Sea Salt and Bentonite Clay Soap

My newest soap! This is sea salt soap, also known as spa bars. It is made very differently than your regular cold processed soaps with 80% coconut oil, 20% super fat, and salt as much as 50-100% of oil weight. The salt can be a gentle exfoliator, adding trace minerals to the skin and rejuvenating dry skin or controlling oily skin. I also added some bentonite clay to this soap for extra soothing qualities. Supposedly this soap will be great for all types of skin and can help reduce acne. I plan to try it first as a face wash soap.

When I created this recipe I had to do things a little differently. I knew I wanted to use 80% coconut oil. This is because salt can kill lather and coconut oil is known for its lathering abilities. However, coconut oil can also be drying to the skin. This is why I did a 20% superfat in the recipe. This means that 20% of the oils in the recipe will not react with the lye and will be very conditioning and nourishing to the skin. I decided to use some tallow, olive and castor oil to round out the mix.

For the salt I decided to use 75% of oil weight. So, for 16 oz of oils I used 12 oz of salt.

Sea Salt and Bentonite Clay Soap

80% Coconut oil

10% Tallow

5% Olive oil

5% Castor Oil

Essential oils:

4 g Lavender EO

5 g Lemongrass EO

4 g Rosemary EO

4 g Peppermint EO

1 Tbsp bentonite clay

1/4 tsp of green oxide pigment

12 oz salt (I used fine grain sea salt, but you can use any salt you like. Just don’t use dead sea salt because the magnesium in the salt will cause your soap to become weepy and fall apart).

Run oil amounts through Soapcalc to figure out your final amounts of lye, water and oils. Measure out your fragrances and any other additives.

Measure out your lye and add it to your water. In a heavy bottom pan or pot measure out your oils and melt them over low heat. Once your lye solution and oils are about the same temperature add them together and blend with an immersion blender until they reach a light trace. Add in bentonite clay, pigment and essential oil blend and blend some more with the immersion blender until everything is incorporated really well. Then mix in the salt and immediately pour into molds. I used a silicone mold for this, but I have heard that if you use a loaf mold that you need to cut it while it is still warm, as soon as a few hours after molding because it hardens really quickly. If you wait too long then it becomes too hard to cut and crumbles.

I have all four batches of soap curing. Now I just need to figure out where I am going to store all of my soap until it is ready to be used…

    1. Hello, If you don’t want to use tallow you could use any other type of animal fat like lard (from pigs). However, if you wanted a vegan/vegetarian alternative to tallow then you can use palm oil. You just want to research the source you are getting it from because there are a lot of sustainability issues with harvesting palm oil. Thanks!
