Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- yes (incl. QA statement)
- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 2.22
- Temp.:
- 20 °C
- Conclusions:
- The relative density of calcium dihydroxide (Precal 50S) at the test temperature compared to water at 4 °C (D 20/4) was found to be 2.22.
- Executive summary:
The density of Precal 50S (calcium dihydroxide (hydrated lime)) was tested by the pycnometer method and in accordance with OECD guideline 109. The relative density of Precal 50S was found to be 2.22.

Description of key information
The relative density of calcium dihydroxide (hydrated lime) measured in accordance with OECD TG 109 using the pycnometer method is 2.22.
Key value for chemical safety assessment
- Relative density at 20C:
- 2.22
Additional information
The relative density of calcium dihydroxide (hydrated lime; purity = 98.2%) measured in accordance with OECD TG 109 using the pycnometer method is 2.22.
The relative density of calcium carbonate, based on a weight of evidence using data from several peer reviewed handbooks, is 2.7. Thus it may be expected that grades of calcium dihydroxide with up to 35% calcium carbonate will have a relative density in the range of 2.2 - 2.7.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
