Description of key information

The mean particle size, number in volume, of DPG (1,3-diphenylguanidine) test item, is determined to be 26 µm, with 10% of particles presenting a diameter less than 10µm, and 10% of particles presenting a diameter larger than 45µm.

Additional information

A study was performed at Laboratoire Qualité & Soutien Exploitation de MLPC International to investigate the particle size distribution (granulometry) on 3 batches of the test substance EKALAND DPG PD (1,3 -diphenylguanidine). The study was conducted according to ISO 13320- 1 “International standard for Laser Diffraction Measurements – Principles of Laser diffraction” and in accordance with OECD Test Guideline 110. The mean particle size, number in volume, of DPG PD test item, is determined to be 26µm, with 10% of particles presenting a diameter less than 10µm, and 10% of particles presenting a diameter larger than 45µm.
