Should bonded leather not be called bonded plastic instead? By law?

Bonded "leather" is a new covering for upholstery which is usually only 17% leather and the rest polystyrene or some such a plastic. They atomize the leather and mix it in with the plastic goo. I have sat on it and it feels so-so. Nothing great, nothing bad. But what bugs me is that they call it bonded-leather. Isnt this misleading advertising? I regularly buy cooking oil which is a third olive and and two thirds vegetable oil. They dont call it an olive oil mix. They call it mixed-oil. And that is regulated by law. Why not the same with bonded leather. It is closer to being bonded plastic.
