Chemical formula of aluminum acetate

Aluminum acetate is a chemical compound and is a salt which can be produced by the reaction of aluminum hydroxide and acetic acid. The compound formula for aluminum acetate is Al(C2H3O2)3.

Molecular formula: C6H9AlO6

Three such salts exist:

  1. Neutral Aluminum triacetate, Al(C2H3O2)3
  2. Basic Aluminum diacetate, HOAl(C2H3O2)2
  3. Basic Aluminum monoacetate, (HO)2AlC2H3O2


The triacetate forms when aluminum sulfate is mixed with barium acetate. Another synthetic method is by bringing together aluminum hydroxide, acetic anhydride and glacial acetic acid in water, forming the basic aluminum monoacetate

The diacetate is prepared in a reaction of sodium aluminate (NaAlO2) with acetic acid.


The diacetate is used as an antiseptic. The aluminum acetate compound can be used medicinally to treat infections in the outer ear canal. It is used in the name brand drug Domeboro, which contains acetic acid/aluminum acetate.[1] This medication kills the infectious bacteria and fungus as well as drying out the ear canal.

Since it acts as a drying agent, it can also be used in the treatment of severe rashes, such as poison ivy, poison oak, and poison sumac.[2] It can be found under the name brand TriCalm for the treatment of itching associated with rashes, hives, bug bites, and allergic reactions.[3]
