Infobox references

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]
