Aqueous AlCl3 solutions are often used as very effective antiperspirants at 10-20% concentration, but these solutions are not acidic to my knowledge.
My understanding is that adding AlCl3 to water produces HCl and Aluminum Hydroxide (?). The ingredients on some of these bottles simply state AlCl3,
whereas other bottles state some variation of Aluminum Hydroxide Hydrochloride.
I want to make my own bottle for personal usage since it is cheaper than buying a small premixed bottle which seem to be sold for $50(!!). Stores sell
roll-on mini bottles for $5, but I want something I can use in a spray-bottle.
I've got plenty of Aluminum Chloride but am unsure if I just would need to dissolve it in water, or rather to carefully neutralize it after dissolving
it.
Any suggestions are welcomed

Most of post deleted due to UTFSE was implemented by myself.

Googling suggests that anti-perspirants use aluminium chlorohydrate- Al2(OH)5Cl.2H2O
EDIT: thanks to spammers this relevant thread emerged

When I first used antiperspirants they left white stains on my shirts which did not wash out or only slowly. I traced the problem to the Aluminium in
the antiperspirant. When I switched to a none Aluminium containing antiperspirant no more white stains.
I would tell other guys with white stains on their shirts what probably caused them and some switched to antiperspirant not containing aluminium and
many concluded the white stains stopped.
I assumed the stains were aluminium oxide.

Yeah I don't know why you'd intentionally put aluminium in your deodorant. Smelling is bad, sweating is just mildly uncomfortable.
Basically the solution to the stain problem is to wear an extra shirt, but now your body is more insulated and you'll sweat even more! Sweating is
supposed to happen, it's how the body regulates its temperature. You will sweat less if you drink cold water.
