Toy safe usually is usually the same standard as being food safe as it means it can be sucked and chewed by kids. My main concern is if it comes of in the liquids I would be putting it in. We'll see. As i said I have ordered some and I have some old goblets I can use it on to experiment. see what it's like. I'll post the results. At the cost per litre, which is anything up to 1/4 the price of other hard wax oils, it is worth 'avin' a go.
