Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

adsorption / desorption: screening
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly

Description of key information

Study scientifically unjustified.

Key value for chemical safety assessment

Additional information

The performance of the adsorption/desorption screening test is scientifically unjustified. REACH Regulation (EC) No 1907/2006, Annex VIII Sect. 9.3.1., Col. 2, states as follows:

"9.3.1. The study does not need to be conducted if:

– based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient); or

– the substance and its relevant degradation products decompose rapidly."

Due to rapid decomposition (hydrolysis) of the test substance upon contact with water and its inherent biodegradability, measurement of the adsorption behaviour of the test substance is technically not feasible.
