Description of key information

Not readily biodegradable: 0% (TOC) in 28 days, 0 - 5% (GC) in 28 days (equivalent to OECD TG 301C)

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

There is one reliable study on biodegradation of 1,1,1,3,3,3-hexafluoro-2-propanol. Biodegradation of 1,1,1,3,3,3-hexafluoro-2-propanol by an activated sludge in 28 days was tested according to national standard (equivalent to OECD TG 301C). Because the test substance is volatile substance and has a reactivity with the soda lime, the measurement of BOD (Biochemical Oxygen Demand) is impossible.

The determination by the TOC and GC methods showed 0% and 5% degradation of 1,1,1,3,3,3-hexafluoro-2-propanol, respectively. Therefore 1,1,1,3,3,3-hexafluoro-2-propanol is not considered readily biodegradable under the test condition.
