Liquid And Solid Glycerin Vegetable Glycerin And Glycerin?

Vegetable glycerin and Glycerin? - liquid and solid glycerin

I had to use this recipe for my lips

http://www.ehow.com/how_2222982_beautufu ...

but I went out and put a laxative, the use of glycerine for medical purposes in the pharmacy. was in solid form.

I think I'll buy vegetable glycerine, which in liquid form.

How do they work the same?
But, as the recipe calls for liquid, but I made strong, how to make money?

I do not want to take a loss of $ 4, what can I use?
