Making your own homemade liquid coconut oil soap is simple, thrifty, and very rewarding. Coconut oil soap provides lots of lather and cleaning power for all purpose cleaning. Makes 1-2 Gallons of soap (See notes below.)

Prep Time 30minutes
Cook Time 4hours
Total Time 4hours30minutes
Servings 5lbs. soap paste
32oz. coconut oil
8.59oz. KOHThis is not lye (NaOH) that is used in bar soap.
Melt the coconut oil in a slow cooker pot over low heat.
Meanwhile, mix together the water and glycerine, and measure out the potassium hydroxide (KOH).
Pour the KOH into the water and glycerine mixture. (& not the other way around!!) Mix well until the KOH is fully dissolved into the water/glycerine. It will be cloudy at first, but will clear up.
Carefully pour the KOH mixture into the warm coconut oil, and slowly mix them together.
Using a hand blender, blend the ingredients together in the slow cooker. The mixture will begin to thicken after a few minutes.
A couple of minutes later, the mixture will begin to look grainy. Continue to blend.
If the mixture becomes too thick to blend with the hand held blender, switch to mixing with a wooden spoon, or even a stainless steel fork, if need be. Unlike the olive oil soap, which I was able to blend with the blender throughout the entire process, with the coconut oil soap I did have to stop blending with the blender and switch to a wooden spatula and stainless steel fork. (You can read more about that above.)
The mixture will continue to thicken and will become more translucent. We are working on making a soap base paste to dissolve into a clear liquid soap. The process will take 3-4 hours, and you should check it and stir it up every half an hour or so.
To check for "doneness," we will look to see if our paste is dissolving into a completely clear liquid soap. To do this, take a small amount of the soap paste and dissolve it in water, checking to see if the water is clear once the soap paste is dissolved. If the liquid is cloudy, you will want to continue to cook the soap in the slow cooker. Stir it up and let it cook for another half an hour before checking on it again. If it dissolves clear, you are finished making the soap paste.
Your liquid coconut oil soap paste is now ready to be stored or dissolved into liquid soap as needed.
This recipe makes 4.5-5 lbs. soap paste which can be diluted to 10-20lbs. soap or more. That ends up being 1-2 gallons, or more, depending upon desired concentration.
Keep in mind that liquid soap is not as thick as commercial gels and surfactants. Liquid soap is of a thinner consistency. You don't need to keep it thick for it to be concentrated and work well.
