- key study
- Study period:
- 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: European Commission Guidance Document EUR 20268 ‘Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of Chemical Substances’, 2002.
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- sieving

- volumetric distribution
- Remarks on result:
- not measured/tested
- Percentile:
- D50
- Remarks on result:
- not measured/tested
- No.:
- #1
- Size:
- < 100 µm
- Distribution:
- 6.83 %
- Remarks on result:
- other:
- Remarks:
- percentage of material passing a 100 µm sieve was calulated based masses
- Conclusions:
- The percentage of FAT 36152/N having an inhalable particle size of less than 100 µm was determined to be 6.83 %. The test item has been considered to be essentially non-inhalable.
- Executive summary:
The proportion of FAT 36152/N having an inhalable particle size of less than 100 µm was determined by a sieve method to be 6.83 %, using a procedure designed to be compatible with the European Commission Technical Guidance Document EUR 20268 ‘Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of chemical substances’ (2002). The test item has been considered to be essentially non-inhalable.

Description of key information
The percentage of FAT 36152/N having an inhalable particle size of less than 100 µm was determined to be 6.83 %. The test item has been considered to be essentially non-inhalable.
Additional information
A study was performed to determine the particle size of FAT 36152/N using a procedure designed to be compatible with the European Commission Technical Guidance Document EUR 20268 ‘Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of chemical substances (2002). The proportion of FAT 36152/N having an inhalable particle size of less than 100 µm was determined by a sieve method to be 6.83 %. The test item has been considered to be essentially non-inhalable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
