 Molecular size is the main difference between Potassium alum (Aluminium potassium sulfate dodecahydrate) and the salts Aluminium chloride and Aluminium chlorohydrate which are commonly used in antiperspirants.

Potassium Alum vs Aluminium chloride / chlorohydrate

Aluminium chloride and Aluminium chlorohydrate have a small molecular size and work as antiperspirants by entering sweat ducts and reacting with amino acids and peptides to form a gel. This gel then plugs the sweat duct and prevents sweating. 

The aluminium in Potassium alum that we use is bonded into a much larger molecule – one that is physically too large to be absorbed through the skin.

Instead of forming a gel, thereby preventing perspiration, Potassium Alum sits on the surface of the skin where it prevents the bacteria responsible for causing sweaty odours from multiplying.
