Iron Oxides: "Iron oxide materials yield pigments that are nontoxic, nonbleeding, weather resistant, and lightfast. Natural iron oxides include a combination of one or more ferrous or ferric oxides, and impurities, such as manganese, clay, or organics. Synthetic iron oxides can be produced in various ways, including thermal decomposition of iron salts, such as ferrous sulfate, to produce reds; precipitation to produce yellows, reds, browns, and blacks - USGS 2004 "

We do not use synthetic version of Iron Oxides in our mineral makeup.

Though claimed to be "all natural", Iron Oxides go through extensive treatment in labs in order to purify and or remove certain metals that can be harmful to humans, thus simply making them as natural as it gets without compromising your health.
