https://www.amazon.com/Gorilla-Super-Glue-gram-Clear/dp/B082...
First two photos are the front and back of the package. Care to point out where it says what the ingredients are? Because I sure can't find it.
I could trivially find a hundred other examples. So I don't know where you get the idea that hardware ingredients must be listed on packaging.
