  • EMULSION OF WATER SOLUBLE DYES IN A LIPOPHILIC CARRIER
    Publication number: 20030046777
    Abstract: The invention herein provides for an improved dye composition for encapsulation in casing structures adapted for projectile motion and rupture upon contact with a target surface, such as paint balls. The dye composition adapted for use in an impact-rupturable capsule of the invention comprises a water-soluble dye and a lipophilic carrier having an oil and an emulsifier, said emulsifier comprising ethoxylated mono- and diglycerides. The invention further provides for an impact-rupturable capsule containing the dye composition. Advantages of the dye composition of the invention include improved consistency and reduced separation of ingredients; greater viscosity and thickness; greater “smearability” and splattering of dye on target surface upon impact and rupture of the casing; and greater water solubility and improved machine washability.
