Coconut + Olive Oil Hot Process Soap

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.

By Emily Levenson – Serves: 8-10 bars

Prep Time: 30 minutes – Cooking Time: 1 hour

Try your hand at soap making with this beginner-friendly hot process soap. Made with ingredients you already have in your kitchen, this soap is good clean fun!

Ingredients

• 17.65 oz olive oil
• 3.55 oz coconut oil
• 2.85 oz lye (sodium hydroxide)
• 6.9 oz water
• OPTIONAL:
• 0.25 oz lavendar essential oil
• 0.10 oz bergamot essential oil
• 0.10 oz grapefruit essential oil

Instructions

1

Weigh all of your ingredients.

2

Turn crockpot onto low and add coconut and olive oils.

3

While the oil is warming up, add water to a medium-sized glass or ceramic bowl or measuring cup (if it isn't already) and take it outside along with the lye and plastic spoon. 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.

4

Once cool, add lye mixture to your crockpot and stir.

5

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).

6

Cover and cook on low for 45 minutes to an hour. 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.

7

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).

8

Once soap is done, add in essential oils and stir until fully incorporated.

9

Spoon the soap mixture into your mold and let cool for 24 hours.

10

Remove soap from mold and cut into bars.

11

Store in a cool, dry spot (basements are good for this) and allow to cure for 2-3 weeks.

12

Because it is hot process soap, you CAN use a bar right away. Just know it will get better (and harder) over time and be an overall better bar of soap the longer you wait.

Notes

Because the essential oils are added at the very end, it will not effect the outcome if you choose to omit them (or use different ones). According to Mommypotamus, the shelf life of hot process soap is 2+ years when stored in a cool, dry place.
