Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to Regulation (EC) 1907/2006, Annex IX, Section 9.4.1 to
9.4.3, Column 2, studies on the toxicity to terrestrial organisms do not
need to be conducted if direct and indirect exposure of the soil
compartment is unlikely.
For tripropylamine only industrial and professional uses with adequate
risk mitigating measures are foreseen. Environmental exposure through
widespread uses by consumers is excluded. Widespread uses by
professionals will mostly take place indoors. In case of outdoor
scenarios, risk mitigating measures are implemented to reduce unintended
exposure to insignificant amounts. The substance is not supposed to be
directly applied to soil.
Tripropylamine is considered not readily biodegradable according OECD
criteria, however shown to be easily eliminated from water, after an
extended lag phase (see IUCLID Ch. 5.2.1). Therefore, an indirect
exposure to soil via sewage sludge transfer may be reduced since it can
be assumed that the substance will partly be biodegraded within the STP
process and as a consequence a transfer to the soil compartment is
minimized. Additionally, adsorption to sewage sludge is not expected
based on the low adsorption potential (see IUCLID Ch. 5.4.1); therefore,
further reducing the risk of indirect transfer of the substance via
sewage sludge.
In Annex XI, Section 3, it is laid down that testing in accordance with
Annex IX may be omitted, based on the exposure scenario(s) developed in
the Chemical Safety Report (“Substance-Tailored Exposure-Driven
Testing”). In accordance with Annex XI, Section 3, it can be
demonstrated in the risk assessment that the manufacture and the use of
the substance do not pose an unacceptable risk for all environmental
compartments as the risk characterization ratios (RCRs) of the chemical
safety assessment are well below 1 for all compartments (see Chemical
Safety Report Ch. 10).
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.
