- male/female
- Dose descriptor:
- LC0
- Effect level:
- 0.2 mg/L air
- Exp. duration:
- 8 h

No LC50 value defined; Substance concentration in the vapour was determined by weighing the amount of substance in the substance column before and after the exposure period and calculating the mean concentration per liter air over the whole exposure period.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
