Applicant's summary and conclusion

Conclusions:
The study is considered to be technically not feasible
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. Given that this substance will never be placed on the market in the EU, used or supplied in a solid form it is considered justifiable to omit any study for the particle size distribution as any result would not be representative of the registered substance nor assist in the assessment of any hazard pertaining to the substance during use and potential exposure in the EU.
