Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Similar toxicokinetic behavior and toxicity profile
All category members are subject to enzymatic hydrolysis by pancreatic lipases resulting in free acids and alcohol. Based on current literature, when absorbed from intestines and carried through blood stream, fatty acids are oxidized by beta-oxydation pathway in order to provide energy for cell and stored as glycerides esters in fat deposit. The alcohols are primarily metabolized in the liver.
Hence, it can be stated that the members of the category have the same toxicity due to the same metabolic pathways when absorbed in the organisms.
Based on the available data for in vivo micronucleus test, no genotoxicity was observed on the tested source substance including in the category. Hence, according to the physico-chemical similarities between the substances of the category, the registered substance 2-ethylhexyl isostearate could be considered as not genotoxic in in vivo micronucleus test.
Applicant's summary and conclusion
- Conclusions:
- Based on the available data for in vivo micronucleus test, no genotoxicity was observed. Hence, the registered substance 2-ethylhexyl isostearate could be considered as not genotoxic in in vivo micronucleus test
