- Executive summary:
A study was conducted to determine the particle size distribution of the test substance, mono- and di- C16 PSE, K+ H3PO4, according to ISO 17892-4 : 2004, using granulometry by sieving method. The sieves were stacked in mesh size order from largest aperture (top - 600 µm) to smallest aperture (bottom - 63 µm) and the sample aliquot weighed into a glass bowl (50.3142g). This was emptied into the top sieve and the bowl brushed out with a soft brush. The stack of sieves were placed on a mechanical shaker for 5 minutes at 95 rpm followed by 2 minutes manual agitation. The sieves were turned by 45° after each minute of shaking. Sieves were then removed consecutively from the stack and the contents carefully transferred to a weighing bowl. The sieve was brushed down with a soft brush to ensure quantitative transfer of material. The sample was analysed using the sieve method down to an aperture of 63 µm. Analysis of the sample fraction passing through this mesh (20.147% of sample mass) has not been carried out and would require alternative methodology. 1.592% of the sample mass did not pass the 600µm sieve, the largest aperture used. Visual examination of the retained particles indicated that these were all marginally larger than the sieve mesh and there were no anomalously large particles or agglomerations present. The particle sizes of the sample therefore formed a continuous and consistent distribution. The recovery of test substance from the experiment was 99.4%. Therefore, the validity criteria for this study (>99% recovery) was met. Under the study conditions, the particle size distribution of the test substance was determined continous and consistance (600 to 63 µm) (Chemex, 2018).

Discussion
The sample was analysed using the sieve method down to an aperture of 63 µm. Analysis of the sample fraction passing through this mesh (20.147% of sample mass) has not been carried out and would require alternative methodology. 1.592% of the sample mass did not pass the 600 µm sieve, the largest aperture used. Visual examination of the retained particles indicated that these were all marginally larger than the sieve mesh and there were no anomalously large particles or agglomerations present. The particle sizes of the sample therefore formed a continuous and consistent distribution. The recovery of test substance from the experiment was 99.4%. Therefore, the validity criteria for this study (>99% recovery) was met.
Description of key information
The particle size distribution of the test substance was determined according to ISO 17892-4:2004, using granulometry by sieving method (Chemex, 2018).
