Abstract
The present invention relates to a dry mixture which provides a color-stable liquid composition when combined with free chlorine-containing water, said dry mixture comprising: (a) from about 0.005% to about 0.035% by weight chlorine reactive agent; (b) from about 0.5% to about 5.0% by weight electrolyte; (c) coloring agent, wherein the dry mixture comprises sufficient coloring agent to provide for a concentration of coloring agent in the range of from about 5 ppm to about 200 ppm in a color-stable liquid composition prepared from said dry mixture; and (d) a balance of carbohydrate. The present invention also relates to a method of preparing a color-stable liquid composition, said method comprising: (a) preparing a dry mixture comprising: (1) from about 0.005% to about 0.035% by weight chlorine reactive agent; (2) from about 0.5% to about 5.0% by weight electrolyte; (3) coloring agent, wherein the dry mixture comprises sufficient coloring agent to provide for a concentration of coloring agent in the range of from about 5 ppm to about 200 ppm in the color-stable liquid composition; and (4) a balance of carbohydrate; and (b) combining said dry mixture with free chlorine-containing water, thereby producing a color-stable liquid composition; wherein the weight ratio of water combined with dry mixture is in the range of from about 10.5:1 to about 22:1 (water:dry mixture), wherein the molar ratio of chlorine reactive agent contained in the dry mixture to free chlorine contained in the water is at least about 2.2:1 (chlorine reactive agent:free chlorine), and wherein the color-stable liquid composition comprises from about 5 ppm to about 200 ppm coloring agent.
