Aluminium chlorohydrate is an inorganic compound that is used as an active ingredient in many antiperspirant and astringent products. It works by forming a temporary plug within the sweat duct, reducing the amount of sweat produced by the body. It is also used as a flocculant in water purification processes, to remove suspended particles from the water.
Aluminium chlorohydrate is a group of water-soluble aluminum salts, often referred to as an alum, commonly used as an antiperspirant and a coagulant in water purification
As an antiperspirant, aluminium chlorohydrate works by temporarily blocking sweat glands, reducing the amount of sweat reaching the skin's surface. This helps to control sweating and prevent body odor. It is found in many over-the-counter deodorants and antiperspirants, typically at concentrations of up to 25%.
In water purification, aluminium chlorohydrate is used as a flocculant to remove suspended particles from the water. It works by causing the particles to clump together, making them easier to settle out or filter out of the water.
Aluminium chlorohydrate is generally considered safe for most people when used as directed. However, some people may experience skin irritation, such as itching, burning, or stinging, at the site of application. In rare cases, aluminium chlorohydrate may also interfere with the absorption of other medications taken by mouth.
It is important to note that aluminium chlorohydrate has been the subject of some controversy in recent years, with some people concerned about potential links to health problems such as breast cancer and Alzheimer's disease. However, the scientific evidence on these potential links is inconclusive, and most major health organizations consider aluminium chlorohydrate to be safe for use in antiperspirants
