What’s the difference between organic and inorganic pigments?

An inorganic pigment is a dye substance which does not contain carbon, except in its elementary form (carbon black – carbonate) or carbonate. They include mainly oxides, salts or silicates. They can be obtained from finely pulverized minerals or chemical synthesis. They are composed of other elements such as iron, aluminium, cobalt, or chromium.
Natural organic colourants are not used for PMU pigments because these powders are very expensive and not insoluble, with scarce availability.
Organic pigments are very shiny but more expensive and last for less time on the skin, whereas inorganic pigments last longer (like some of the most dangerous / non approved organic dyes).
“Organic” pigments DO NOT come from organic natural sources. On the contrary, they are the result of chemical synthesis. In our common understanding an organic product is one from natural sources, but the reality is different.
Organic and inorganic dyes can be mixed.
