Description of key information
The vapour pressure of MDEA Esterquat C18 satd. is calculated to be < 1E-09 Pa at 25°C (lowest accepted value by IUCLID as key value for chemical safety assessment).
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
According to REACH regulation (Annex XI, 2.), the vapour pressure does not need to be determined if the measurement is technically not feasible due to the substance properties. MDEA Esterquat C18 satd. represents a ionic solid at standard conditions (20°C, 1013 hPa), therefore a very low vapour pressure is to be expected.
As low residual amounts of solvent are part of the substance, the vapour pressure of MDEA Esterquat C18 satd. itself cannot be experimentally determined.
As supporting data, a calculation is provided: the vapour pressure of MDEA Esterquat C18 satd. was calculated to be 7.33E-18 Pa at 25°C (EpiSuite V4.11, MPBPVP v1.43, Modified Grain method).
The vapour pressure is lower than the lowest value accepted by IUCLID in the field "Key value for chemical safety assessment" (1E-09 Pa), thus this lowest accepted value was selected as key value for chemical safety assessment.
