The ingredients are mixed together in the weight proportions as shown in Table I to form a concentrate. A small percentage of water is added to the concentrate until a clear solution is attained. Then, the concentrate is added slowly to water with good agitation of the aqueous solution to obtain a 35 weight percent as solids. In approximately /1 hour, excellent emulsion stability is obtained. Each solution is made up to contain 35 percent solids and 65 percent water.

This viscosity is measured in centipoises under standard conditions. An ultralow UL-adapter is employed for the viscosity measurement of emulsions which has its own spindle container and uses a #1 spindle. Since the emulsion and concentrate is Newtonian in character, viscosity can be determined directly at C.
