Abstract
A system and method for producing commercial strength solutions of aluminum chlorohydrate are provided. The method includes providing aluminum chlorohydrate monohydrate (ACHMH) powder, heating water to at least 120° F. and less than 200° F., and dissolving at least a portion of the ACHMH powder into the heated water to form the solution of aluminum chlorohydrate. The produced solution of aluminum chlorohydrate from the ACHMH powder has an aluminum oxide concentration ranging from about 18 wt % to about 27 wt %, has a basicity ranging from greater than 74% and less than 83%, and has a freezing point ranging from about 10° F. to about 16° F. The solution may also have an iron content of between about 0 to about 70 ppm as Fe.
Claims18
A method of forming a solution of aluminum chlorohydrate the method comprising:
- providing aluminum chlorohydrate monohydrate powder having a composition of
- Al2(OH)aCl(6-a)—XH2O
- where
- a=4.4 to 5 and X=0 to 1.7;
- heating water to at least 120° F. and less than 200° F.;
- and
- dissolving at least a portion of the aluminum chlorohydrate monohydrate powder into the heated water to form the solution of aluminum chlorohydrate wherein the solution remains gel-free.
A solution of aluminum chlorohydrate made from chlorohydrate monohydrate powder having a composition of Al2(OH)aCl(6-a)—XH2O
- where a=4.4 to 5 and X=0 to 1.7, the solution comprising:
- an aluminum oxide concentration ranging from about 18 wt % to about 27 wt %, wherein the solution has a basicity ranging from greater than 74% and less than 83%, and a freezing point ranging from about 10° F. to about 16° F.
