Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The chronic toxicity of 3-aminopropyldimethylamine (CAS 109-55-7) was assessed in a semi-static 22-d reproduction test according to OECD 211, using Daphnia magna as test species. The test substance concentrations were analytically verified. The initial test concentrations and those after 48 and 72 hours of exposure deviated less than 20% from the nominal concentrations, except for samples of one test concentration on day 19, which deviated more than 20% from the nominal concentration. Therefore, the results are based on time-weighted average concentrations. All validity criteria were fulfilled. After 22 days, a NOEC (reproduction) of 3.64 mg/L was determined, based on time-weighted average concentrations (BASF SE, 2017, report no.: 51E0340/15E017).
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.
