- Conclusions:
- The substance, as anhydrous or hydrated form, is more dense than water.
- Executive summary:
A reference handbook, also cited in a reference database provides a density value of 1.61 for the anhydrous form.
A value of 1.69 is also cited for the octadecahydrate form.
- Endpoint:
- density, other
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Justification for type of information:
- The test substance is aluminium sulphate basic, of formula Al2 (OH)0.16 (SO4)2.92, and not pure aluminium sulphate Al2 (SO4)3; however, according to the notifier, limited basicity may occur in the technical substance. Therefore, the chemical similarity (only 0.8% OH) is considered sufficient for supporting data on the hydrated form, the reference substance for the REACh registration dossier being the anhydrous form.
- Reason / purpose for cross-reference:
- read-across source
- Executive summary:
From analogue, the density of the 15 - 16 H2O hydrated form is expected to be ca 1.8 g/cm3.

- Remarks:
- This study has been performed according to OECD and EC guidelines and according to GLP principles. Test substance is adequately characterised. Therefore full validation applies.

- Conclusions:
- The test substance is more dense than water.
- Executive summary:
The density of aluminium sulphate basic hydrated was investigated according to OECD/EC guidelines, gas comparison method. After calibration, measurements were performed in duplicate, and the mean value of 1.79 g/cm3 was retained for true (not apparent/bulk) density.
Referenceopen allclose all
Test 1: 1.794 g/cm3
Test 2: 1.790 g/cm3
Measurements were within accuracy limits, therefore the mean value was retained.
Description of key information
Aluminium sulphate, as anhydrous or hydrated form, is much more dense than water.
Results between 1.61 and 2.71 are reported (grade-dependent).
Key value for chemical safety assessment
- Relative density at 20C:
- 2.71
Additional information
Three reliable literature sources are provided for the reference substance (anhydrous form), and are considered as key data. The value of 2.71 g/cm3 was also found in numerous commonly used handbooks or databases, despite not peer reviewed. Therefore this value will be retained as key value for purpose of CSA.
One of the above key source, as well as supporting information on the 18 H2O and on analogue in an experimental report provide lower values, ranging between 1.61 and 1.79; however, it is sometimes not specified if the result relates to true or apparent (bulk) density. Moreover, different cristallisation forms may lead to a different density.
