- Key result
- Percentile:
- D10
- Mean:
- 20.54 µm
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Key result
- Percentile:
- D90
- Mean:
- 82.09 µm
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Remarks on result:
- not measured/tested
- Conclusions:
- The particle size of Spinomar NaSS (sodium p-styrenesulfonate) was measured. The median of the particle size was 48.84 micrometer, and its standard deviation is 22.93 micrometer. Standard deviation is defined as SD = (D84% - D16%)/2.
- Executive summary:
The particle size of Sodium p-vinylbenzenesulphonate was measured by lazer diffraction method. The median of the particle size was 48.84 micronmeter (D50%), and its standard deviation was 22.93 micronmeter.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
