Aluminium citrate is a chemical compound with the chemical formula AlC
6H
5O
7. This white, crystalline salt is produced by mixing aluminium chloride hexahydrate and citric acid.[1]
Aluminium citrate can be used as a crosslinker for many polymers in the oil industry.[2] It is also used as an antiperspirant.
Aluminium citrate takes up about 8% of aluminium in blood[3] due to the ability of Al3+ ions to replace Ca2+ from calcium citrate and is known to cause chronic renal failure because it causes an increase of phosphorus in the kidneys.[4] It has been suspected to cause Alzheimer's disease but more evidence is needed.[5] This compound can also have some positive effects on humans such as preventing silicosis.[6] When ingested, 80% of the compound is excreted through the body through urine and the rest comes out slower.[3]
Aluminium citrate can form complexes such as ammonium aluminium citrate ((NH4)4Al3C6H4O7(OH)(H2O)), which can be created by mixing aluminium nitrate nonahydrate, citric acid, and ammonium hydroxide.[7]
