Though still a definite red, this iron oxide has a slight "brown" tone to it giving it a warm "terra cotta" color to finished soaps.
To use, simply add drop by drop to your melted melt & pour soap base, or other beauty care recipe, and stir until the color depth has been achieved.
For water soluble recipes only.
INCI: Iron oxide (and) 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.
