Formula

A12(OH)2(C2H3O2)4.

Derivation

The salt, Acetate of Alumina, is obtained by the direct combination of hydrated alumina with acetic acid, or by reaction between sulphate of alumina and acetate of lead. The solution, when properly prepared, is a clear fluid, of a sharp, sweetish, astringent taste, and a distinct odor of acetic acid. When it is evaporated, there is deposited light, fragile, glossy scales, which are perfectly soluble in water, and not readily affected by the atmosphere.

Medical Properties And Action

It is disinfectant and antiseptic. In maximum doses it produces an unpleasant sensation of warmth and fullness in the stomach, and at the same time, vertigo and confusion of the senses, which may continue for several hours.

Therapeutic Uses

Acetate of alumina is rarely employed internally, and only for zymotic and contagious diseases. It is generally used externally, and is a very effectual remedy in the treatment of wounds, preventing pyemia in suppurating wounds and ulcers. It is also applied in parasitic skin affections, as an injection in gonorrhoea, and for the destruction of animalculae in putrescent fluids. As a surgical dressing, it is used by keeping the wound saturated with a solution of moderate strength, or by irrigation. A concentrated solution will preserve anatomical subjects for a considerable time.

Dose

Of acetate of alumina, gtt. xx to gtt. 60 of the solution.

Dental Uses

Acetate of alumina is useful in dental practice, as an antiseptic and disinfectant in cancrum oris, ulcers of the mouth, suppurating wounds of mucous membrane, pyorrhoea alveolaris, alveolar abscess, etc. A very weak solution has been employed as a mouth-wash for offensive breath depending on scrofulous ulcerations, aphthae, caries of the teeth, or the wearing of artificial teeth.
