Aluminium chlorohydrate is a group of salts having the general formula Al_nCl_(3n-m)(OH)_m. It is used in deodorants and antiperspirants and as a flocculant in water purification. A magnified crystal of a salt (halite/sodium chloride) In chemistry, a salt is any ionic compound composed of positively charged cations and negatively charged anions so that the product is neutral and without a net charge. ... General Name, Symbol, Number aluminium, Al, 13 Chemical series poor metals Group, Period, Block 13, 3, p Appearance silvery Atomic mass 26. ... The chloride ion is formed when the element chlorine picks up one electron to form an anion (negatively-charged ion) Cl−. The salts of hydrochloric acid HCl contain chloride ions and are also called chlorides. ... Hydroxide is a polyatomic ion consisting of oxygen and hydrogen: OH− It has a charge of −1. ... Stick deodorant Roll-on deodorant Deodorants are cosmetic substances applied to the body, most frequently the armpits, to reduce the body odor caused by the bacterial breakdown of perspiration. ... Deodorants are cosmetic substances applied to the body, most frequently the armpits, to reduce the odor of perspiration. ... Flocculation refers to a process where a solute comes out of solution in the form of floc or flakes. The term is also used to refer to the process by which fine particulates are caused to clump together into floc. ... Water purification is the removal of contaminants from raw water to produce drinking water that is pure enough for human consumption. ...

In water purification, where it is usually called polyaluminium chloride, this compound is preferred in some cases because the pH value can be varied according to the exact values chosen for the subscripts _n and _m in the pattern formula. Although many variations are used, an especially important combination is Al₁₂Cl₁₂(OH)₂₄. The actual pH correlates to the formula m/(3n). pH is a measure of the acidity of a solution, in terms of activity of hydrogen ions (H+). For dilute solutions, however, it is convenient to substitute the activity of the hydrogen ions with the molarity (mol/L) of the hydrogen ions (however, this is not necessarily accurate at higher...

The variation most commonly used in deodorants and antiperspirants is Al₂Cl(OH)₅. There is no scientific evidence supporting widespread rumors that aluminum salts in deodorants can cause Alzheimer's disease or breast cancer. Breast cancer is cancer of breast tissue. ...
