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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
1.2 g/cm³ (ISO 1183 -1 / OECD TG 109 / EU method A.3); read-across: C8 -18 AAPB, C12 AAPB, Formamidopropylbetaine
Key value for chemical safety assessment
- Relative density at 20C:
- 1.2
Additional information
No experimental data are available for the substance itself. However, reliable data are available for the closely related source substances C8 -18 AAPB, C12 AAPB and Formamidopropylbetaine.
The relative density D (4/20) of C8 -18 AAPB was determined to be 1.15 (study according to ISO 1183 -1).
The relative density D (4/20) of C12 AAPB was determined to be 1.20 (study according to ISO 1183 -1).
The density of Formamidopropylbetaine is 1.14 g/cm³ (1.14E3 kg/m³) at 20°C (OECD TG 109 / EU method A.3).
The density of the source substances is in the same range (1.14 to 1.2 g/cm³). Based on the available data, it can be assumed that the differences chain length distribution of the fatty acid chain have no or at the most a minor impact on density. Thus, a similar density can be assumed for the target substance Undecylenamidopropyl Betaine.
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.
