Abstract:
1. A liquid monoalkanolamide surfactant emulsion useful as an aqueous monoalkanolamide delivery system in a cold mixing process, the liquid monoalkanolamide surfactant emulsion consisting of: (a) a monoalkanolamide, which in unemulsified form is substantially solid and water insoluble at a temperature below about 30° C.; (b) a monoalkanolamide emulsifying effective amount of an amphoteric emulsifying surfactant; and on a total monoalkanolamide surfactant emulsion basis, (c) a water soluble inorganic electrolyte salt present in an amount of not more than about 10 weight percent; (d) a non-surfactant organic solvent present in an amount of not more than about 15 weight percent; (e) an optional fragrance; and (f) the balance being a sufficient amount of water to obtain a total solids content in the range of about 20 to about 60 weight percent; wherein the liquid monoalkanolamide surfactant emulsion is cold mixable into a separately prepared liquid aqueous formulation containing at least one principal surfactant to form a finished product, and is phase stable and pumpable at a temperature in the range of about zero to about 30° C.
