Registration Dossier
Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substances of the category, including Isopropyl palmitate, have potential to bioaccumulate due to their physico-chemical properties, but are expected to be metabolised and excreted from fish quickly.
Key value for chemical safety assessment
Additional information
A BCF was calculated to be 913 L/kg wet weight (BCFBAF v3.00, regression based estimate) which indicates that accumulation in organisms is possible. When including biotransformation rate constants the BCF was lower at 31.38 L/kg (Arnot-Gobas estimate, including biotransformation, upper trophic).
If taken up into fish, linear fatty acid ester substances are expected to be rapidly metabolised and excreted. Due to their demonstrated potential for rapid metabolisation in fish, the category of linear aliphatic fatty acid esters has recently been categorised by Environment Canada as having low potential to bioaccumulate (SIDS Expoxidized Oils and Derivatives Category 2006), primarily due to the activity of the enzyme carboxylesterase.
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.
