Endpoint:

hydrolysis

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

In accordance with the column 2 adaptation of the information requirements for Annex VIII of REACH, the hydrolysis as a function of pH study does not need to be conducted if: - the substance is readily biodegradable, or - the substance is highly insoluble in water. The substance was determined to be inherently biodegradable after attaining 49 % degradation after 28 days calculated from oxygen consumption values in modified OECD guideline 301 F study. As pre-exposed inoculum was used in this test, the criteria for ready biodegradability given in the OECD Guidelines do not apply, however it is considered that the test material has exhibited the potential for significant degradation to occur in the environment. Therefore, hydrolysis as a function of pH has not been determined as it is not considered to be scientifically necessary.
