Description of key information

10% biodegradation after 29 days (CO2 evolution) (OECD 301B)

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

One ready biodegradation study is available for 3-cyclohexyloxypropane-1,2 -diol (CAS No. 10305 -41 -6). This key study was carried out following OECD Guideline 301B and according to GLP (Desmares-Koopmans, 2013). Under aerobic conditions the test substance was incubated with the inoculum containing microorganisms from a domestic sewage plant. After the test period of 29 days, biodegradation reached 10%, based on CO2 evolution. In conclusion, 3-cyclohexyloxypropane-1,2 -diol (CAS No. 10305 -41 -6) can be considered as not biodegradable under the test conditions according to OECD criteria.
