Further, the high degree of neutralization of the HCl results in minimal impact on treated water pH when compared to other aluminium and iron salts.
Aluminium chlorohydrate is also used as a coagulant in water and wastewater treatment processes to remove dissolved organic matter and colloidal particles present in suspension.
[6] The International Journal of Fertility and Women's Medicine found no evidence that certain chemicals used in underarm cosmetics increase the risk of breast cancer.
[6] However, there is continued concern over the use of aluminium chlorohydrate in cosmetics as the risk of toxic build up over time has not been ruled out.
However, techniques such as gel permeation chromatography, X-ray crystallography and 27Al-NMR have been used in research by various groups including that of Nazar[10] and Laden[11] to show that the material is based on Al13 units with a Keggin ion structure and that this base unit then undergoes complex transformations to form larger poly-aluminum complexes.
