Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Relative density of calcium thiosulphate hexahydrate: 1.87 at approx. 20 °C.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.87
Additional information
For the evaluation of this endpoint data from one handbook (CRC handbook) were used as key information. Handbook data considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance". Useful reference books and data compliations containing peer reviewed physico-chemical data include the CRC Handbook of Chemistry and Physics.
Data from this handbook indicate that calcium thiosulfate hexahydrate has a density of 1.87 g/cm³. According to the reference, the density values can be assumed to refer to temperatures near room temperature. For this reason 20 °C was filled in as temperature.
The relative density was calculated from the value in the handbook. The value was divided by the relative density of water at 4 °C (1.000).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.
