Sandalwood with Bentonite Clay Soap Recipe

My Sandalwood bar is always a best seller among men and women alike. This was actually the first of my handmade soaps that my husband would try, after I had been making soap for over a year and now it’s the only soap he uses. The man is as picky as they come so it’s a huge compliment that he loves it so much. The intoxicating scent of Sandalwood is what drew him in and the effects of the Bentonite Clay on his skin keep him using it day after day. It’s a great shower bar.

The Bentonite Clay has a drawing effect to help remove toxins and impurities from the skin, especially heavy metals. It has been shown to neutralize bacteria and is loaded with minerals including calcium, magnesium, sodium, potassium, silica, copper, and iron. It can ease the symptoms of Psoriasis, Eczema, and rashes associated with Poison Ivy, Poison Oak, and Poison Sumac.

The benefits of the Bentonite Clay extend well beyond what I listed so it would make sense to use it in soap.

As an added bonus, it also helps to “anchor” the sandalwood scent to the bar and prevent it from fading.

I joke that it’s part of my private reserve because it sells so fast among my friends and family that I can’t stock it in any stores. Not a bad problem to have I guess.

Here’s how it’s made. As always, please use proper protective safety gear!


  • 9.6oz (30%) Coconut Oil
  • 9.6oz (30%) Olive Oil
  • 9.6oz (30%) Palm Oil
  • 3.2oz (10%) Castor Oil
  • 4.59oz Sodium Hydroxide
  • 10.56oz Water
  • 1oz Sensuous Sandalwood Fragrance Oil – I get mine from Brambleberry.
  • 2 Teaspoons Bentonite Clay

Anchoring the Scent

Any soap that has clay in the recipe, I always add the essential oils or fragrance oils directly to the clay. The clay absorbs the scent of the oils and gets evenly mixed so I don’t end up with little dry clumps of clay in the soap batter.

Step 1: Put the 2 Teaspoons of Bentonite Clay into a container. Since the clay acts like a magnet for heavy metals, it may react with metal utensils so be sure to use a plastic or silicone spoon.

Step 2: Weigh 1oz of Sandalwood Fragrance Oil.

Step 3: Add the Sandalwood Fragrance Oil into the container of Bentonite Clay and mix well until all the dry clay is wet.

The clay will sink to the bottom and settle so it will need to be mixed well again before adding to the rest of the soap batter.

Preparing the Soap Batter

Combine Sodium Hydroxide and water and allow to cool to about 110°. I like to put my container of lye water into an ice bath in the sink to bring the temperature down more quickly.

Combine Coconut Oil, Olive Oil, Palm Oil, and Castor Oil. I put them all into a bucket and microwave then for a couple minutes to turn them all into a liquid state and get them close to 110° also. The lye solution cools down much faster than the heated oils so be careful not to overheat the oils or you’ll be waiting forever for them to cool down.

Add lye solution to the oils once cooled and stick blend to light trace.

Add Bentonite Clay/Fragrance Oil Mixture. Scrape out any residual Bentonite clay into the soap batter. You don’t want to lose any of that skin loving goodness. Mix well by hand.

The mom juice in the background is not part of the recipe.
This is what it looks like all mixed.

Then I just pour it into my mold and insulate with towels since I use a wooden mold.

That’s it. It’s a really simple recipe that packs a major punch. The soap itself takes on a slight grayish green once cured.

I’d love to hear your feedback in the comments below!

  1. Hi! After you add the clay mixture the directions say to mix well by hand, but the picture shows a stick blender! Is it okay to use a stick blender in that phase??

    1. Hi! You can definitely use your stick blender here! I just like to mix by hand to keep it from getting too thick so I can still pour it into the mold easily.
