Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

The study is considered not scientifically justified.
Executive summary:

The registered substance is produced, supplied and marketed in the presence of a liquid mineral oil solvent. Removal of this solvent is expected to cause a change in the equilibrium of the chemical structure of the alkaryl benzene sulfonates 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.

From the compositional description, the structural formula given, and considering that the substance is used at extremely high temeratures (typically upto 300C) with no change in stability, it can be concluded that it is not necessary to evaluate the ignition temperature of this substance by either the Self- or Auto-Ignition testing criteria indicated in the TGD. There are no functional groups or other structural alerts present that indicate that this substance would spontaneously ignite in air when exposed to a hot surface and thus should not be classified as dangerous with respect to this endpoint. This empirical evaluation is furthermore confirmed by long term handling experience. The study is therefore considered scientifically unjustified.
