Note: If you want to use a melt and pour base to make a shaving soap, check out my Melt and Pour Shaving Soap recipe.
To modify your own recipe, just take your basic soap recipe and add about 2 tsp. of Bentonite or other clay for every pound of soap in the batch. I prefer Bentonite clay, though you can use Kaolin, Rhassoul or Fuller's Earth. (Click here to buy clays direct or look at the links on the right for more information about clays.) The recipe below makes about 3 lbs. of soap, so I'm using 2 tbs. of clay. Up your percentage of castor oil to about 8%. That's it. Add a fragrance or essential oil appropriate for the person shaving - but be sure that it is one suitable for sensitive skin - remember, you're shaving through this soap.
The recipe I use is:
- 40% Olive oil - stable lather and good skin conditioning
- 30% Coconut oil - rich, bubbly lather
- 22% Palm oil - stable, creamy, hard bar (can substitute lard or tallow)
- 8% Castor oil - for lather and creaminess
- 13 oz. Olive oil
- 10 oz. Coconut oil
- 7 oz. Palm oil
- 2.5 oz. Castor oil
- 4.7 oz. Lye (about a 5% discount)
- 9.4 oz. water
- 2 Tbs. of Bentonite Clay
- 1 to 1.4 oz. of fragrance or essential oil
I like to pour the soap directly into coffee mugs or tins. Another option is to pour it into lengths of 3" PVC pipe that has one end plugged up. This will give you a disc of soap that can be placed into a mug or tin. Let the soap cure as normal, and when it's done, enjoy a wonderfully old-fashioned but terrific shaving soap!
