Homemade Pumpkin Soap Recipe

© Rebecca’s Soap Delicatessen


10.5 oz. pomace olive oil
6.6 oz. sustainable palm oil
13 oz. 76° melt point (refined) coconut oil
5 oz. rice bran oil
1.5 oz. shea butter
1.3 oz. cocoa butter

5.1 oz. lye/sodium hydroxide
8.8 oz. distilled water

2.5 oz. organic canned pumpkin
2 oz. fragrance oil of choice, optional
pinch each of yellow oxide and red iron oxide pigment powders, optional


To create this homemade pumpkin soap recipe you’ll need to follow my basic cold process soapmaking instructions. This recipe will fit inside one of my DIY wooden loaf soap molds and will yield approximately 10-12 bars of homemade pumpkin soap depending on how they are cut.

Begin by mixing your lye water. Weigh out the water and lye using a digital scale then slowly pour the lye into the water. Mix well until all the lye has dissolved then set aside to cool.

Now weigh out the soapmaking oils and butters and combine in a large stainless steel pot on the stove. Heat over medium heat until all oils are melted, then remove from heat and set aside to cool.

Once your lye-water and soapmaking oils reach around 95°F-100°F you’re ready to make soap.

If you are planning to add a colorant to your soap, start by adding a pinch each of yellow and iron oxide pigment powders to your soapmaking oils and then mix well with a stick blender.

Next slowly pour the lye-water into the soapmaking oils and mix until you reach a light trace. Add the pumpkin and mix again until it is fully incorporated then add the fragrance oil if desired and continue mixing until your soap has reached a full trace.

Pour the soap into your prepared mold, cover and insulate. After twenty-four hours have passed you can unmold your soap and cut it into bars. Allow soap to cure 3-6 weeks before using then wrap and label as desired.

  1. Hi! Just wondering if you’re from Northeast Pennsylvania? Thanks

  2. Hi Rebecca,
    Do you mash the pumpkin before adding? Can you share on how the pumpkin is prepared? I am thinking of using pumpkin bought from the market. Thanks.

  3. Gorgeous soap! Have you tried it with fresh pureed pumpkin instead of canned? You gave tips to another commenter on how to puree the fresh pumpkin, but I was curious if you had tried it in your soaps? I usually like to roast pumpkin in my oven myself instead of using canned for homemade pumpkin pis, but I wasn’t sure how it would fare as a soap ingredient (maybe due to more or less processing, liquid content, etc.). I’d be curious to hear your thoughts! 🙂

  4. This looks WONDERFUL, but I have a question… How do you think it would work using vegetable glycerin rather than lye? My daughter and I are both allergic to lye, so we’ve been using liquid soaps. I did find a local soap maker who uses vegetable glycerin. I tried it and no rash! YEA! I’d love your ideas on converting this to a glycerin-based recipe. Thanks!

    • You can use glycerin to make soap. All soap is made with fats (oils) and an alkali (lye). There is no lye left in the final soap as it’s used up in the saponification process. You can’t use fresh pumpkin in any melt and pour glycerin soap as it’ll go bad. Everyone is “allergic” to lye as it causes chemical burns when in pellet, liquid or flake form. It shouldn’t make any difference to skin in the resulting product.

  5. Just tried making it, the moment I added the pumpkin to the recipe, the oil separated. It’s in the molds but dosent look like it will come out good at all, any suggestions?

    • Once you added the pumpkin did you mix it again until full trace? You can try rebatching it. Or if you try it again, try mixing the pumpkin into the oils prior to adding the lye-water.

  6. Could you make this pumpkin soap using the crock pot hot process method?

  7. I’m sorry, I read through the comments here and am just a tad confused. Is it possible to use glycerin, melt and pour, with the *canned pureed pumpkin* or is the canned (store bought) still considered “fresh”?

  8. Can I replace the other oils with coconut and olive oil and it still come out okay?

    • You’d essentially be creating a new recipe. You’d have to run it back through a lye calc for the new lye amounts and depending on the oils used it could completely change the outcome of the final bar based on the properties of those oils in soapmaking.

  9. very beautiful soaps …
    could u attach the website of the lye calculator that u use???
    i would love to try the pumpk
    in soap but not use all the oils

  10. If I use my simple recipe of Olive oil, Coconut oil. Castor oil.
    Do I have to discount the distilled water for the pumpkin ?

  11. Hi! How much Pumpkin Puree shour I use ppo?


  12. hi I’m just wondering what would be the ideal fragrance combinations for this soap?

  13. I was curious as to what the best oil to use in place of rice bran oil. I have sunflower, safflower, and olive oil

  14. How many pounds of soap is this recipe for? I have a 4lb. mold and I’m wondering if it will fill the mold? Thank You

  15. i substituted olive oil for the pomace. I don’t know how to recalculate the lye water ratio with the pumpkin purée. Lye calf does not offer the option of adding pumpkin.
