Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- Principles of method if other than guideline:
- Dynamic viscosity (Ƞ) of a Newtonian solvent is generally measured by viscosimeters. Rheometers are used to measure the flow behaviour of viscous fluids, including oils.[1] In this study, Ƞ was calculated by using a rotational rheometer which has recorded changes in solvent viscosity with temperature (°C). Ƞ is measured in Pa s or mPa s (cp).

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).
