- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 1183-1
- Principles of method if other than guideline:
- Acetone was used as solvent as C12 AAPB was visually completely soluble in water. Due to the volatility of acetone an ultrasonic bath instead of vacuum was used to remove air bubbles.
- GLP compliance:
- not specified
- Type of method:

- Density:
- 1.2 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density D (4/20) of C12 AAPB was determined to be 1.20 using a Hubbard pycnometer.
- Executive summary:
The relative density of C12 AAPB was determined in a study conducted according to ISO 1183 -1. In deviation from guideline toluene was used as solvent as C12 AAPB was visually completely soluble in water. A relative density D (4/20) of 1.20 was determined using a Hubbard pycnometer.

- Conclusions:
- The density of FORMAMIDOPROPYLBETAINE is 1.14 g/cm³ (1.14E3 kg/m³). The D20 4 is 1.14.
- Executive summary:
The determination of the density (liquid) of FORMAMIDOPROPYLBETAINE was performed in accordance with the EEC-Directive 92/69 EEC, A.3 "Relative density" (1992) and OECD guideline no. 109 "Density of liquids and solids" (1995). A glass pycnometer with a nominal volume of 10 mL was used. The temperature of measurement was 20.0 °C.
The density of FORMAMIDOPROPYLBETAINE is 1.14 g/cm³ (1.14E3 kg/m³). The D20 4 is 1.14.

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 C8-10 Alkylamidopropyl betaine.
