L.S., some time ago there was a discussion about the possible toxicity
of Al compounds. I remember e.g. uncle Al saying that Al-citrate is
hazardous because it is uncharged and by virtue of its neutrality it
can be absorbed in the GI tract. Charged species would not be able to
pass the cell membrane, but uncharged ones would. I thought what about
Al-stearate then? This is almost insoluble in water but soluble in many
oils and solvents -a lyophilic species. Al-stearate as far as I know is
much used in foods and in plastics as an antilumping
agent/lubricant/plasticizer. Since it dissociates into ions with some
difficulty and it is fat-loving I can imagine it could be hazardous
too. Any comment? Thank you. Regards, Folkert Dekens.

Certainly hazardous when dropped as part of an old fashioned napalm recipe.
