Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Molecular formula:
C18H38 C20H42 C22H46 C24H50
IUPAC Name:

Results and discussion

See discussion and remarks in conclusion and executive summary sections below.

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.
