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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 200-853-0 | CAS number: 75-24-1
Partition coefficient
Administrative data
- Endpoint:
- partition coefficient
- Type of information:
- (Q)SAR
- Remarks:
- QSAR provided for the purposes of Technical Completeness Check completion. As discussed in the waiver statement, this substance decomposes dangerously in the presence of moisture or air and will not be available for assessment.
- Adequacy of study:
- key study
- Study period:
- January 2022
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Remarks:
- Calculated for the purposes of technical completeness only; the substance will not be available once exposed to water or air.
- Justification for type of information:
- Calculated for the purposes of technical completeness in order to fulfil ECHA's request. In use the substance would never be available for measurement as the substance will rapidly transform to aluminium oxides / hydroxides in the environment in the presence of water or air. Please refer to the waiver statement for further information.

Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- 1.97
- Remarks on result:
- other: QSAR derivation using US EPA KOWWIN v1.68
- Details on results:
- Calculated for the purposes of technical completeness; in use the substance would never be available for measurement as the substance will rapidly transform to aluminium oxide and aluminium hydroxide in the environment in the presence of water or air.
Applicant's summary and conclusion
- Conclusions:
- Conducted to fufill requirements of TCC only. Please refer to waiver statement for further information. The calculated value for log Kow is 1.97.
- Executive summary:
Calculated for the purposes of technical completeness; in use the substance would never be available for measurement as the substance will rapidly transform to aluminium oxide and aluminium hydroxide in the environment in the presence of water or air.
