Results and discussion

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
Direct photolysis will not contribute to the degradation of reaction products of 1-decene, 1-dodecene, and 1-octene, hydrogenated in the terrestrial  environment because the test substance does not absorb light at wavelengths >290 nm which contributes to the phototransformation process in that compartment.
Executive summary:

The registered substance is a fully saturated branched alkane hydrocarbon material that does not absorb light within a range of 290 to 750 nm. Therefore, direct photolysis will not contribute to the degradation of the reaction products of 1 -decene, 1 -dodecene and 1 -octene hydrogenated in the terrestrial compartment because it does absorb light at wavelengtjs > 290 nm.
