Aluminium lactate is a chemical compound, a salt of aluminium and lactic acid with the formula Al(C₃H₅O₃)₃. ^{[1] [2]}

Synthesis

Aluminium lactate is obtained by precipitating a solution of the barium salt by aluminium sulfate. ^[3]

Physical properties

Aluminium lactate appears as a white powder which is soluble in water.

Use

Aluminium lactate is used as a mordant. ^[4]

It is suitable for use in the cosmetic industry as a keratolytic agent ^[5] or antiperspirant ^[6] , and in the oral industry. ^{[7] [8]}

Aluminium lactate is also used as a precursor for sol–gel synthesis of alumina-based glasses. ^[9]
