Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 271-653-9 | CAS number: 68603-38-3 This substance is identified by SDA Substance Name: C16-C18 and C18 unsaturated alkyl carboxylic acid amide diethanol and SDA Reporting Number: 11-024-00.

Description of key information
Additional information
Although the log Kow of amides, C16-18(even numbered) and C18-unsatd., N,N-bis(hydroxyethyl) ranges from 5.45 to 6.05, a calculated weighted mean BCF value of 81 L/kg w/w indicates no significant bioaccumulation potential. This assumption is supported by the available toxic kinetics data, according to which the substance is expected not to significantly bioaccumulate based on rapid and effective metabolism by P450 enzymes into innocuous polar metabolites which are then rapidly excreted (primarily) in urine.
Based on these data and considering its ready biodegradability, it can be assumed that amides, C16-18(even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) has a low bioaccumulation potential.
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.
