Chemistry

Aluminium monoacetate is prepared from the reaction between Al(OH)₃ and dilute aqueous acetic acid.^[1] It is also formed from the successive hydrolysis of aluminium triacetate.^[2][3]

Al(CH₃COO)₃ + H₂O → Al(OH)(CH₃COO)₂ + CH₃COOH

Al(OH)(CH₃COO)₂ + H₂O → Al(OH)₂(CH₃COO) + CH₃COOH

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.
