System and method for manufacturing aluminum chlorohydrate

A method of batch manufacturing aluminum chlorohydrate (ACH) utilizing a reactor tank comprising:

• conducting two consecutive batch manufacturing processes, each batch manufacturing process producing aluminum chlorohydrate (ACH) by reacting solid-state aluminum metal pieces with an acid source in a reactor tank;
• proximate the end of a first of the two batch manufacturing processes, after the aluminum chlorohydrate (ACH) being produced in that batch has reached a predetermined basicity level, withdrawing a majority of the produced aluminum chlorohydrate (ACH) from the reactor tank but retaining a heel-portion of the produced aluminum chlorohydrate (ACH) in the reactor tank, wherein the heel-portion comprises a sufficient amount of the produced aluminum chlorohydrate (ACH) to submerge therein a majority of unreacted solid-state aluminum metal pieces retained in the reactor tank at the time that produced aluminum chlorohydrate (ACH) is withdrawn from the reactor tank;
• and
• maintaining a substantial entirety of the retained, unreacted solid-state aluminum metal pieces in the reactor tank submerged in produced aluminum chlorohydrate (ACH) until a second of the two consecutive batch manufacturing processes is initiated and thereby substantially preventing air-exposure to the unreacted solid-state aluminum metal pieces between the first and second of the two consecutive batch manufacturing processes being conducted.
