Properties

Because of the very small amount needed, the marker does not influence the physical and chemical properties of the original product. A plastic for instance contains only a few ppm of marker which is clearly less than for example the amount of pigments used for coloring.

The markers are completely insoluble and nontoxic. They therefore comply with the requirements of FDA (US Food and Drug Administration) and are thus applicable to medical devices and products that come into contact with drinking water and food.
