Soap Making Colorants—which one to choose?
There are several different soap colorant options that are available for soap makers.
Natural soap colorants are more favored by expert soap makers as it is much safer to use. You can get amazing results with natural dyes and you don’t need to go the synthetic route to get soap that people buy. The best soap making advice I can give you is to try the natural dyes and see how things turn out. Of course you’ll need some practice but this is part of the learning process when you make your own soap.
For example, saffron can give your soap a yellowish glow, indigo root can be used to give your soap a deep blue color and Moroccan red clay can be used to give your soap a brick red color.
If you prefer using synthetic soap colorants, there are a variety of choices that can be used. By way of comparison, they are easier to use than many natural soap making colorants and provide a much wider range of colors.
FD&C colorants are colors made in the laboratories, usually mass produced and as a result, more inexpensive than the natural colorants for soap making.
It is more popularly used in the food industry but this can also be used in coloring your soap.
FD&C colorants are used in many processed food.
These colorants are available in a wide range of colors and can come in both liquid and powder form.
They are mainly used in Melt and Pour soap making and don’t usually remain stable in Cold Process soap due to its high alkalinity. (Learn more about the different soap making methods here).
In addition to the natural and FD&C colorants, you can also use micas.
Micas are a combination of synthetic and natural materials. Shimmery micas are usually used for cosmetics, but it also can be used for soaps especially if you want your soap to have a little glittery effect on them.
This soap making colorant is best used in translucent soaps.

Some colorants, even if they’re natural, are irritating to the skin. It is also a good idea to mix and match colorants first to see if it is just the right amount of concentration you want on your soap.
