Description of key information

Based on an OECD301D test as cited in the OECD SIDS, 2003 for 3 -aminopropyldimethylamine (CAS 109 -55 -7) the test substance was determined to be readily biodegradable but it failed the 10 -d window.

Therefore, data on the ready biodegradability from the structurally similar substance diethylaminopropylamine (CAS 104 -78 -9) were also considered. Diethylaminopropylamine is readily biodegradable in an OECD 301A test and hence, 3 -aminopropyldimethylamine is also considered to be readily biodegradable. Hence, no study is performed.

Additional information

According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.2, column 2, a simulation study on ultimate degradation in surface water does not need to be conducted if the substance is readily biodegradable. The substance is readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no biodegradation studies in surface water will be provided.

According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.4, Column 2, sediment simulation testing does not need to be conducted if the substance is readily biodegradable. The substance is readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no sediment simulation study will be provided.
