Description of key information

The mean particle size of the test substance is 70 microns as determined by Horiba LA920 light scattering.  However, optical microscopy shows that the test substance contains particles that are acicular to rectangular in shape which is not an ideal shape for light scattering.  Optical microscopy shows that the maximum longest diameter ranges up to 200 um and the maximum shortest diameter ranges up to 75 um.
