Homemade Raw Goat's Milk Soap

I am a soapmaker. It is not a career for me, just a very satisfying hobby. I get special orders from friends once in a while, but usually just make soaps for my family to enjoy. I first started making soap about the time that Hurricane Katrina came through New Orleans... my hubby was working with the clean-up efforts, I was home with 4 small children and needed an activity to keep me sane. :) Soapmaking found me, and I've been enjoying it ever since!

Recently, I became aware of a local goat dairy from which I could get raw milk- was I excited! I have made soap with canned goat's milk, but it's just not the same; even the technique to making the soap with raw milk is different. If you have ever made soap before, here's a recipe that you will thoroughly relish:

20 oz coconut oil
20 oz olive oil

12 oz goat's milk, frozen and broken apart.

6.08oz sodium hydroxide (NaOH)

The reason you need to freeze the goat's milk is that the NaOH will burn it otherwise. If you have ever burned milk, you know that it isn't pleasant- and the soap will be ruined! What's great about this technique is that the lye solution doesn't even get above 100 degrees, so as soon as the oil is heated to the correct temp. it's time to mix! No waiting needed.

Step 1: Mix your NaOH into the frozen goat's milk. **Please use precautions when handling lye, as it is caustic and can cause serious burns. Use eye protection and long gloves to protect any exposed skin.** Once the milk is thawed, leave the lye solution in a protected area.

Step 2: Heat your oils to about 100 degrees. This will not take long at all :)

Step 3: Mix the lye solution into the heated fats in a stream no larger than a #2 pencil. Stir with a metal spoon until incorporated.

Step 4: Using an immersion blender, mix the soap until a light trace (thin pudding consistency). Add any additives at this point, then mix until incorporated. I used about 0.3 oz ground lavender buds and 0.7 oz lavender essential oil.

Step 5: Pour your soap into a prepared mold. I used a commercial-grade 9x13 baking pan, lined with plastic. Cover your soap with plastic and wrap your mold in a blanket.

Step 6: Remove your soap when it hardens. This can take anywhere from a couple hours to a day. Cut into bars (From my pan, I cut 10 2 1/2" x 4" bars and several "samples") and let them cure for 2-6 weeks. **Always test the pH before using soap!**

The finished product is a cleansing, hydrating bar that makes a gazoodle bubbles! I can't wait to try this out in the shower and breathe the calming lavender scent... I have tried a couple sample slivers, and it is definitely one of my favorite soaps thus far!

  1. Thanks for sharing your recipe. Can you tell me what pH your goat milk soap usually ends up at?

    1. Mine has been curing for about a week, and it has a pH of 9. I don't expect it to get any lower.

  2. This soap sounds great! I'd love to try some! I'd really like to try making it too.

    1. I have a sample soap with your name on it! :) Unfortunately, all the large bars have been purchased. I will have to whip up another batch asap!

  3. I was curious, if your ingredients are measured according to weight or liquid volume?

    1. I measure everything by weight. Thanks for asking :)

  4. Are your oils in liquid form? How long does it need to cure?

    1. Since I measure by weight, the coconut oil doesn't have to be liquid. It melts when I heat my oils to 100 degrees. I usually let me bars cure for at least 3 weeks, but 6 weeks is ideal! Thanks :)
