Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

To appraise the octanol/water partition coefficient of a complex reaction product (Isodecyl acrylate), this endpoint was experimentally measured in accordance with OECD testing guideline 117 and GLP requirements.

A range of octanol/water partition coefficient values at pH 6.44 was obtained: 5.03 to 5.96, 86.6% of the components have Log Pow ranged from 5.55 to 5.7.

Based on exposure scenarios, no exposure is expected on soil. The potential release in the environment is only through the aqueous phase. Therefore, the lowest log value of n-octanol/water partition coefficient (5.55) in the range representing 86.6% of the components is used for chemical safety assessment (CSA).
