For a half gallon, this is an AMAZING price. What do you use vegetable glycerin for, you ask? Lots of things :) This stuff is a godsend to people with really dry, chapped skin (especially in the winter time). It feels sticky at first, but sinks into the skin giving the essential moisture you're missing. I like to put on just a little (less than dime size) and to skin that is slightly damp, I feel it absorbs better that way.
You can also use this in recipes. A lot of people add a little of this to their ice cream when making because it keeps it less "icy" when frozen. I have also made low carb, sugar free "marshmallows" with this as well! Such a hit, tastes amazingly sweet for no calories. And the half gallon jug will last you FOREVER!
