Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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 toDirective 67/548/EEC or Directive 1999/45/EC or CLP-Regulation (EC) No 1272/2008or 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.  

 

 

No studies on the toxicity to birds are available for the substance.  

In Annex X Section 9.6.1 of Regulation (EC) No 1907/2006, it is laid down that any need for testing should be carefully considered taking into account the large mammalian dataset that is usually available at this tonnage level. In case of

3-Aminopropyldimethylamine (CAS 109-55-7) a mammalian dataset is available. In addition, the hazard assessment of the substance reveals neither a need to classify the substance as dangerous to the environment according to Directive 67/548/EEC or Directive 1999/45/EC or CLP-Regulation (EC) No 1272/2008, 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 (see IUCLID Ch. 5.2.1). Based on the low estimated BCF values, bioaccumulation in organisms is not to be expected (see IUCLID Ch. 5.3.1).    

Consequently, no tests on birds are performed.
