not considered to bioaccumulate. The substance has very low water
solubility and is readily biodegradable therefore, in the environment
the substance will convert into inorganic aluminium species plus small
amounts of fatty acids and benzoic acid as a result of dissociation. The
fatty acids are natural substances with a long history of safe use in
foods and benzoic acid has a calculated BCF of 7.9 (Veith et al 1987)
and is therefore not expected to bioaccumulate in the aquatic
is expected to have a low potential for bioaccumulation, with BCF of
around 36 at pH 7.2 in fresh
water fish (Cleveland
et al 1991).
the availability of aluminium in the aqueous environment is very
dependent on pH. Soluble aluminium species are only readily available to
aquatic species at pH < 4. At neutral pH aluminium will be in the form
of essentially insoluble hydrated oxide species, which reduces their
bioavailability by direct
realistic use scenarios, the aluminium thickener will be contained in
base oil, with the formulated greases specifically designed to minimise
the leaching of the thickener. Therefore, during use, the concentrations
of the substance which would be bioavailable are further limited.
