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).
