I have been wanting to make my own soaps for at least a decade, but was terrified of using lye. So I moved onto other things, like lip balm and hand bound books, and placed my dreams of soap making on the back burner. That is, until this past summer when I began looking for things to do during #the100dayproject and came across a few hot process soap recipes. They looked easy enough and even had VIDEOS showing what it looked like when adding lye to water.
So I invited a friend over while Anna was at school to make a batch, We ended up making coconut oil shampoo bars (which I absolutely LOVE and still use). My friend and I both found the process to be easy and enjoyable and were thrilled to be using a product we had made ourselves.
With that first attempt being such a success, I decided to give it another go. This time opting for a bar that I could use in place of our body wash. I settled on a very basic bar using a mix of olive and coconut oils to get a baseline for what made my skin the happiest. I also wanted to play around with scents since we opted to keep our shampoo bars unscented.
I am fairly happy with how this batch turned out. It leaves my skin feeling soft and moisturized while also smelling lovely in the shower. The only thing that I would change is the amount of lather it creates. Perhaps I’m just used to the shampoo bars which have the most luxurious lather around, but these take a bit more work to get the bubbles out.
Are you a fan of hot process soaps? What’s your go-to soap recipe?

Coconut + Olive Oil Hot Process Soap
Course: Crafting4
servings30

minutes1
hour10
minutesIngredients
125 grams Coconut Oil, 76 degree
325gramsOlive Oil
165.78gramsDistilled Water
66.31gramsSodium Hydroxide (Lye)
Directions
- Weigh all of your ingredients.
- Turn crockpot onto low and add coconut and olive oils.
- While the oil is warming up, add water to a lye-safe container (#5 plastic is the only thing recommended). In a well-ventilated area (or outside) and while wearing your mask, gloves, and long sleeved shirt, slowly add the lye to the water while stirring. Once the lye mixture transitions from cloudy to clear, bring it inside and let cool for 5-10 minutes.
- Once cool, add lye mixture to your crockpot and stir.
- Grab your immersion blender and work it around your crockpot in a figure eight motion. Continue doing this in 20 second intervals of blending and stirring with the immersion blender off until you achieve trace (when the mixture has the consistency of pudding).
- Cover and cook on low for 30-45 minutes. Keep an eye on your crockpot, as the mixture will rise and fall. If your crockpot isn’t big enough, it could leak out the sides.
- To test if your soap is done, either use a pH strip or do the “zap test” (put a little of the cooled soap on your tongue and if it zaps you, it needs a bit more time).
- Once soap is done, pour it into your molds and let set. Soap will be ready to unmold when it comes off of the mold easily or has hardened enough that your finger doesn’t leave an indentation when you press on it. This could take anywhere from several hours to 3-4 days depending on your environment.
- Remove soap from mold and cut into bars.
- Store in a cool, dry spot (basements are good for this) and allow to cure for 4-6 weeks.
Notes
- Because of the high olive oil content of the soap, longer cure times are recommended.
- For those that want percentages to make it easier to run through a soap calculator (which is always recommended), they are as follows:
Coconut oil = 25%
Olive oil = 75%
Superfat = 10%
Lye to water ration = 2.5:1

October 4, 2020 at 10:53 pmHi! It’s always a good idea to run any soaping recipe through a soap calculator. That way you can learn about the qualities of the soap and also make sure your lye amount is within a safe range.

October 5, 2020 at 7:30 amWhere do you seem to be struggling with your soap making? What do you mean when you say making a mess?
As for soap calculators, my favorite is SoapMakingFriend. I find it really easy to use.
There are also several great beginner soap making groups on Facebook that have a ton of resources.

October 5, 2020 at 2:18 pmWhen I made my first batch the soap didn`t harden it stood liquid. The second batch of soap it stated to crumble like granola the third batch the bar when I used it it started melting in the bathroom when I wet it with water it was very soft. I just checked the soap making friend and this what is says. https://www.soapmakingfriend.com/soap-making-recipe-builder-lye-calculator/“

October 5, 2020 at 9:02 pmHow are you making the soap? Are you doing hot process soap or cold process soap? How are you bringing it to trace? And what is your cure time? All soap needs to cure for best results. I know that I said you *could* use the soap right away, but you’ll get the best results after a 4 week cure time. (I’m going to update the post to reflect that.)
Whatever you sent me through SoapMakingFriend didn’t come through. Sorry I can’t help you there. I did plug in the info into the calculator myself and it come up with different information. So I’m updating the post to reflect that and will be adding some photos to the post to clarify what properties the soap has and percentages to use (since that seems to be easier). Thanks for having me relook at this because it clearly needs to be updated. It’s one the very first soaps I made, so didn’t have much knowledge about soaps when I made it.
A few courses/groups I’d recommend looking into:

April 1, 2021 at 10:30 pmI would suggest using a soap calculator to verify you have the right amount of oils and lye.
