Cold Process Neem Oil Soap

I’ve been using a neem oil in a lot of my different diy skin care recipes lately and have loved the results. So I finally created a natural homemade neem oil soap recipe with neem oil as one of the key ingredients. This homemade neem oil soap recipe is formulated specifically for those with eczema and psoriasis as well as scalp conditions like dandruff and seborrhoeic dermatitis.

My neem oil soap makes a great body bar for natural skin care. The carrier oils I chose for this cold press soap — specifically argan oil, apricot kernel oil and wheat germ oil — make it suitable for use as a no poo shampoo bar as well. The lemongrass essential oil in this cold process recipe help to mask the natural odor of neem oil. However you can also substitute the lemongrass with lavender essential oil, if you prefer. Or explore other ways to cover up the smell of neem oil here.

To make this recipe for homemade neem oil soap, you will need the following ingredients:

How to Make Homemade Neem Oil Soap

To make this homemade neem oil soap recipe, you will need a suitable soap mold. This recipe fits inside one my DIY wood loaf soap molds.

I order to recreate this homemade soap recipe with neem oil,  you will need to follow my basic instructions on how to make cold process soap. If you’ve never made cold press soap, then I recommend starting with a more basic recipe as found within my soap making tutorial. You can also start with some of the homemade soap recipes found in the books, Soap Crafting by Anne-Marie Faiola and The Soapmaker’s Companion by Susan Miller Cavitch.

Here is how to make neem oil soap from scratch using lye:

  1. Begin by lining your mold and taking all necessary safety precautions. Then measure out the distilled water into a large glass pyrex measuring cup or pitcher. Now, using a digital kitchen scale, weigh out the lye then slowly pour into the distilled water in a well ventilated area. Stir until all the lye has dissolved then set aside to cool. Weigh out the essential oils separately and set those aside as well.
  2. Now weigh out the soapmaking oils and butters and combine in a large non-aluminum pot. Heat on the stove over medium heat until all ingredients have melted. Then remove from heat and allow to cool.
  3. Once your lye-water and soapmaking oils have cooled to between 100 and 115 degrees, you can start making soap. Begin by slowly pouring the lye-water into the soapmaking oils and then mixing with a stick blender until you reach a light trace. Add the neem oil and lemongrass essential oil and mix thoroughly, then pour your soap into the prepared mold.
  4. Cover and insulate for 24 hours. After this time you can unmold the soap and cut it into bars. {Learn how to make a soap cutting guide here.} Allow your homemade soaps to cure for 3-6 weeks, then wrap as desired with professional plastic food wrap film, Kraft paper, or even fabric prior to labeling your products.

If you’re making these homemade soaps to sell online or at farmers markets, you’ll need to include the weight of each bar of soap on your label as well as adhere to any other state and federal laws.

    Hi Rebecca!
    Love the sound of this recipe. Can these batches be cut in half and still turn out? I would like to make 5-6 bars of the various soaps, but do not want to compromise the quality or “botch” the batch.
    Thank You So Much For Sharing!

      You can re-size it. Be sure to run the new amounts back through the lye calc. Do not include the neem oil in the calculations for lye and water amounts and superfat at 6%.

    hello, i would like to know if anyone can help me with this recipe for dog soap. i plan to use a 1lb melt and pour base (dont want to seal with the lye) and add these essential oils to it: eucalyptus essential oil, tea tree essential oil, cedarwood essential oil. but im not sure how much of each essential oil i should use. i would appreciate the help. thanks

      Essential oils are generally added to cold process soap at 1-3% and half that for melt and pour. Hope this helps.

    Hi,neem oil is awesome, i have neurodermitis and it helps, im making soap bar/shampoo for my father, who has psoriasis on his scalp, and im wondering if it is possible to substitute argan oil and wheat germ oil with some other oils, (for example castor, hazelnut…) and still use it as a shampoo bar?

    Thank you 🙂

      Of course. Just be sure to run it back through a lye calc as the SAP values of the oils would be different. I superfatted this one at 6%.

    Hi Rebecca, can you please tell me what other oil I could use to replace the palm oil!
    I’m looking forward to try this soap.

      There’s not really a straight up replacement for palm oil. You can experiment with another oil that makes a hard bar as one of its soapmaking properties but it’s likely to change the resulting soap and you’d have to run it back through a lye calc as the sap values will change.

    Hi, I’m wondering about the palm kernel oil flakes in this recipe, can it be substituted with regular palm oil? When I put them in the lye calculator there is a big difference between the two. I’d really like to try this but I only have palm oil and I don’t want to throw it off. Thanks for the recipe 🙂
