CAS number: 102-06-7
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.
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.
