Description of key information

Additional information

The test substance 5-ethyl-1,3-dioxane-5-methanol has been found to the readily biodegradable with biodegradation rates over 90% being observed in both the key and supporting studies. 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 CTF 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.

5-ethyl-1,3-dioxane-5-methanol has a low log Kow of 0.19 and so no significant adsorption or potential for bioaccumulation is expected.

5-ethyl-1,3-dioxane-5-methanol has a low vapour pressure of 1.4 Pa at 25 degrees Celsius. As such no significant partitioning to air will occur.
