Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- not specified
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, but without detailed documentation (uncertainty on test temperature). The substance identification is not complete (composition missing). Therefore validation applies with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- GLP compliance:
- no
- Type of method:
- capillary viscometer (static)
- Standard covering the apparatus used:
- ISO 3105
- Key result
- Temp.:
- 40°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 3.94
- Conclusions:
- Fluid liquid.
Based on CLP criteria, the substance has potential for Aspiration Hazard (< 20.5 mm2/s at 40°C and hydrocarbon). - Executive summary:
The viscosity of the test substance was measured according to OECD114 guideline, capillary method.
Five measurements of flow time were recorded at the supposed temperature of 40°C, and the mean result is retained.
The kinematic viscosity of the substance at 40°C is 3.93 mm2/s.

Description of key information
Fluid liquid. Potential for Aspiration Hazard.
Key value for chemical safety assessment
- Viscosity:
- 3.94 mm²/s (static)
- at the temperature of:
- 40 °C
Additional information
A reliable experimental study,conducted according to a recognized OECD method, is available. Despite restrictions due to substance characterisation, and on test temperature, it is considered as a key study. The result is retained as key data.
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).
