1) mean value of triplicate measurements (at 35 °C duplicate measurements only)
A preliminary test showed that a sample of the test item had already vaporized before measurement when degassing the sample at 60 DC. Thus the sample was degassed at 30 DC but for a longer period and the measurements started already at 16 DC.
The vapour pressure of the test item at 20 DC was interpolated graphically in the log pvs 1/Tplot. It corresponds to the measured value at 20 DC of 3.2 • 10-3hPa.
Description of key information
In a valid guideline study acc. OECD 104 with vapour pressure balance method the vapour pressure of Butyldiglycol methacrylate was 0.32 Pa
at 20 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.32 Pa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
