What is covered in “Coloring Soap Naturally”?
Ruth tested 34 different ingredients that can be used to color cold process soap. They were added at trace, in the lye and as an oil infusion. Plus, some of the soap was allowed to go through a gel phase, and some was not. All of the results and photos of these tests are included in “Coloring Soap Naturally”. You’ll also find a list of the suppliers that were used for the colorants, and a chart of the colorants by color, so you can find the one you’re looking for quickly. In addition, Ruth describes how she tested everything, so that you can use the same procedures to test any other ingredient that might interest you. You can see the Table of Contents in a photo at the top of the page.
Which colorants do you consider “natural” and which did you test in your book?
In talking about soap and cosmetics, there is no official definition of “natural”. When deciding on which ingredients to test for my book, Ruth considered “natural” to be something that is minimally processed (like dried, cut, or ground) but not synthetic. So no pigments, micas or dyes. “Coloring Soap Naturally” is about only natural colorants: plants, herbs, clays, etc. You can see a list of the ingredients tested in a photo at the top of the page.
What kind of information do you give for each colorant?
Each of the 34 colorants has its own page that lists information about the ingredient, what source I used, how much was used in my tests, and photos of the results. You can see a sample page in a photo at the top of the page.
