Is glycerin that's used for a skin protectant the same thing as the glycerin that's used for making fondant?

Answer 1

Yes it is sometimes used as a non fermenting sweetener in cheap dry wine.

There are both food-grade and NON-food-grade glycerin, so be careful when you buy it; non-food-grade glycerin is usually sold in drug stores, and is intended for external use only. Read the label to make sure it's what you're looking for.

you can find food-grade glycerin in some largeer grocert stores, cake supply and craft stores (such as Michael's). There are also numerous sources on-line.

Answer 2

Sort of. There is "food grade" and "non food grade" glycerin; it's like having meat that's fit for human consumption, and meat that's not fit for human consumption - both are meat, but manufactured to different quality standards. It's a similar case for glycerin.
