I question that.. There are some pretty powerful bitterants available for this sort of thing. You don't need much denatonium benzoate to make something unpleasant to taste, for example: "Dilutions of as little as 10 ppm are unbearably bitter to most humans." https://en.wikipedia.org/wiki/Denatonium https://en.wikipedia.org/wiki/Denatonium
- sandworm101 11y agoBut isn't denatonium benzoate water soluble? Using that as a coating on batteries would make for a rather unappealing product. You wouldn't enjoy opening the package or handling the things with bare hands. Children's toys would be ruined by the smell.
- Gracana 11y agoOh, yeah I guess you're right, it's water soluble. I was thinking more "hygroscopic" when you talked about it ruining electronics, but I guess you just meant that if it got wet it would cause the device to have bitterant all over it forever. I don't think it necessarily needs to be that messy. It has no smell, and you can buy nail polish that contains the stuff (used to deter nail biting and thumb sucking), so apparently it can be painted on in a fairly durable fashion. Just a dot on the battery case ought to do it.
