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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 268-103-5 | CAS number: 68002-88-0 This substance is identified by SDA Substance Name: C16-C22 alkyl carboxylic acid and SDA Reporting Number: 21-005-00.

Description of key information
The partition coefficient log Pow is between 6.96 - 9.91 (range of log pow of the single constituents of the mixture).
Key value for chemical safety assessment
Additional information
There is company data for the partition coefficient available for the Fatty acids, C16-22, which indicates a log Pow > 5 (estimated, Oleon NV 2010).
The range of the partition coefficient (log Pow) is estimated by using a category approach based on the available QSAR data for its main constituents (palmitic acid: CAS 57-10-3, stearic acid: CAS 57-11-4, icosanoic acid: CAS 506-30-9 and docosanoic acid: CAS 112-85-6, with an increasing log Pow as the chainlength increases).
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.
