Aluminium acetotartrate (or ALSOL) is an organic acid, astringent, and disinfectant. It is the aluminium salt of acetic acid and tartaric acid.[1][2]
Aluminium acetotartrate occurs as colorless or yellowish crystals, freely but exceedingly slowly soluble in water and insoluble in alcohol and ether.[1]
Aluminium acetotartrate is employed in 0.5–2% solutions as a nasal douche in affections of the respiratory tract, in 1–3% solutions as a substitute for solution of aluminium acetate, in concentrated solution as a lotion in frostbite and balanitis, and as a snuff with boric acid in atrophic rhinitis.[1] It is also used as an antiseptic vulnerary ointment cream.[1]
