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 has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter

Description of key information

Based on a log Pow of < -2.7 (at 20 °C EU Method A.8, estimation method) adsorption/desorption is not expected to be an important process.

Key value for chemical safety assessment

Additional information

There is no study available on adsorption/desorption for Sodium 2 -butoxyethyl sulfate (CAS 67656-24-0). In accordance with column 2 of Regulation (EC) 1907/2006 Annex VIII the testing is not required since the substance can be expected to have a low potential for adsorption based on a log Pow of < -2.7.
