Description of key information

A reliable study (Klimisch 1) to determine the ready biodegradability for the test substance, 4,4’-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene), measured <5% degradation after 28 days, and should be classified as not readily biodegradable under the conditions of the test.

Additional information

A reliable study (Klimisch 1) to determine the ready biodegradability for the test substance, 4,4’-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene), measured <5% degradation after 28 days, and should be classified as not readily biodegradable under the conditions of the test.

The test substance had no inhibitory effect on degradation and the reference chemical, sodium benzoate, was degraded by >60% after 14 days.

The test validity criteria were met and there were no significant deviations noted to affect the integrity of the study. This study is considered acceptable and satisfies the guideline requirements for a biodegradation in water: screening test.
