Water based food grade colorant. Great for melt and pour soaps, washes, bubble bath, lotions. These liquid colors are not recommended for cold process soaps since they tend to morph into other colors. If you want to use them in cold process soap make sure to do a small test batch to see results.
Gel Colors are much like the liquid colorants, much more intense color. Good for lotions, body wash, bubble bath, bath bombs. Not recommended for use in salts, the liquid colorant is much better for salts. Easier to use in cold process soaps but they may still morph in color.
