First, let me give credit for the inspiration to the latest tutorial on M&P soap using only glycerin as a solvent and to the thread concerning pine rosin. I probably wouldn't have thought to try this recipe otherwise. When looking up the old ingredients for Pear's soap I found listed only 8 ingredients, water, saponified palm and coconut oils, glycerin, pine rosin, rosemary and thyme oils and pear essence fragrance. I didn't have thyme EO so I used cedarwood and lemon along with the rosemary EO. I also used Fresh Pear FO from Candlepro.com. This is a hot process recipe. The pine rosin is a bear to melt as it is gummy and sticky when heated. I suggest you melt it and the stearic acid along with Castor oil in the microwave. Add these melted ingredients at thin trace and stick blend. The mixture will seize, but don't worry, I just put the lid on my little crockpot and continued heating until the mixture loosened up and used the stick blender again to fully emulsify all of the ingredients. Here is the ingredient list: 144 grams Castor Oil 144 grams coconut Oil 144 grams palm Oil Few drops Vit. E. 18 grams stearic Acid 49 grams powdered pine rosin 72 grams sodium hydroxide 190 grams distilled water Melt the solid oils, (I used a small crockpot insert and melted the solid oils in the microwave.) Melt stearic acid and pine rosin together with Castor oil in a microwave safe container. Add lye water to palm and coconut oils and blend to thin trace. Add stearic acid, pine rosin and Castor oil mixture and blend. As I said, the mixture will get very thick quickly. Put the lid on the crockpot and heat until mixture loosens up and looks like it is separating. Hit it again with the stick blender until it looks like a thick trace. Cook, stirring every now and then, until mixture reaches Vaseline stage. Do a zap test. If there is no zap, add glycerin to the mixture and stir. Heat until all the paste is melted into the glycerin. Take off heat and add the FO and EO blend. Stir well and pour into mold. I used Bramble Berry's 12 bar mold. After the cook add: 499 grams glycerin 3.4 grams cedarwood EO 3.4 grams lemon EO 3.4 grams rosemary EO 4 grams Fresh Pear FO Hope this makes sense. If you have any questions just ask and I will try to help.
