caustic soda

Your pharmacies don't have it?? That's weird!

Maybe you can check paint shops. It has a use in removing paint from wood, sometimes.

It's also used to bake some special kind of buns. So I guess bakeries use it too, but this is pretty far fetched. It's a common chemical, really. Should be easy to get.

You should get it, one way or the other. I hope a local can point you in the right direction.
