This coconut oil facial soap recipe is palm free and will yield 10 bars of soap approximately 5 oz. each depending on how they are cut. This palm free cold process soap recipe will fit inside my DIY wooden loaf soap mold.
As this lemongrass and neem oil soap recipe has a high amount of olive oil and doesn’t make a super hard bar – it rates a 39 for hardness out of the recommended 29-54 range at SoapCalc (learn more about using lye calcs here) – I added a small amount of sodium lactate to the recipe. This is optional. If you don’t have palm kernel flakes on hand – which are included for both lather and hardness – you can substitute with palm kernel oil. Alternately, you can also make this homemade soap recipe palm free by substituting the palm kernel flakes with lard. If you make substitutions, however, you MUST run this lemongrass and neem oil soap recipe back through a lye calculator.
For visual interest I added two bars of soap to this recipe. I simply cut them into cubes and placed the soap cubes inside my prepared soap mold before pouring the soap. The two bars of soap I used are my Lemon & Poppyseed Soap (recipe here) and my Natural Black Clay & Sea Salt Soap (recipe here.) Adding the soap will increase the final weight of the soap bars to around 6 oz. each.
I did use a fragrance oil for this soap recipe. However the sage side of the lemongrass sage fragrance oil I used was a bit too potent for me, so I made it a little more lemon-y by adding the lemongrass essential oil and the tea tree oil which rounded it out quite nicely. You can always omit the fragrance oil from this homemade soap recipe if you’d like a completely natural soap bar and simply increase the amount of the essential oils used.
You’ll need to follow my basic cold process soapmaking instructions for this natural lemongrass and neem oil soap recipe.
(If you’ve never made cold process soap before here’s another good, inexpensive beginner’s cold process soap recipe. Or download my free beginner soapmaking ebook.) Be sure to take all proper safety precautions when working with lye including goggles and gloves.
Begin by measuring out the distilled water in fluid ounces. Pour into a heat safe pitcher. Next, using a digital scale weigh out the lye. Slowly pour the lye into the water in a well ventilated area and stir until all the lye has dissolved. Set aside to cool.
Now weigh out the eight soapmaking oils and butter using a digital scale and combine in a stainless steel pot. Heat until the oils and cocoa butter have melted completely, then remove from heat.
Now prepare your fragrance oil and essential oils by weighing them out into a glass Pyrex measuring cup. Set aside.
Measure out the kaolin clay into a small container and also set aside.
When the lye-water has cooled to around 90°-95°F – you want the soapmaking oils and lye-water to be about the same temperature – you’re ready to make soap.
Measure out the sodium lactate and stir into the cooled lye-water.
Add the clay to melted and cooled soapmaking oils. Mix with a stick blender until thoroughly combined.
Now slowly pour the lye-water into the soapmaking oils. Mix with a stick blender until you reach a light trace, then add the fragrance and essential oils. Mix with the stick blender until you reach a medium trace.
Now pour the soap into your prepared mold. (If you are using a wooden soap mold you will need to line it first.)
Level the top of the poured soap with needed. Then lightly cover the top of the mold with a section of cardboard and set aside in a safe location where it won’t be disturbed.
After 24 hours your can unmold your lemongrass and neem oil soap. (If you omitted the sodium lactate and your homemade soap is still soft, simply wait an extra day before unmolding.) Once you’ve unmolded your soap, cut it into bars and set them aside to cure for approximately 4 weeks before use.
Once your natural lemongrass and neem oil soaps have cured, simply wrap your soap bars and label as desired. (Go here to learn how to make your own custom soap labels.)
