Abstract:
A method for controlling emulsion particle size and emulsion particle size stability, the method comprising:forming a mixture by combining an emulsion particle size stabilizing effective amount of a lipophilic-fluorophilic compound, a surfactant, an aqueous continuous phase and perfluorooctyl bromide, said lipophilic-fluorophilic compound of the formula: CF3(CF2)tâ€”(CH&boxH;CH)yâ€”(CH2)vâ€”CH3; orCF3(CF2)tâ€”CH2)yâ€”CH3; â€ƒwherein: t=2 to 11; y=0 to 6; v=1 to 15; and emulsifying the mixture.
