Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 May 2010- 5 August 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study

This study has been performed according to OECD and EC guidelines and according to GLP principles. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Deviations:
no

Test 1: 1.941 g/cm3

Test 2: 1.952 g/cm3

The individual measurements were obtained with an accuracy of < 0.02 g/cm3. According to the guideline, the density of the test substance is given as the mean value.

Conclusions:
The test substance is more dense than water.
Executive summary:

The density of dialuminium chloride pentahydroxide was investigated according to OECD/EC guidelines, gas comparison method. After calibration, measurements were performed in duplicate, and the mean value of 1.95 g/cm3 was retained for true (not apparent/bulk) density.

Description of key information

The substance is more dense than water (true density of powder).

Key value for chemical safety assessment

Relative density at 20C:
1.95

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study, and the result is retained as key data for purpose of CSA.
