Applicant's summary and conclusion

Conclusions:
1,1'-azobis(1-cyclohexanecarbonitrile) is described as a crystalline solid. Furthermore the substance does not fulfill the criteria for gases or liquids according to Annex I, Part 1, 1.0 definitions of CLP Regulation, and therefore is considered as solid substance at room temperature.
