I think you'd probably want to ask a vet that. Maybe birdvet can chime in here! If you can get the MSDS safety sheet for the product, that might give you a clue.
Here's the kicker -- what, exactly, does non-toxic mean? I don't think the use of the label "non-toxic" is generally regulated and it would in any case typically refer to "in normal use". Since most things are toxic in sufficient quantity, dosage is IMO a critical concern, and dosages for parrots seem to be tiny, tiny, tiny compared to even very young children. It's like a product being labeled "natural" -- it means nothing in the way of a guarantee. Organic, now, is a label that has a meaning. I did a brief online search, and while I think there are some organizations that grant seals, I can't find evidence that the label "non-toxic" is regulated or policed. Maybe someone else knows more about it?
Here is an example -- I use polymer clay in my jewelry work. It is considered nontoxic (think Sculpey). But it is not healthy to eat it, and the fumes created by burning it are quite nasty. I'm very careful with ventilation even when curing it normally. And while it is nontoxic and some brands are designed specifically for children to use, the manufacturers caution you never to make drinking or serving vessels where the food or beverage would directly contact the clay with it. Hence I avoid any contact between it an my birds, wash hands carefully after handling it, etc.
