Water based FD & C color additive for natural soaps, lotions and creams. Various shades of color can be achieved by the amount of color you add from a very soft, pale shades of turquoise blue to a deeper, rich Caribbean blue color. We love pairing this color with peppermint oil! 30 ml bottle. Ships in powder form in a bottle. Simply add water when ready to use. Hydrates to a 2 oz. bottle of color. We recommend 1/4 teaspoon per 3 pounds of soap.
