Indeed.
The LD50 of isopropyl alcohol is 5000 mg/kg (oral, rat). Just as a comparison point, the corresponding one for a common fingernail polish remover–acetone–is 5800 mg/kg. Extrapolating to humans is always tricky, but this does mean that for rats, at least, isopropyl alcohol is more poisonous than fingernail polish remover.
But please, tell me more about mixing a food product with a poison and spraying it around the kitchen to avoid “harsh chemicals”.
