Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of Sodium surfactin is 0.0312 Pa at 75 °C.
- Executive summary:
The vapour pressure of Kaneka Surfactin was determined according to OECD 104 resp. EU A.4 using the effusion method (weight loss).
Vapour pressure was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible or relevant weight loss.
As a calculation on base of the measured weight losses is not possible, the highest vapour pressure, derived from all measurements, is stated as limit value.
The vapour pressure of Sodium surfactin is 0.0312 Pa at 75 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
