a) Addition of Pure Alcohol will speed up the Saponification process. As Pure Alcohol exists in all Artificial Scents, hence by using one with high concentration of Pure Alcohol (e.g. any Rose essence), will introduce “spontaneous” Saponification. This, however, also means that, if any Artificial Scent with a high concentration of Pure Alcohol is used in the recipe, moulding needs to be worked quickly as soon as it is added.
b) On the other hand, if the soap mixture is not thickening as expected during the whisking step, adding a few CC of Artificial Scent containing high concentration of Pure Alcohol will solve the problem.
c) Adding Powder[1] of any sort to the Soap Mixture also helps to harden the end product. This is another way (other than adding Artificial Scent) to expedite Saponification.
9.SuperFatting
SuperFatting is when the amount of Oil exceeds the amount of Lye added. Theoretically, the higher the amount of oil in the soap the better it is for the skin (and vice versa for the Lye), however, the more “Oil over Lye” the faster the deterioration, hence SuperFatted Soaps are not made commercially.
