Description of key information
The vapour pressure of 2-Methyl-p-phenylenediaminesulfate (Haarbraun) was determined following guideline OECD 104.
Vapour pressure of the test material was determined by effusion method (vapour pressure balance). The temperature range was within the range of 21 to 150°C.
No vapour pressure of the test material was observed in the entire temperature range measured, meaning that the vapour pressure in the whole range was below the lower detection limit of 0.001Pa.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of 2-Methyl-p-phenylenediaminesulfate (Haarbraun) was determined following guideline OECD 104.
Vapour pressure of the test material was determined by effusion method (vapour pressure balance). The temperature range was within the range of 21 to 150°C.
No vapour pressure of the test material was observed in the entire temperature range measured, meaning that the vapour pressure in the whole range was below the lower detection limit of 10-5 hPa.
Conservative estimation of the vapour pressure of the test material using Antoine equation was:
5.94 x 10-11 hPa at 20°C
1.15x10-10 hPa at 25°C
2.28 x 10-9 hPa at 50°C
The vapour pressure of Haarbraun is far below 10(-7) hPa (based on a lack of any detectable vapour pressure at 149.5°C).
This vapour pressure test is classified as acceptable, and satisfies the guideline requirements for the OECD 104.
