Soap Curing - why soap needs to cure

Are you wondering why cold and hot process soaps have to cure for so long? According to MakeBathProducts.com there are several reasons why soap has to cure. First of all, it depends on the process but a batch of soap can cook during the process. Hot process will cook each batch of soap over a heat source, speeding up the process of the saponification process (the lye) and continues to evaporate the wax. With cold process soaps nature takes care of the curing process by allowing the soaps sit out in the open. Another reason why some soaps need a longer cure time has to do with their ingredients.
