- Executive summary:
The particle size distribution of 3,9-Di-3-cyclohexen-1-yl-2,4,8,10-tetraoxaspiro [5.5]undecane was determined by scanning electron microscopy after the samples was fractionated by a 100 μm sieve. The test material tested according to OECD Guidelines for Testing of Chemicals No: 110 method B “Particle Size Distribution/Fibre Length and diameter Distributions” was found to have a mass median aerodynamic diameter of 25.50 µm.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
