Description of key information
Isodecanol can exhibit a high extent of biodegradability in soil, based on unacclimated and acclimated studies. Up to 99% biodegradation was measured based on CO2 evolution after 12 days under unacclimated conditions and a test substance concentration of 100 mg/Kg soil. The half-life was approximately 4 days. Under acclimated conditions and a test substance concentration of 1000 mg/Kg soil, isodecanol exhibited 67% biodegradation based on CO2 evolution and 99% biodegradation based on test substance analyses. The half-life was approximately 21 days at the higher soil loading.
Key value for chemical safety assessment
- Half-life in soil:
- 4 d
- at the temperature of:
- 293.15 K

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
