Conclusions:
According to OECD 110, the mean particle size distribution of Everzol Red CDN Crude was determined to be 49.526 μm.
Executive summary:

This test using the procedures outlined in the SNCL Study Plan for IA09-06 and OECD 110. About 55 mg of the test substance was homogenized with 100 mL ethanol in beaker. Determination of particle size distribution by particle size analyzer. Therefore, Everzol Red CDN Crude presents the average value of particle size distribution to be 49.526 μm.
