Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Key result
- Type:
- bulk density
- Density:
- 1.284 other: g/ml
- Temp.:
- 20 °C
- Conclusions:
- Solid density measurements-DMSO: Mean value 1.284 g/ml
Solid density measurements-Formic acid: Mena value 12.285 g/ml - Executive summary:
Density was determined in duplicate in the test item with the capillary stoppered pyknometer for solids (without expansion chamber) at 20 ± 0.5 C, according to procedure PEBPL/MUNLAB/10 (CIPAC MT 3.2.1, guideline EEC A3) and employing dimethyl sulfoxide (DMSO) and formic acid as solvent. The first substance (DMSO) was slightly yellow coloured, so the test was repeated with formic acid. The results were very similar in both cases.
