The Wonderful World of Soap Colorants
Color, color, color! Although I know that some of you prefer not to add color to your soaps, a great many of you wouldn’t make a batch without. Why is that? Is a soap not as good uncolored as it is colored? Of course it is! A soap’s performance is not dependent upon color; however, our desire to add color is still important to us and often, to our customers or the recipients of our gifts.
As many soap artisans are truly artists, the appeal of color and design is just too important to bypass and half the fun of making soap is creating colorful designs. Nevertheless, color isn’t important only to the more fanciful among us, but even to those of us who make simpler, one-colored soaps or other not-so-fancy soaps. If we’re making soap that smells like the ocean for instance, we want color that is reminiscent of the ocean, and it makes sense that a rosemary mint soap be green. Moreover, we want our orange scented soap to be. . . well, orange.
Even still, many of us are still confused by color. We don’t know which colorants to use or how to use them properly. Our colors morph or speckle or disappear. How do these soapmakers do it, we ask? Seeing the beautifully swirled and otherwise colored soaps of our sisters and brothers in the soaping world, we know it can be done, but how?
I can’t do the topic justice in just a blog post, but the most common colorants for soap are:
1. Herbs and spices (and other natural sources of color)
2. Ultramarines & oxides
Which one(s) you choose depend upon a few different factors, such as the kind of soap you’re making. Some colorants that work well in melt and pour soap do not work well under the high pH of cold or hot process soap. Sometimes, for the effect we want, a bleeding colorant will add to the design; other times, a non-bleeding colorant is imperative. A number of soapmakers want to use only natural colorants obtained by infusing or powdering herbs, spices and other naturally-derived agents, whether for their properties in the soap for strictly for color.
Your first task is to decide what is important to you when choosing colorants. If bright colors and crisp designs are at the top of your priority list, for instance, choose ultramarines and oxides or micas. If your desire is beautiful coloring that is easily mixed into the soap, and you’re making a once-color batch or you want your colors to blend a bit, then FD&C colors are just fine. If you’re looking for natural colorants, it’s herbs, spices, etc. Once you decide, you can purchase your colorants and you’re on your way to making colorful soaps.
In my next post, I’ll go into more detail about natural colorants.
