Aqueous calcium stearate dispersion containing


Aqueous calcium stearate dispersion containing 40 to 55 percent solids is a preferred starting material. Aqueous calcium stearate dispersions are typically prepared by reacting stearic acid with aqueous hydrated lime slurry in the presence of conventional, commercially available dispersing agents, such as polyethoxylated alkyl phenol or dialkyl phenol, e.g., polyethoxylated nonyl phenol or nonyl phenol. Although it is to be understood that the invention is not intended to be limited by any particular method of making an aqueous calcium stearate dispersion suitable for use as a starting material, nor by any specific dispersing agent used to prepare such dispersion, a particularly preferred aqueous calcium stearate dispersion is that made and sold by PPG Industries, Inc. under the trademark, CALSAN.TM. 50. The CALSAN.TM. 50 material contains about 50 weight percent solids, the solids portion of the dispersion comprising about 88 to 90 percent calcium stearate. Starch syrup is commercially obtainable as a concentrated aqueous solution of partial hydrolyzates of starch and typically contains dextrose, maltose, and high oligosaccharides derived from starch by acid or enzyme hydrolysis. Although starch syrup derived from corn starch is preferred for use following the invention, starch syrup derived from other vegetables, e.g., potatoes, may also be used. Starch syrup, suitable for help following the invention, typically has a density range of about 41. degree. To 45. degree. Baume corresponds to a solids content of about 76 to 84 percent weight. Sugar, the common name for sucrose, is a disaccharide compound composed of D-glucose and D-fructose having the formula C.sub.12 H.sub.22 O.sub.11. Sugar is a water-soluble substance that crystallizes in distinctive monoclinic form and occurs naturally in many plants. Commercially, sugar is obtained by evaporation of clarified sugar cane or sugar beet juice.
