- Key result
- Water solubility:
- 1.31 g/L
- Conc. based on:
- test mat.
- Temp.:
- 21 °C
- pH:
- ca. 5
- Conclusions:
- Interpretation of results (migrated information): soluble (1000-10000 mg/L)
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), which as been determined to be: 1.31g/L at 21.0 °C ± 0.5 °C. According to REACH regulation, the substance is considered as soluble. - Executive summary:
The water solubility of 1,3-Propanediamine,N-tallow-,diacetate has been determined according to OECD 115 and following GLP. In the test conditions (T° = 21°C), the CMC has been determined to be 1.31 g/L.
Reference
Description of key information
The registered substance forms micelles in water, it is considered as a surfactant. Therefore, the water solubility is expressed as the critical micelle concentration (CMC), which as been determined to be: 1.31g/L at 21.0 °C ± 0.5 °C -TG OECD 115).
Key value for chemical safety assessment
- Water solubility:
- 1.31 g/L
- at the temperature of:
- 21 °C
Additional information
According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance page 79", the critical micelle concentration (CMC) can be view as the solubility limit for surfactants. The registered substance has a surface tension of 43 mN/m at 20°C, according the TG OECD 115 and GLP it tensio-active properties are therefore confirmed (<60 mN/m).
1,3-Propanediamine,N-tallow-,diacetate forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 1.31g/L at 21.0 °C ± 0.5 °C.
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).
