FD&C colourants (Food, Drug and Cosmetics) are colour additives which are soluble (dissolve) in water, oils, alcohol or glycerin. They produce very bright, intense colours, but they do bleed/migrate in soap and they are usually unstable in cp soap. They are generally inexpensive to use as they are extremely concentrated and they mix in smoothly so are easy to use.

I only have a small selection at present but I will eventually stock all the dyes in both powder and liquid form.
