ABSTRACT:
An HIPR emulsion of oil in water is prepared by a method comprising the steps of (a) generating a foam by beating a gas into an aqueous solution of a surfactant and (b) dispersing the foam into the oil under low shear conditions in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising distorted oil droplets having mean droplet diameters in the range 2 to 50 microns, separated by aqueous films, 70 to 98% by volume of the liquid content of the emulsion being oil.
The method is applicable to both high and low viscosity oils.
Depending on the nature of the oil, the emulsions can be used in the food, drug, cosmetics and petroleum industries.
