Chemistry

Aluminium monoacetate is prepared by the diformate, Al(OH)(O₂CH)₂ • H₂O, crystallizing from a concentrated solutions of newly precipitated Al(OH)₃ in formic acid. With an excess of the acid, Al(O₂CH)₃ • 3H₂O crystallizes.[2]

Reaction in which Aluminium monoacetate is involved: Al(OH)(CH₃COO)₂ + H₂O → Al(OH)₂(CH₃COO) + CH₃COOH[3]

Uses

Aluminium monoacetate is a dermatological agent used as an antiseptic and astringent.[4] It is used as an antiseptic to reduce the possibility of infection in minor wounds, cuts, and burns. Specifically, it treats itching, stinging of the infected skin, inflammation, and it promotes healing. It also can be used as a topical astringent to help shrink the body's tissues when applied to the skin as it acts as a protective layer on irritated and inflamed skin.
