Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-10-20
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", the critical micelle concentration (CMC) can be view as the solubility limit. The CMC has been determined according to standardized method, no GLP compliance.
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- yes
- Remarks:
- pH adjusted to 7
- Principles of method if other than guideline:
- According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", the critical micelle concentration (CMC) can be view as the solubility limit. The cmc has been determined using the harmonised ring method
- GLP compliance:
- no
- Type of method:
- other: The cmc has been determined using the harmonised ring method
- Specific details on test material used for the study:
- Substance name: Bis (2-hydroxyethyl) hydrogenated tallow alkylamine
CAS No: 90367-28-5
Batch Number: S-001017 - Key result
- Water solubility:
- 3.5 mg/L
- Temp.:
- 23 °C
- pH:
- 7
- Details on results:
- Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 3.5 mg/L (pH 7, 23°C).
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 3.5 mg/L (pH 7, 23°C). - Executive summary:
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 3.5 mg/L (pH 7, 23°C).
Reference
The CMC is determined from the CMC curve by solving the two equations. The CMC for Ethomeen HT/12 at pH 7 is determined to 3.5 mg/L. The operating temperature is room
temperature, in this case 23°C. Also, the surface tension at 0.2 g/L solution has been determined at pH 7 to 30 mN/m.
Description of key information
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 3.5 mg/L (pH 7, 23°C).
Key value for chemical safety assessment
- Water solubility:
- 3.5 mg/L
- at the temperature of:
- 23 °C
Additional information
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.
