There is no definitive answer to this question, as the amount of bentonite clay you will need to add to your shaving soap recipe will depend on a number of factors, including the specific recipe you are using and the desired consistency of your finished product. However, as a general rule of thumb, we recommend starting with 1 teaspoon of bentonite clay per pound (or 2 cups) of base oils in your shaving soap recipe. If you find that your soap is too thick or difficult to work with after adding the Bentonite Clay, simply add more oil until it reaches the desired consistency.
For every pound of soap, add 2 ounces of bentonite or other clay. You can use rhassoul or fuller’s earth, but bentonite clay is preferred. It’s a good idea to add a scent or essential oil that’s appropriate for the person shaving.
