The thing about IPA is how it reaches purity over the azeotrope with water. In the USA about 80% do this via adding benzene which is toxic. Even if distilled will remain a small portion. IPA is also slightly toxic on its own if not evaporated well like in oils/goos your body makes it acetone but large amounts are toxic. There are different methods and some countries have 'safer' isopropanol than others.

For small amounts it honestly doesn't matter just make sure to evaporate your material as well as possible.
