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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Parent compound: stearoyl chloride: based on BCF-estimate accumulation in organisms is possible.
Hydrolysis product: stearic acid: based on BCF-estimate significant accumulation in organisms is not expected
Key value for chemical safety assessment
Additional information
Stearoyl chloride has an estimated log Kow of 7.39 (BASF SE, 2009). The corresponding BCF estimate is 2181 (BASF SE, 2009), therefore accumulation in organisms is possible. However the test substance rapidly hydrolyses and forms stearic acid. Hence, the BCF-estimate may be of low relevance.
The hydrolysis product stearic acid has an experimentally determined log Kow of 8.23 (Sangster, 1993). Therefore based on log Kow accumulation in organisms is possible. However, the BCF was estimated to be 10 (BASF SE, 2009) and ca. 20 (BASF SE, 2010) using EPIWINv4.00 and Catabol - BCF base-line model (v01.04), respectively. Based on these BCF-estimates, significant accumulation in organisms is not expected.
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.
