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.
