Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
The results of the screening test show that the absorption of the test substance could only be determinated for Eurosoil 1. For Eurosoil 2-5 the values of the concentrations of Irganox 1520 in equilibrium state were below the detection limit. Therefore the adsorption as well as the Koc values could only be estimated from the detection limit.
On the basis of the results of the study, the substance did not show significant adsorption potential to soil. The substance is therefore not considered to have a strong propensity to adsorb to soil.
