Description of key information

Silicic acid, aluminium magnesium sodium salt is an inorganic solid insoluble in n-octanol. Due to its inherent chemico-physical properties, bioaccumulation is not to be expected. Its log Kow is -1.5 (calcualted), and therefore smaller than 3.

Besides, as the substance is moderately soluble, low concentrations are expected in the aquatic compartment. Low quantities which might be taken up are considered to be not bioavailable as it is known that no toxicologically relevant absorption of Al occurs, whereas absorbed Si levels are known to be rapidly excreted in urine and faeces. Na and Mg are essential minerals. Thus, silicic acid, aluminium magnesium sodium salt contains no bioaccumulation potential.
