- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.002 Pa
- Remarks on result:
- other: (i.e., equivalent to < 1.1 x 10-5 mm Hg)
- Key result

- Conclusions:
- Under the study conditions, the vapour pressure was determined to be <0.0015 Pa (i.e., equivalent to <1.1 x 10E-5 mm Hg) at 20°C and <0.0058 Pa (i.e., equivalent to <4.3 x 10E-5 mm Hg) at 25°C.
- Executive summary:
A study was conducted to determine the vapour pressure of the test substance, Coco TMAC (98.4% active) by isothermal thermogravimetry (effusion method), according to OECD 104, EU Method A.4 and EPA OPPTS 830.7950 Guidelines, in compliance with GLP. Under the conditions of the study, the vapour pressure was determined to be <0.0015 Pa (i.e., equivalent to <1.1 x 10E-5 mm Hg) at 20°C and <0.0058 Pa (i.e., equivalent to <4.3 x 10E-5 mm Hg) at 25°C (Brekelmans, 2012).

Description of key information
Under the study conditions, the vapour pressure was determined to be <0.0015 Pa (i.e., equivalent to <1.1 x 10E-5 mm Hg) at 20°C and <0.0058 Pa (i.e., equivalent to <4.3 x 10E-5 mm Hg) at 25°C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.006 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure was determined using the effusion method (isothermal thermogravimetry) according to OECD Guideline 104 and EU Method A.4 and/or EPA OPPTS 830.7950 (Brekelmans, 2012).
