Description of key information

The test substance 2-oxepanone, polymer with 1,4-butanediol has been found to the readily biodegradable with 60% degradation within 7 days when incubated at a concentration of 10 mg/L and 42% degradation when incubated at a concentration of 20 mg/L. As such, removal in the environment is expected to be rapid and so further information on abiotic removal, transport and distribution are not required. A hydrolysis study concluded that 2-oxepanone, polymer with 1,4-butanediol is hydrolytically stable.

There is no risk of persistence in the environment and biological removal processes will be rapid with complete mineralization expected in a short time frame due to biodegradation.

2-Oxepanone, polymer with 1,4-butanediolhas a log Kow of 2.5 and so no significant adsorption or potential for bioaccumulation is expected.

2-Oxepanone, polymer with 1,4-butanediol has a low vapour pressure of less than 1 Pa at 25 °C. As such no significant partitioning to air will occur.
