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.
