Wool Wax Emulsions

Emulsions prepared with a wool wax isolate and its ethoxylated derivative have been formulated and studied. Rheological patterns were determined over a 12-month period and flow types characterized. Globular sizes were also determined and correlated with the observed stabilities (creaming rates) and emulgent concentrations. The inapplicability of Stokes' law in theoretical calculations of creaming rate has been shown. A stable emulsion may be produced by selecting as an emulsifying agent a material that will not form a true solution with either of the emulsion phases while exhibiting an affinity for or a greater solubility (colloidal sol) in the external phase.
