Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is inorganic
- the study does not need to be conducted because the substance decomposes
- Endpoint:
- partition coefficient
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2019-06-25
- 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
- Justification for type of information:
- 1. SOFTWARE
OECD QSAR Toolbox v4.3.1
2. MODEL (incl. version number)
KOWWIN (EPIWIN v4.1)
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
[Mg+2].[O-]Cl(=O)(=O)=O.[O-]Cl(=O)(=O)=O
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
Please refer to 'Attached justification'
5. APPLICABILITY DOMAIN
Please refer to 'Attached justification' - Guideline:
- other: ECHA Guidance R.6
- Principles of method if other than guideline:
- - Software tool(s) used including version: OECD QSAR Toolbox v4.3.1
- Model(s) used: KOWWIN (EPIWIN v4.1)
- Model description: see field 'Justification for non-standard information' and 'Attached justification'
- Justification of QSAR prediction: see field 'Justification for type of information' and 'Attached justification' - Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- [Mg+2].[O-]Cl(=O)(=O)=O.[O-]Cl(=O)(=O)=O
- Type:
- log Pow
- Partition coefficient:
- -6.53
- Temp.:
- 25 °C
- Remarks on result:
- other: pH not specified in QSAR model
- Conclusions:
- The logKow was determined to be -6.53 by the model KOWWIN (EPIWIN v4.1) implemented in the OECD QSAR Toolbox v4.3.1.
- Executive summary:
The logKow was determined to be -6.53 by the model KOWWIN (EPIWIN v4.1) implemented in the OECD QSAR Toolbox v4.3.1.

Description of key information
logKow = -6.53 (KOWWIN (EPIWIN v4.1) implemented in the OECD QSAR Toolbox v4.3.1)
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -6.53
- at the temperature of:
- 25 °C
Additional information
The study does not need to be conducted because magnesium perchlorate is inorganic. Furthermore the study does not need to be conducted because magnesium perchlorate decomposes. Therefore, a calculated value for log P as well as details of the calculation method are provided.
The logKow of Magnesium perchlorate was determined to be -6.53 by the model KOWWIN (EPIWIN v4.1) implemented in the OECD QSAR Toolbox v4.3.1.
