Description of key information

According to Annex VII, column 2, testing is not necessary. 

Additional information

The substance is never handled as powder; during production there is only a worker's exposure to a reaction solution or a wet press cake. The test item is finally spray dried to a microgranular powder. The worker's exposure in the dyeing process is only to a disperse dyestuff preparation containing a large amount of dispersing agents. Thus no exposure to the substance in a dry inhalable form.
