Results and discussion
Half-life / dissipation time of parent compound
- Type:
- (pseudo-)first order (= half-life)
- Details on results:
- Extracted amines at day zero:
a) EtAc-MeOH: 67%
b) NH4OAc: 12.3%
c)NaOH: 8.4%
Sum: 87.7%
Extracted amines after 63 d incubation period:
a) EtAc-MeOH: 13.0% +/- 4.5%

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.
