So today I come to you yet again with another question: ever wondered
what your deodorant does to stop you from sweating? Basically it stops bacteria
from forming and in some cases even prevent the sweat glands from forming
sweat. This is done by using antiperspirants. Depending on the type of product,
antiperspirants usually contain salts to actually reduce the flow of sweat from
the skin. These salts work by dissolving in sweat and leaving a thin coating of
gel over the sweat glands. This coating reduces the amount of sweat on the skin
for a number of hours after the antiperspirant is applied. The most common of
these salts is aluminium chlorohydrate.
Al2Cl(OH)5 is one of the most common active ingredients in
commercial antiperspirants and is also often used as a flocculant in water purification stations.
It belongs to a specific group of aluminium slats and is commercially manufactured
by reacting aluminium with hydrochloric
acid.
Although it's the least irritating of the aluminum salts, there have
still been concerns from some researchers calming that it can cause breast
cancer and other damages as the compound is capable of passing through the
blood-brain barrier. However many studies have strongly defended the safety of
the product.
