Description of key information

Additional information

The adsorption/desorption study was not conducted as the substance dissociates and degrades to carbon dioxide, water and inorganic aluminium species. At environmental pH (ca 7.0) aluminium will mainly be in the form of insoluble hydrated oxide species which, although likely to absorb onto soil, are not expected to be scientifically relevant as they are naturally abundant in the environment.

In realistic use scenarios, the thickeners will be contained in a base oil matrix, with the formulated greases specifically designed to minimise the leaching of the thickener and, given the very low solubility of the substance in water, the concentrations of the substance which would be available for adsorption are limited.
