not really. Glycerine can be purchased very cheaply and is much cheaper and easier to just buy instead of make yourself from salting the soap. It also affects how the soap feels. Because of commercial facilities only making components, a large soap manufacture might buy those components and add back some glycerine that was removed. It's why you sometimes see glycerine as an ingredient.
Also anything is an explosive when you nitrate it (normally with nitric acid)
