Abstract
Abstract Water soluble coloring compositions are provided that contain a stable and uniform suspension of color and sparkle or glitter components. The process for producing the coloring compositions employs a lower temperature range than the prior art; this reduces the need for equipment heating and enables the equipment to be more readily cleaned.
