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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 256-275-4 | CAS number: 46728-75-0
Partition coefficient
Administrative data
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- January 24, 1984 thru September 28, 1984
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Justification for type of information:
- Weight of Evidence: The measured value is reported without adequate documentation to judge its reliability. However, when coupled with a read-across value and an estimated (QSAR) value, its reliability is enhanced.

Applicant's summary and conclusion
- Conclusions:
- The measured octanol-water partition coefficient (Log Pow) of the test substance was determined to be <0.04.
- Executive summary:
In a non-GLP study conducted using an HPLC method believed to be equivalent to OECD 117, the octanol-water partition coefficient (Low Pow) was determined to be <0.04.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
