Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence Assessment
Based on the structure in Benzyldimethylamine no hydrolysable groups are present. The substance can thus be regarded as hydrolytically stable.Benzyldimethylamine was shown to be 100 % inherently biodegradable after 13 days and to 70% within 7 days and thus fulfilled the criterion for inherent, ultimately biodegradability (BASF, 1987).
Thus, Benzyldimethylamine was not considered persistent.
Bioaccumulation Assessment
Benzyldimethylamine was determined to be none or not highly bioaccumulative. The BCF at a concentration of 500 µg/L is 2.1 to 6.4, and at a concentration of 50 µg/L the BCF is < 6.2 to 22 (MITI-Online, MITI-Buch, 1992).
Thus, Benzyldimethylamine was not considered bioaccumulative.
Toxicity Assessment
Based on the results of the toxicity assessment, Benzyldimethylamine does not fulfil the toxic criterion as the NOEC in Daphnia and algae was determined to be > 0.01 mg/l.
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.
