Description of key information

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

Additional information

The particle size distribution is not of interest as this dyestuff is handled during production only as a wet press cake and at downstream users as a preparation containing dispersing agents.

The substance is isolated together with dispersing agent by spray drying; the particle size is not a function of the chemical but a function of the spray dryer used; a typical particle size for disperse dyes isolated as low dust particles is about: 120 - 200 µm
