Determination 1: 1.360 g/cm3

Determination 2: 1.360 g/cm3

The individual measurements were obtained with an accuracy of < 0.01 g/cm3. According to the guideline, the density of the test substance is given as the mean value.

Conclusions:
The solution is more dense than water.
Executive summary:

The density of aluminium chloride basic (as aqueous solution) was investigated according to OECD/EC guidelines, pycnometer method. Two assays were performed, and the mean value of 1.360 g/cm3 was retained. The relative density towards water at 4°C was calculated to be 1.36.

Description of key information

The aqueous solution as manufactured is more dense than water.

Key value for chemical safety assessment

Relative density at 20C:
1.36

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.

As an UVCB, it should be noted that the value of the parameter may show some variations.
