Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Justification for type of information:
Performed using density meter at 38 C. Although this is a higher temperature than is required according to guidelines, the difference in density between 20 and 38 C will not impact on the risk assessment.
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Version / remarks:
Performed using density meter at 38 C
GLP compliance:
no
Type of method:
oscillating densitimeter
Specific details on test material used for the study:
A representative sample (#BP16120710) was stripped of as much water as possible to make batch referred to as PAH/225/134/5 to use for testing.
An FTIR was ran on sample #BP16120710 and PAH/225/134/5 to ensure that no degradation occurred during the removal of the solvent.
Type:
relative density
Density:
ca. 1.19 g/cm³
Temp.:
38 °C
Type:
relative density
Density:
> 1.2 g/cm³
Temp.:
20 °C

Testing was performed at 38 C; the reason is understood to be that viscosity was too high at lower temperatures .

Therefore, it is concluded that the density at 20C will be > 1.19

The result is academic since the substance will not normally be removed from water

Conclusions:
Testing was performed at 38 C; the reason is understood to be that viscosity was too high at lower temperatures .
Therefore, it is concluded that the density at 20C will be > 1.19
The result is academic since the substance will not normally be removed from water
