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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Principles of method if other than guideline:
- The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.3 and OECD Test Guideline 109.
The relative density of solids or liquids is the ratio between the mass of a volume of substance to be examined, determined at 20°C, and the mass of the same volume of water, determined at 4°C. The relative density has no dimension.
The density, ρ, of a substance is the quotient of the mass, m, and its volume, v.
The density, ρ, is given, in SI units, in kg/m3.
For solids or liquids, pycnometers of various shapes and with known volumes may be employed. The density is calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests are run at a constant temperature, preferably 20°C, and at least two measurements are generally performed. - GLP compliance:
- no
- Type of method:
- pycnometer method

The density of SMLT was determined in accordance with the pycnometer procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.3 and OECD Test Guideline 109.
Mean result from 2 runs:
Relative density = 1.193 @ 20°C
Density = 1.193 g.cm-3 @ 20°C

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.
