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 μm 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.
Claims20
A ready-to-use water dispersible pigment composition that contains in excess of 10% by weight of water, the composition comprising a dispersion of a water-insoluble and/or hydrophobic natural pigment in the form of bodies of an average size which is at the most 10 μm, said bodies being dispersed in the absence of a surface active substance in an aqueous phase comprising a hydrocolloid in an amount of at least 1% by weight of the pigment, the composition, when it is added to a food product or a pharmaceutical product comprising multiple, separated compartments, whereby the composition is dispersed in one or more selected compartments, essentially does not migrate from said compartment(s) where it is dispersed into other compartments.
A method for administering a ready-to-use water dispersible pigment composition comprising dispersing a water dispersible pigment in the aqueous phase of an edible product, wherein said dispersible pigment contains in excess of 10% by weight of water, and comprises a dispersion of a water-insoluble and/or hydrophobic natural pigment in the form of bodies of an average size which is at the most 10 μm, said bodies being dispersed in the absence of a surface active substance in an aqueous phase comprising a hydrocolloid in an amount of at least 1% by weight of the pigment.
A method for manufacturing a pharmaceutical product comprising,
- dispersing a ready-to-use water dispersible pigment, in the absence of a surface active substance, into an aqueous phase of said pharmaceutical product, wherein said ready-to-use water dispersible pigment contains in excess of 10% by weight of water, wherein the ready-to-use water dispersible pigment comprises a dispersion of a water-insoluble and/or hydrophobic natural pigment in the form of bodies of an average size which is at the most 10 μm, wherein said bodies are dispersed, in the absence of a surface active substance, and wherein said aqueous phase comprises a hydrocolloid in an amount of at least 1% by weight of the pigment.
