Thread: alum?

Am i wrong to think that i could use this instead of an alum block? i already use it as a deodorant and i think (or hope) that it works fine. I think its the same material/crystal and for some reason i feel as the form factor is suitable for travel. Also, the spray seems like something that might have some practical applications in the shaving world if it is the same as the material used to make alum blocks.

Crystal Body Deodorant

I use it all the time and it works great!!!!!!

the spray or the actual crystal?

the actual crystal

It doesn't actually say what its made of. Many of the xtls made for under arm use contain ammonium alum as opposed to potassium alum. If its the ammonium variant I wouldn't use it.

it's potassium alum
