ABSTRACT:
A pharmaceutical tablet consists of a substrate containing a medicament and may be covered with a coating, said coating including a pigment comprising a natural water insoluble edible powder dyed with an edible natural dye. The pigment for coloring the tablet, or other pharmaceutical products, as well as food and cosmetics, is made by suspending a natural water insoluble edible powdered substrate in an aqueous vehicle and dyeing the suspended powdered substrate with an edible natural dye. The liquid is removed to obtain the dry pigment powder of the invention which then can be suspended in a suspending medium and used for coating products to be colored such as food, drug and cosmetic products.
