Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- other: OECD guideline 115
- Version / remarks:
- CMC measurement Du Noûy ring method
- Principles of method if other than guideline:
- The experiment was performed by mixing the substance with water in different ratio. The analyzed
substance all formed cloudy/hazy emulsions at every concentration tested; hence the solubility is very
low (below 0.1%). To more accurately be able to determine the low water solubility, CMC analysis was
employed. - GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- other: Determination of CMC of surface active substance
- Water solubility:
- 190 mg/L
- Temp.:
- 20 °C
- pH:
- 6
- Conclusions:
- The water solubiity of the substance is 190 mg/L
- Executive summary:
The water solubility was determined as the Critical Micelle Concentration to be 190mg/L at pH 6 and 20 °C.
Reference
Description of key information
The substance has a water solubility of 190 mg/L. The Ctitical Micelle Concentration CMC is used as a measure of the solubility of the substance.
Key value for chemical safety assessment
- Water solubility:
- 190 mg/L
- at the temperature of:
- 20 °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.
