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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- EPI Suite
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- THis was an evaluation of the partition coefficient based on data in EPI Suite.
- GLP compliance:
- no
- Type of method:
- other: estimation based on SMILES using EPI Suite
- Partition coefficient type:
- octanol-water
- Type:
- log Pow
- Partition coefficient:
- < 2.76
- Temp.:
- 25 °C
- pH:
- >= 10 - <= 12
- Remarks on result:
- not measured/tested
- Conclusions:
- Partition coefficient log Pow for the solid substance is estimated to be -2.76
- Endpoint:
- partition coefficient
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance has a high surface activity

Description of key information
The end point has been waived based on the fact that it has high surface activity - see surface tension result and substance is an amphoteric surfactant. It is readily soluble in water being manufactured and marketed as a 50% solution in water.
The estimated Partition coefficient log Pow for the solid substance is estimated to be -2.76 using EPI Suite and SMILES notation for the solid substance.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -2.76
- at the temperature of:
- 25 °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.
