A method for obtaining a betalain pigment composition from red beet plants comprising pre-harvest foliar spraying of an ethylene-generating compound and the use of the obtained betalain pigment composition for coloring of an edible product.

The present disclosure is drawn to aqueous pigment co-dispersions. The co-dispersions include self-dispersed pigment with a chemically modified surface; released surface moieties from the self-dispersing pigment; pigment powder having the released surface moieties associated with pigment powder surfaces; polymeric dispersant; and water.

The present invention is directed to a novel, low-toxicity red smoke generating composition and a method of making the same, comprising at least one red dye, a coolant, an oxidizer, a non-sugar binder, and a non-sulfur particulate fuel that is also a burn-control agent having at least one particle size distribution. Preferably, the red dye comprises an anthracene or anthraquinone-based dye and the fuel comprises a sugar or mixture of sugars.

The present invention relates to a laundry detergent composition comprising a particle comprising hueing agent and clay. The particle can be incorporated into laundry detergent products, such as a laundry detergent powder. The particle exhibits an excellent storage stability profile with very little bleeding of the hueing dye from the particle, exhibits excellent fabric deposition of the hueing dye during a laundering process without causing any spot staining of the fabric, and does not impact the visual appearance of a laundry detergent powder when incorporated therein.

A dry dye pad for dyeing fishing lures can include: a dye; and a substrate comprising polymer particles suspended in a liquid plasticizer, wherein the substrate forms a permanently plasticized solid after heating and cooling. The substrate can be a plastisol. The plastisol can be heated and cooled to form the dye pad with the dye. The fishing lure can be dyed by contacting at least a portion of the fishing lure to a surface of the dry dye pad. The fishing lure can be dyed in as little as 1 to 3 seconds. The dry dye will not stain a user's skin. A stencil can be placed over the surface of the dry dye pad to create a dyed pattern on the fishing lure. The lure can be dyed with more than one color and patterns to create a lure that resembles bait or prey for fishing.

A quinacridone solid solution pigment that allows a colored product to have high chroma and a properly yellowish hue and has a controlled particle diameter, and a method for producing the quinacridone solid solution pigment. In the method, a water-containing crude quinacridone solid solution is produced by a co-cyclization reaction of a diarylaminoterepththalic acid and a dialkylarylaminoterephthalic acid in polyphosphoric acid, then the resulting water-containing crude quinacridone solid solution having a mass ratio of unsubstituted quinacridone to a 2,9-dialkylquinacridone of 85:15 to 60:40 is dried, thereby obtaining a powdery, crude quinacridone solid solution having a water content of less than 1%. Then, the resulting powdery, crude quinacridone solid solution is heated in a liquid medium that does not dissolve the crude quinacridone solid solution. Also, a pigment dispersion liquid and an inkjet ink each containing the obtained quinacridone solid solution pigment are provided.

The present invention provides a method for preparing a colour-stable preparation of a magnesium chlorophyllin alkali metal salt or alkali earth metal salt from natural sources of chlorophyll. The invention further provides a colour-stable and substantially pure pigment composition comprising a vibrant green magnesium chlorophyllin in the form of an alkali metal or alkali earth metal salt, e.g. those prepared by the methods of the invention, and the use of the salts and compositions of the invention as colouring agents, in particular as food colouring agents, and as medicaments and disinfectants.

An object of the present invention is to provide a phycocyanin pigment composition insoluble in water and provide food, cosmetics, a coating material or a printing marker for pharmaceuticals or agricultural chemicals, a stationery product, a writing tool, a printing ink, an inkjet ink, a metal ink, a paint, a plastic coloring agent, a color toner, a fluorescent labeling agent, a fluorescent probe, or a chemical sensor, each containing the pigment composition. It was found that the phycocyanin pigment composition containing phycocyanin and a metal or a metal compound was insoluble in water, and thus the present invention was accomplished.

This invention relates to non-bleeding, non-staining occult particles for use in granular or powdered laundry care compositions such as laundry detergents, laundry aids, and fabric care compositions. The occult particles are comprised of a clay carrier and a coloring agent and are characterized as being substantially indiscernible when contained in the laundry care composition.

The present invention provides a method for preparing a colour-stable preparation of a magnesium chlorophyllin alkali metal salt or alkali earth metal salt from natural sources of chlorophyll. The invention further provides a colour-stable and substantially pure pigment composition comprising a vibrant green magnesium chlorophyllin in the form of an alkali metal or alkali earth metal salt, e.g. those prepared by the methods of the invention, and the use of the salts and compositions of the invention as colouring agents, in particular as food colouring agents, and as medicaments and disinfectants.
