With this iron oxide, you can easily tone your melt & pour soaps a stunning mustard to light yellow. Simply add drop by drop and stir until you have achieved the desired color depth. Will work in any formulation that is water soluble.
We also sell a powder version of this colorant if you wish to work with it in that form.
INCI: Iron oxide & organic glycerin (Yes! We use organic glycerin to manufacture these colorants, though the iron oxides cannot be certified organic ... see below).
Please note that our iron oxides are a high quality, lab produced, synthetic colorant. They are globally compliant to be used in cosmetics sold internationally.
Iron oxides can be found in nature, but they are generally not safe nor approved for cosmetic use, as they often contain high levels of lead and other toxic heavy metals. Any website that claims they are selling a natural iron oxide (and not a lab produced version as ours is), should be carefully evaluated.
