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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 922-520-5 | CAS number: -
Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- calculation (if not (Q)SAR)
- 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: Calculation of solubility ratio octanol/water
- Principles of method if other than guideline:
- Water solubility was determined by determination of Critical Micelle Concentration, since the substance is surface active. Octanol solubility has been determined by visual inspection. The ratio of solubilities was then calculated.
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- estimation method (solubility ratio)
- Partition coefficient type:
- octanol-water
- Analytical method:
- other: visual inspection
- Type:
- log Pow
- Partition coefficient:
- 3.2
- Temp.:
- 20 °C
- pH:
- 6
- Conclusions:
- The log Kow value was determined to be 3.2 by calculting the solubility ratio in water and octanol.
- Executive summary:
The log Kow value was determined to be 3.2 by calculating the solubility ratio in water and octanol.
Reference
Description of key information
The log Kow was determined by calculation of the solubility ratio of the substance, since this is a surface active agent.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 3.2
- 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.
