- Key result
- Type:
- relative density
- Density:
- 0.967 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: relative density at 20 °C in reference with water at 4 °C
- Conclusions:
- The relative density at 20°C/4°C of nopol (CAS No. 35836-73-8) was determined to be 0.967.
- Executive summary:
The determination of the relative density was performed in accordance with Regulation (EC) No 440/2008, method A.3 “Relative density” (May 2008) and OECD Guideline No 109 “Density of liquids and solids” (July 1995).
The oscillating densitimeter method was used.
Three measurements were performed at 20°C ± 0.5°C. The relative density 20°C/4°C of nopol was determined to be 0.967.
Reference
The obtained value is the mean result of three determinations at 20 ± 0.5 °C:

Relative density = density (kg/m3) / 999.975 (kg/m3) (density of water at 4°C).
The average density at 20°C ± 0.5 °C of the test item is 967 kg/m3.
Description of key information
The density was determined with an oscillating densitimeter.
The relative density 20°C/4°C of nopol is 0.967.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.967
Additional information
Key study conducted according to OECD 109 Guideline and EU Mehod A.3. The result is scientifically acceptable but not obtained under GLP.
Therefore a reliability of 2 (reliable with restrictions) is assigned.
