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.
