Description of key information

No studies on terrestrial organisms are available for octanolamine.

Key value for chemical safety assessment

Additional information

Octanolamine is readily biodegradable, highly water soluble and has a very low potential for adsorption to organic matter. Therefore, the predicted no effect concentration (PNEC) for soil was derived from the PNEC for freshwater using the equilibrium partitioning method. This method is applicable for substances where the toxicity in soils relates to the freely dissolved concentration in pore water. According to REACH Annex IX and X requirements (column 2), studies on terrestrial organisms do not need to be conducted, if direct and indirect exposure of the soil compartment is unlikely. The risk characterisation shows that the PEC/PNEC ratio for soil is clearly <1, indicating no need for further information and testing. Hence testing of effects on terrestrial organisms can be waived.
