Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from may 19, 2011 to july 12, 2011
- 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)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- 2010-12-15
- Type of method:
- air comparison pycnometer (for solids)
- Key result
- Type:
- relative density
- Density:
- 1.307
- Temp.:
- 20.6 °C
- Conclusions:
- The relative density mean value of the test item using the gas comparison method with the stereopycnometer was D (20.6°C / 4°C) = 1.307 ± 0.002
- Executive summary:
In a GLP study (Défitraces, 2011), the relative density of Ethylvanillin was determined using the gas comparison pycnometer, according to the OECD 109 guideline.
The relative density mean value of the test item was D (20.6°C / 4°C) = 1.307 ± 0.002.

Description of key information
The determined density was 1.307
Key value for chemical safety assessment
- Relative density at 20C:
- 1.307
Additional information
Only one GLP study, OECD 109 compliant, was available and was selected as key study. It was quoted with reliability 1 according to Klimisch scale.
