More toxic than what? I assumed you meant than methanol (which is added to ethanol-based cleaning products in the Netherlands), but then I read this on the Wikipedia page for isopropyl alcohol:
>Isopropyl alcohol, via its metabolites, is somewhat more toxic than ethanol, but considerably less toxic than ethylene glycol or methanol.

"Even more toxic" is not usually the preferred phrasing for comparing with ethanol; it implies you're comparing with something that's already quite toxic, and ethanol, while indeed toxic, is not normally considered quite toxic enough that we don't need to go out of our way to stop people from drinking it.
