Description of key information

The approximate median particle sizes L50, L90, and L10 of dicumyl peroxide are 1700, 900, and 6200 µm, respectively. These data indicate that the fraction of particles of a size less than 100 µm is insignificant (only 0.25 % < 500 µm), demonstrating that a significant amount of inhalable particles need not be expected.

Additional information

Test was performed according to OECD guideline 110 ("Particle Size Distribution/Fibre Length and Diameter Distributions") and CIPAC MT 59: Sieve analysis.
