What is HP Soap?
HP is “hot process” soap. It is called hot process because the saponification process is acellerated with heat. The is soap made similar to cold process soap ~ using oil/fat/nut butters, lye and water. The ingredients are brought to trace. The soap is then exposed to heat and “cooked” through the saponification process, usually in a crock pot or double boiler. At this point fragrance and color added and the soap is place into a mold. The hot process somewhat changes the appearance of the finished soap, but allows the soap to be fully saponified and immediately ready for use within a few days.
