ABSTRACT:
Ready-to-use water dispersible pigment compositions containing water-insoluble, hydrophilic pigments are provided. The compositions comprise a stable dispersion of the pigment such as a porphyrin pigment, carmine, curcumin and a caratenoid in the form of bodies of an average size which is at the most 10 μm is provided. The pigment bodies are dispersed without he use of a surface active substance in an aqueous phase comprising a hydrocolloid. The natural pigment compositions which are useful for coloring of food products and pharmaceuticals do not migrate in the products and they are acid stable. The compositions are useful in coating compositions for tables and dragees.
