Production

Glycerin soap are made through melting and continuously heating soap until the mixture has reached a clear jelly-like consistencyCitation | first = Kathy | last = Miller | title = Tips on Making Clear Glycerin Soap| year = 1997 | publisher=Miller's Homemade Soap Pages| url = http://www.millersoap.com/glycerinsoap.html | accessdate=2008-09-02] . The cooking process requires that the soap be partially dissolved with high proof alcohol. With home and hand-made soaps that still contains glycerin left over from saponification, the grating, melting and cooking of the soap can proceed without the addition of anything into the mixture, however sugar or additional glycerin is sometimes added. Glycerin soap can also be produced without remelting soap through directly cooking raw home-made soap.

In industrial soap-making, the glycerin is then usually removed. As such, to produce glycerin soap a good quantity of glycerin must be added back into the mixture prior to melting.
