Method for preparing an emulsion with high-viscosity organic phase |
摘要 |
The invention concerns a method for preparing an oil-in-water emulsion whereof the organic phase has a viscosity not less than 1 Pa.s, which consists in using an aqueous phase comprising at least a heat-thickening polymer having a viscosity jump between 25 and 80° C. so that the value of the ratio log 10 (viscosity at 80° C.)/log 10 (viscosity at 25° C.) is at least equal to 1, preferably at least equal to 2, the variation in viscosity being reversible; the amount of heat-thickening polymer being such that the aqueous phase viscosity is 0.2 to 5 times that of the organic phase at the temperature for preparing the emulsion; the latter being not less than the thickening temperature of the heat-thickening polymer. |
