Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
No studies on terrestrial organisms are available for 3
-aminopropyldimethylamine (CAS 109-55-7). In Annex X Section 9.4 of
Regulation (EC) No 1907/2006, it is laid down that tests on terrestrial
organisms shall be proposed by the registrant if the chemical safety
assessment indicates the need to investigate further the effects on
terrestrial organisms. According to Annex IX and X, the choice of the
appropriate tests depends on the outcome of the chemical safety
assessment. According to Annex I of this regulation, the chemical safety
assessment triggers further action when the substance or the preparation
meets the criteria for classification as dangerous according to
Directive 67/548/EEC or Directive 1999/45/EC or CLP-Regulation (EC) No
1272/2008 or is assessed to be a PBT or vPvB.
The hazard assessment of the substance reveals neither a need to
classify the substance as dangerous to the environment, nor is it a PBT
or vPvB substance, nor are there any further indications that the
substance may be hazardous to the environment. In addition, indirect
exposure to the soil compartment is unlikely since the substance is
readily biodegradable according to OECD criteria. For substances being
considered as „readily biodegradable“, it can be assumed that they will
be biologically degraded within the STP-process. As the log Koc of the
substance is below 3, a low adsorption potential is indicated (see
IUCLID Ch. 5.4.1). Hence, an adsorption to activated sludge is unlikely.
Based on the low estimated BCF values, bioaccumulation in aquatic
organisms is not to be expected (see IUCLID Ch. 5.3.1).
Consequently, no tests on soil organisms are performed.
The equilibrium partitioning method has been used for assessing the
hazard to soil organisms in accordance with Annex IX, Section 9.4,
Column 2 of Regulation (EC) No 1907/2006.
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.
