Question:

Does the amount of aluminum found in deodorants make it dry faster or slower?

Does the amount of aluminum found in deodorants make it dry faster or slower?

Answer:

Aluminium zirconium tetrachlorohydrex gly, a common antiperspirant, Aluminum compounds or aluminum salts, such as aluminum oxide (Al2O3), are key ingredients in almost every antiperspirant. They are powerful astringents that close pores, THe aluminum is basically there to stop perspiration.They do not have an effect n how long the application take to dry. Deodorants work by keeping bacteria from growing that use the sweat for food long with skin cells that slough off.
Like any chemical reaction quantity would matter. Aluminum Chloride is one of several active ingredients. It works by doing two things. The first is it is an astrigent which causes the sweat glands to shrink or close up. The second is that it reacts with sweat to form a gell like substance that plugs up the pores. The combined effect is to stop sweating. The two effects are temporary and the pores eventually open up and clear themselves out. These two drying effects of aluminum chloride are fast acting and work upon application. So to answer your question i would consider aluminum as a means of making a deoderant dry faster by stopping the sweat from leaving the pores.
Al does not have the ability to retain heat for very long. Therefore theroretically, the greater the amount of Al the faster the substance would dry.
