Results and discussion
Any other information on results incl. tables
Estimated rate constant: 22.43355E-12 cm3/molecule.sec
Half-life: 17.2 hours
The half-life is calculated from the rate constant, and assumes an OH radical concentration of 5E+05 OH molecules/cm3) (global average value,
obtained from EU Technical Guidance for environmental risk assessment).
Branched components, present in the substance within the limits described in section 1.1-1.4, may be photodegraded slightly faster than linear
components of equivalent carbon number, but the reported half-life represents a reasonably conservative estimate for this substance.
Applicant's summary and conclusion
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.
