7/26/16 - More Slow Cooker Soap:
The recipe below is what I used for this soap. I was well pleased with how easy it was to make. I used my smaller 4 qt crock pot without any problems. I did let the lye misture cool down to around 130, and also the cooled the melted oils to about 130. When I added the lye solution it seemed like it immediately started to thicken and reached trace in around 5 minutes. this batch fit perfectly in the silicone loaf pan. I did end up with a round bar because when it set up (that was very quick, too) I sliced off the crumbly top layer, added a little water, reheated in a saucepan then added it to a small mold.
Homemade Hot Process Soap Recipe in a Crock Pot
Author: The Prairie Homestead
Recipe type: DIY - Soap
· 10 oz olive oil
· 20 oz coconut oil
· 9 oz distilled water
· 4.78 oz 100% pure lye (135 g)
· Essential oils for scent (optional)
· Other Equipment:
· Digital scale
· Safety gear (safety glasses, long sleeves, gloves)
· Stick blender
· Crock pot
· Non-metal dishes and utensils
1. Measure out the olive and coconut oil.
2. Place the coconut oil in the slow cooker, and turn it on so it begins to melt.
3. Measure out the other ingredients, weighing each and every one on the digital scale first.
4. Once the coconut oil has completely melted, add the olive oil to the crockpot and allow it to mingle and warm up.
5. Add the lye to the water, stirring slowly. Do this in a place with ample ventilation, while wearing your safety equipment.
6. Add the dissolved lye/water mixture to the melted oils in the crockpot. Stir gently.
7. With the stick blender, continue to mix/stir for several minutes until you reach "trace."
8. Place the lid on the crockpot, set the timer for 50 minutes, and allow the mixture to cook on LOW.
9. If the soap tries to bubble out of the crockpot, give it a stir.
10. Line the soap molds with parchment paper (if required)
11. Once the 50 minutes has elapsed, perform the "zap test": I like to do this by grabbing a small amount of the soap mixture, allowing to cool for a second, and then touching it to my tongue. If it "zaps" me, I know there is still lye remaining in the mixture and it needs to cook longer. If it just tastes like soap, we're ready for the next step.
12. Allow the mixture to cool slightly before adding any additives.
13. Press/pour the soap mixture into the mold, making sure to press it into all the corners and smooth out the top as much as possible.
14. Set it aside for 12-24 hours, or until it sets completely. (Usually, overnight is plenty of time).
15. Remove the soap from the mold, cut it into bars.
16. Allow it to dry for another day or so to allow it to harden up a bit.
