Highly concentrated D&C grade (drug & cosmetic) dyes are great for melt & pour soaps and lotion/gel bases too. Each dye comes in our 1 oz. dropper top bottle so it's easy to measure the amount of dye that you are using. 1 oz. Bright Yellow soap dye (D&C #5).
Liquid soap dyes are water soluble therefore should NOT to be used in Cold or Hot Process soaps.
