Link to relevant study record(s)

Reference

Endpoint:

particle size distribution (granulometry)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

22 Aug 2017

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

comparable to guideline study with acceptable restrictions

Principles of method if other than guideline:

Particle size distrubution was performed by sieving the waxy flakes with filters of different mesh sizes and weighing the residual substance on each sieve.

GLP compliance:

no

Type of method:

sieving

Type of particle tested:

agglomerate

Type of distribution:

mass based distribution

Percentile:

other:

Remarks on result:

not determinable because of methodological limitations

Individual Results

Mesh size	Remaining substance (g)	Result (%)
5 mm	3.11	3.08
3 mm	22.49	22.27
2 mm	42.08	41.66
1.5 mm	15.53	15.38
0.43 mm	14.43	14.29
0.2 mm	2.65	2.62
0.15 mm	0.24	0.24
0.1 mm	0.32	0.32
0.071 mm	0.15	0.15
TOTAL:	101.0	100.0

Final Results

The major part of the sample (82.39 wt%) has a particle size ≥ 1.5 mm. The range of the particle size is 0.071 mm to 5 mm. The waxy flakes contain a maximum of 0.15 wt% material with a diameter < 100 µm.  No particle is below a diameter of 71 µm.

Description of key information

Range of the particle size is 0.071 mm to 5 mm (sieve method).
