  • Water dispersible compositions containing natural hydrophilic water-insoluble pigments, methods of preparing same and their use
    Patent number: 7229490
    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 ?m 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.
    Type: Grant

  • Water dispersible compositions containing natural hydrophobic pigment, method of preparing same and their use
    Patent number: 6190686
    Abstract: A ready-to-use water dispersible pigment composition containing at least 5% by weight of water is provided. The composition comprises a stable dispersion of a water-insoluble and/or hydrophobic natural pigment such as a carotenoid, curcumin, a porphyrin pigment or vegetables carbon black in the form of bodies of an average size which is at the most 10 &mgr;m is provided. The pigment bodies are dispersed without the use of a surface active substance in an aqueous phase comprising a hydrocolloid. The natural pigment in compositions which are useful for coloring of food products and pharmaceuticals do not migrate in the products. The compositions are useful in coating compositions for tablets and dragees.
