- FIRST PART OF RECIPE - Making CP Bars. If you already have (4) approximately 4-5 oz. bars of cold process soap, skip to Step 12.
- NOTE: This project and these instructions have been written for someone who has experience making soap and knows the potential dangers due to working with sodium hydroxide. It will not outline all safety methods of working with dangerous chemicals, it is simply a soap recipe for advanced soapmakers.
- Put on your protective gear. This is very important since you will be working with an extremely caustic base that can and will burn you if you touch it. Noxious fumes are also released from the exothermic reaction that occurs when you mix the sodium hydroxide with water.
- Wear a face mask or leave the vicinity quickly after stirring the sodium hydroxide into the water. If you get any lye on your skin just wash it off quickly with copious amounts of cool water.
- Prepare the lye solution by weighing the water and lye in two separate containers. Pour the lye into the water, carefully mix in a well-ventilated area and set aside to cool while you prepare your oils.
- Weigh the Coconut 76° Oil and heat on low until it has melted.
- When the oil and lye/water are both approximately 110°F, pour lye/water mixture slowly into the melted oils/butters. Start mixing with stick blender.
- At light trace, add 0.875 oz. of Coastal Cottage Fragrance Oil and blend lightly.
- Pour soap into Short Loaf Silicone Mold. (When we tested, this soap heated up very quickly. We would recommend placing mold in the refrigerator.)
- Let soap set in mold overnight. If it sticks to the sides of the silicone mold, let set for an additional 24 hours before unmolding.
- Unmold soap and slice. Let cure for 4-6 weeks.
- SECOND PART OF RECIPE:
- Finely grate (4) 4-5 oz. bars of CP soap and set aside.
- Measure 27 oz. of Sodium Borate and 28.6 oz. of Sodium Carbonate and mix into the grated soap.
- Working in small portions (about 2-3 cups at a time), put mixture through a food processor. This helps to get the soap into smaller pieces that will dissolve more easily.
- When the entire mixture has been processed, fill each bag to approximately 8.75 oz. Depending on the size of your CP bars before grating, you may have extra product after filling the 9 bags. This can either be divided up between the bags or used for samples.
- Insert a scoop and seal and label the bag.
- DIRECTIONS FOR USE: Use 1 Tbsp. per load. If extra large or soiled load, use 2-3 Tbsp. If using cold water, try to dissolve the soap in water before adding clothes.
- NOTE: This recipe is a low-suds detergent and should be safe for HE (High Efficiency) machines, but check with the instructions that came with your machine to make sure before using.
