Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable

Description of key information

The substance is rapidly biodegradable and will therefore be quickly eliminated in sewage treatment plants and the environment in case of release. Due to rapid biodegradation of the substance, primary degradation via hydrolysis is not considered as a main degradation process.

Key value for chemical safety assessment

Additional information

There is no study available on hydrolysis for sodium 2 -butoxyethyl sulfate (CAS No. 67656 -24 -0). In accordance with Regulation (EC) 1907/2006, Annex VIII Column 2, a test for hydrolysis as a function of pH does not need to be performed if the substance is readily biodegradable.
