Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Justification for type of information:
- Performed on the liquid product as supplied
No possible to completely isolate from water and material products from attempts to dry were a sticky wax solid soluble in water and organic solvents making the evaluation of density considered to be impossible. - Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Principles of method if other than guideline:
- Three separate batches were evaluated.
The liquid was poured into volumetric containers and weighed. - GLP compliance:
- no
- Type of method:
- pycnometer method
- Remarks:
- Equivalent to pycnometer
- Key result
- Type:
- relative density
- Density:
- ca. 1.05 g/L
- Temp.:
- 25 °C
- Conclusions:
- Density of the liquid supplied was measured to be just greater than 1
Measured at 25 C, but not considered to make a major impact on the results. - Endpoint:
- density, other
- Remarks:
- density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- GLP compliance:
- no
- Type of method:
- pycnometer method
- Specific details on test material used for the study:
