- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:

- IUPAC nomenclature - Sodium diisobutyldithiophosphinate
- Lot WEA102051
- Appearance - White powder with lumps
- CAS No. 13360-78-6
- Molecular Formula - C8H18PS2.Na
- Molecular Weight - 232 g/mole
- Purity > 99% - Percentile:
- D10
- Mean:
- 23 µm

- other: St dev not specified
- Percentile:
- D90
- Mean:
- 195 µm
- St. dev.:

- Conclusions:
- Particle size of test substance is ~100 microns with particles ranging 10-1000 microns.
- Executive summary:
Particle size of test substance is ~100 microns with particles ranging 10-1000 microns.
Optical images show that particles are acicular to rectangular in shape. Note that particle size is performed on the test substance after being freeze dried and particle morphology and size may be a direct result of the freeze drying process.

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.
