Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

To establish a PNECsoil as apart of a quantitative assessment of risk to the soil compartment, the equilibrium partitioning method (EPM) is used. 

Key value for chemical safety assessment

Additional information

Several studies of the toxicity of adipic acid towards terrestrial plants were found in the literature.

The scope of the terrestrial effects assessment under the adopted REACH regulation is restricted to soil organisms in a narrow sense and does not actually include adverse effects on soil functions that are only indirectly linked to the biota in soils. All tests described above, were designed assessing the influence of adipic acid on germination and growth on moist filter paper or agar treated with the substance. As no soil was used in the tests standardisation of soil effect data to given soil parameters is not possible. Further, converting the results to an appropriate dimension is not applicable. Therefore the results should not be used for the hazard assessment. Nevertheless, the obtained effect values indicate that adipic acid is of low toxicity to terrestrial plants
