefore a data waiver has been proposed for this endpoint.

Key value for chemical safety assessment

Additional information

The registered substance is produced, supplied and marketed in the presence of mineral oil solvent. Removal of this solvent is expected to cause a change in the equilibrium of the chemical structure of the benzenesulfonic acid and the associated salts resulting in a degradation of the chemical structure to a structure that is not representative 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 mineral oil 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.

In addition, the substance has low water solubility, which is consistent with expectation based upon chemical structure. Therefore, the substance meets the criteria for data waiving.
