Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 CMC is determined to 3.5 mg/L at pH 7. The surface tension at 0.2 g/L is determined to 30 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 30
- in mN/m at 20°C and concentration in mg/L:
- 200
Additional information
Read across. Structural similarities within the Primary Fatty Amine Ethoxylated (PFAEO) category (the substances have almost the same carbon chain distribution). Although the hydrogenated substance is more saturated, this will not have a significant effect on the micelle formation in this case. Furthermore, the molecular weights are in the same range and the distribution between primary, secondary and tertiary nitrogen is similar, that is, consist of tertiary nitrogen.
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.
