How To Make Crock Pot Hot Process Soap For Immediate Use

How To Make Crock Pot Soap


I have been experimenting with fresh herbs in my soap recently but that requires the cold process method which needs 6 to 8 weeks to cure before you can use it.


But with the hot process soap making method the soap is ready to use immediately. All you have to do is wait for it to harden up, remove it from the mold and cut it.


You can find my original cold process soap making recipe and instructions here: How To Make All Natural Soap At Home


Making crock pot soap is very fast and easy though.


Ingredients and supplies for crock pot soap


I made a double batch and used three different kinds of oil. I used vegetable oil, organic coconut oil and organic olive oil. The three give you a nice, solid bar with good lather. And the soap is good for your skin with natural moisturizers in it.

Materials needed to make crock pot soap




Here are the ingredients:


16 ounces vegetable oil

8 ounces organic coconut oil

8 ounces organic olive oil

14 ounces water

4 ounces lye


The oil I had on hand was organic so I used that. It goes not have to be organic oil unless that is what you want.


You can mix up the amount of oil as you like but just keep the total amount of oil at 32 ounces. You can use all of one kind of oil or use a variety like I did.


Again this is a double batch so it will make a 2 pound bar of soap when finished.


Tools and Equipment Needed


Pyrex measuring cup

Plastic or silicone stirring spoon

Kitchen scale

Mailing envelope for measuring lye onto kitchen scale

Candy thermometer (optional)

Crock pot

Soap molds

Stick blender (optional but makes the job faster)


Making Crock Pot Soap


First measure your oil into the pyrex measuring container. Pour this into your crock pot and turn it on medium or high setting. When the oil is heated up, reduce the heat to medium or low setting.

Measure 4 oz of lye into a mailing envelope on top of a kitchen scale. Use caution when working with lye. It is recommded to use safety goggles, gloves and an apron to protect yourself from accidents. Also have some paper towels on hand for quick wipe ups.

Measure out 14 ounces of water into the pyrex measuring cup. Then slowly pour the lye into the water, stirring as you pour. Make sure all the lye is mixed in well. I put the pyrex cup on a coffee coaster at this point to keep it off the table. The lye and water mixture will reach about 150 degrees F.



Use a candy thermometer to check when the lye and water mixture reaches about 100 degrees F. At this point you can slowly stir the mixture into the oil in the crock pot. You will see tiny particles of soap forming as you stir in the lye.

Now either stir and stir and stir..... until you reach trace. Or use a stick blender to rapidly mix in the oil and lye mixture until you hit trace. Generally with the blender the entire process can be done in about 15 minutes. The old fashioned method of stirring by hand takes many hours.

Once you hit trace (see article and video link above), put the lid on the crock pot and wait. The next stage can take one or two hours, depending on your crock pot. When you see the soap hits the gel stage, I give it a bit more stirring. The soap will take on a clear color.


At this point I stir a bit more and the soap turns into a thick oatmeal consistancy. Now the soap is ready for the ZAP test.


The ZAP test is often compared to putting a 9 volt battery on the tip of your tongue. You will get a little, harmless zap from it. Touch a bit of soap to the tip of your tongue. If you get a zap, leave it to cook a while longer.


When you no longer get a zap, the soap has been thoroughly cooked and is ready to pour into molds.

Now the next process I prefer to do quickly because the soap can set up sort of fast sometimes.


I pour the soap into the mold. Then scrape out the crock pot well. Next smooth out the surface of the soap as well as you can. It is often lumpy and thick so you will not get a perfectly smooth surface.

Leave the soap to harden up overnight or for a couple days.


Now you can remove the soap from the mold and cut it into one inch thick soap bars.


Your soap is ready for use immediately. Or you can leave it out to cure and harden up for a week or so. This gives you a nice firm bar of soap which lasts longer.

The soap recipe I used here gives you a firm bar of soap with nice lather. It smells sweet due to the natural moisturizing glycerin content in the oils. This soap cleans well and is good for your skin.


I use this soap for washing hands, hair and body in the shower, washing dishes and laundry. Basically you can use this soap for anything where soap or detergent is needed.


To wash laundry I simply scrape off a little bit of soap into the washing machine. This soap gets your clothes very clean.
