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 both the cosmetic[5] and oral industries.[6][7]

Aluminium lactate is also used as a precursor for sol–gel synthesis of alumina-based glasses.[8]
