According to The Manual, antiperspirants in particular are the main cause of yellow stains, because the active ingredient in many antiperspirants is aluminum.

According to Natural News, some aluminum compounds found in underarm products are aluminum chlorohydrate, aluminum chloride and aluminum zirconium. However, The Manual does note that aluminum chlorohydrate is deemed the least harmful agent to clothing.
