Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

No carcinogenicity tests have been conducted on C6-C18 alpha or internal olefins. However, there

are no structural alerts indicating a potential for carcinogenicity in humans.

For analogy, long-term carcinogenicity studies have been conducted for alpha olefin sulfonates (AOS) derived 
from alpha olefins of similar alkyl   length. For example, Hunter and Benson (1976) fed rats mixed C14-16 AOS   
at dietary levels of 1000, 2500, and 5000 ppm for two years. 
Blood chemistries, urinalyses, and histopathological findings were comparable to control values.
There was no increase in tumors from the feeding of the test article.
Three carcinogenicity studies of AOS reported by Oba and Takei (1992)
indicated that these AOS were not carcinogenic by oral or dermal routes.

Furthermore, negative results were seen in UDS and transformation assays concucted with Hexene, Octene,

C12 -16 olefin fraction, Tetradecene, and Hexadecene.
