Black Oxide 1 oz.
INCI: Iron oxide.
Cosmetic grade pigment.
FDA approved for use on skin, lips, eyes, face and nails.
Available in powder form.
Mixing suggestion: Start with a bit of the colorant and slowly add your chosen medium to the colorant until you get the consistency you want. Once you have the desired consistency, incorporate the colored medium into the base you're working with. This process will minimize speckling and clumping.
Recommended medium for dispersion is glycerin, fragrance oil, or an ingredient oil in the soaps you're making.
