Lemon Soap




Introduction: Lemon Soap

These instructions will teach basic techniques of how to make your own homemade lemon soap assuming you have never created soap before. Whether you are a crafty person looking for a project or you are looking for a more natural alternative to commercial soap, making soap is fun, and addictive. There are several different methods to making soap, and once you understand the basics you will soon be adding your favorite fragrance essential oils that commercial manufactured soap can’t even begin to compete with.

Warning and Caution:

Creating soap is a chemical reaction. In the steps ahead you will be creating mixtures using lye. It is important to wear gloves and protective eyewear as mixtures will get really hot and dangerous. It is also important to make sure all the lye is converted or the finished soap can burn. The instructions will provide you additional detail and information on how to make sure all is converted and well.

Material and Equipment

35 oz lemon oil

6 oz lye

10 oz water

1 oz additional essential oils ( optional and of your choice) * only if you want to mix and add different smells


Stick blender

Crock pot


Plastic spoon

Glass measuring cups Scale

Soap mold Glass bowls

Step 1: Set Crockpot to Low and Weigh Ingredients.

Step 2: Add Water to the Glass Bowl and Slowly Add the Lye to Water While Mixing.


Do this while wearing your protective gear and do not breathe the vapors. Order is important so make sure you are pouring the lye into the water. The mixture will get very hot so place to the side for 10 minutes while you work on step 3.

Step 3: Place Lemon Oil in a Saucepan and Heat to 130F

Step 4: Place Lemon Oil Into the Crockpot.

Step 5: Add Lye to Crockpot and Stir

Step 6: Using the Stick Blender Mix Until the Mixture Has the Texture of a Light Pudding

Step 7: Cover Mixture and Let Cook on Low.

Note: It is important to make sure all the lye is converted. You will notice the oils rising up to the sides and folding back into the mixture. Allow it to cook for 45 minutes- 1 hour. When ready the soap will look like Vaseline with no oil puddles in the middle. To double check, take a little of the soap and rub it between your fingers. It should feel waxy.

Step 8: (Optional) If You Are Adding Essential Oil, Wait Until the Mixture Cools and Now Add Them.

Step 9: Spoon Mixture Into Your Mold and Allow for It to Cool.

Step 10: Cut Bar As Soon As It’s Cool and Firm.

Most bars need 24 hours to harden

Step 11: Place Bars on a Rack and Allow Them to Dry Out and Harden for an Additional Few Days

Step 12: Try Out Your New Lemon Soap Bar!

    Is the "lemon oil" a blend of lemon essential oil and another oil? Like coconut or palm oil? The amount tells me it's more than just essential oil but I don't know what it is...

    Where do you get lemon oil and lye?


    7 years ago

    You cannot call soap organic because all soap requires lye in order for it so become soap, and lye is a man made product.

    Mmm... I love citrus soaps. I'm addicted to Lush's sexypeel soap! I'll have to try making some of these. There are dozens of lemon trees in my neighborhood. Do you think I could press their peels to get the lemon oil?

    Yess! you can use lemon peels to get the oil but you would have to heat the peels with a double boiler and a cup of oil. http://blahblahmagazine.com.au/lemon-oil/

    I have also just used the peels before in dried form for exfoliation and decoration. the peels are rather hard so grind them up before adding it to your batch. You'll love it!
