No,it wouldn't be worth risking.Plus,you can get soy paint cheaper and it doesn't come in white but it does have a decent range of nice colors!

Or for the full range of colors the actual manufacturer's website is better

For white paint,it isn't really possible to find a reasonably priced natural and nontoxic paint so something like an off white or cream is the closest you'll get.For other colors you can sometimes do berry based dye or other fruit dyes,but these have to be nontoxic fruits to be safe.
