Additional information
Stability
Phototransformation in air
Degradation rates for gas-phase reactions of the test substance with hydroxyl radicals and ozone in the atmosphere were calculated using the AOPWIN program, v1.92.
The calculated degradation rate of the test substance with hydroxyl radicals (OH) is 1.40973 x 10E-11 cm3/molecule/sec and with ozone 3x 10E-20 cm3/molecule/sec. The atmospheric degradation half-life of the test substance due to reactions with OH radicals is 0.759 days.
The atmospheric degradation half-life of the test substance due to reactions with ozone is 382 days.
Biodegradation in water: screening test
In the GLP and OECD 301 B guideline compliant ready biodegradability study the test substance (57% solution) was tested for ready biodegradability. Based on the rate of biodegradation of 30-40 % CO2/ThCO2 at the end of exposure the test substance can be evaluated as moderately or partly biodegradable.
Transport and distribution
Adsorption/desorption
The logKoc was determined to be 0.4653 using KOCWIN v2.00 MCI methodology.
The logKoc was determined to be 0.5137 using KOCWIN v2.00 log Kow method.
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.
