Over here in Borneo, I buy alcohol in 1 liter plastic cans or recycled beer bottles. The lables will generally say Spirit or something along those lines. Don't really know what's in them but they seem to burn fine in my Trangia so far.
It is likely an denatured ethanol (ethanol/methanol blend) based on the following chart. Does the lable say "spiritos"?
