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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
Both the source and the target substance have Sn2+ as constituent.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
Purity not relevant since no info is available. Hence, 100 % purity assumed.
3. ANALOGUE APPROACH JUSTIFICATION
SnCl2 and SnS have Sn2+ ions in solution.
4. DATA MATRIX
not relevant since no toxic properties are relevant. - Reason / purpose for cross-reference:
- read-across source
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- -2.47
- Remarks on result:
- other: no info on pH and temperature
- Conclusions:
- log Pow: -2.47
- Endpoint:
- partition coefficient
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is inorganic

Description of key information
In accordance with column 2 of REACH Regulation (EC) No 1907/2006 Annex VII section 7.8, the study is not required since tin sulfide is inorganic. Literature data report an LogPow of -2.47 for SnCl2. This information is considered relevant for SnS as well. The results indicate that bioaccumulation is not a concern for the registered substance.Key value for chemical safety assessment
- Log Kow (Log Pow):
- -2.47
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.
