Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
According to REACH Regulation 1907/2006/EC, Annex IX section 9.3.2
column 2 a study for bioaccumulation in aquatic species, preferably fish
need not be conducted if no direct or indirect exposure to the aquatic
environment is expected.
At production sites, the ester is handled in closed systems for
polymerisation. Diffuse releases into the environment from residual
monomers in the polymeric products are not of concern due to the
extremely low vapour pressure of the substances. Direct and indirect
exposure of the test item to water is highly unlikely. Thus no test is
required.
Key value for chemical safety assessment
- BCF (aquatic species):
- 323.6 L/kg ww
Additional information
Bioaccumulation
Bioaccumulation: aquatic/ sediment
According to REACH Regulation 1907/2006/EC, Annex IX section 9.3.2 column 2 a study for bioaccumulation in aquatic species, preferably fish need not be conducted if no direct or indirect exposure to the aquatic environment is expected.
At production sites, the ester is handled in closed systems for polymerisation. Diffuse releases into the environment from residual monomers in the polymeric products are not of concern due to the extremely low vapour pressure of the substances. Direct and indirect exposure of the test item to water is highly unlikely. Thus no test is required.
In the supporting study to 2-Propenoic acid, octadecyl ester the bioaccumulation potential of the test substance was calculated to be 323.6 L/kg or log BCF = 2.510 using the EPA Epiwin (v.4.11) software. According to Annex XIII a substance does not fulfil the Bioaccumulation criterion (B-) when the bio concentration factor (BCF) is lower than 2000, therefore a test for bioaccumulation: aquatic/sediment to 2-Propenoic acid, octadecyl ester does not need to be conducted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
