Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Category name:
Fatty Acid SCAE Ethyl-, Isopropyl-, Butyl- and 2-Ethylhexyl-Esters (SCAE C2-C8)

Justifications and discussions

Category definition:
Short chain fatty acid esters with ethanol, butanol, and 2-ethylhexanol
Category description:
Category contains ethyl, isopropyl, butyl and 2-ethylhexyl esters. The number of carbon atoms in the fatty acid chains (all even-numbered) ranges from C8-C22. The total number of carbon atoms ranges from 15 to 26.
Category rationale:
The category comprises of ethyl, iso-propyl, butyl and 2-ethylhexyl esters, hence the alcohol moiety contains 2-8 carbon atoms. Altogether, the total number of carbon atoms varies between 15 (isopropyl dodecanoate, CAS No. 10233-13-3) and 26 (ethylhexyl octadecenoate, CAS No. 26399-02-0; this substance or its hydrogenated analogue ethylhexyl octadecanoate are also present in three UVCB chemicals: CAS No. 135800-37-2, 91031-48-0 and 85049-37-2). All category members contain only even numbered fatty acid chains, from C8 to C22. In each of 4 subclasses, physico-chemical data aligns in trends with respect to the number of carbon atoms in acid moiety; there are also observed general trends related to the total number of carbon atoms.
