Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
The test substance is not supposed to be directly applied to soil and an indirect exposure to soil via sewage sludge transfer is unlikely
since the substance is readily biodegradable. For a substance being considered as „readily biodegradable“, it can be assumed that it will be biodegraded within the STP process and as a consequence a transfer to the soil compartment is not expected. Therefore, no tests on terrestrial organisms are provided.
Moreover, in accordance with Regulation (EC) No.1907/2006, Annex 1, Section 6.4, the chemical safety assessment for 1-(2-hydroxypropylamino)propan-2-ol demonstrates that 1) the exposure levels estimated in all relevant scenarios do not exceed the appropriate PNEC, and 2) the likelihood and severity of an event occurring due to the physicochemical properties of the substance in the soil and the aquatic environment are negligible; therefore, the criteria for adaptation are met.Specifically, all risk characterization ratios are under 1.0; and there are no physicochemical hazards identified for this substance in soil and the aquatic environment. Therefore,no tests on terrestrial organisms are indicated.
However, a NOEC of 424 mg/l for the root growth of Daucus carota and Lactuca sativa in sandy soil was determined (Nagpal, 2003).

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.
