Abstract
A considerable amount of energy which is normally wasted in the commercial processing of cosmetic and pharmaceutical emulsions can be saved by using Low-Energy Emulsification (LEE) technique proposed by Lin (1). When correctly executed, the quality of emulsion prepared by LEE is virtually indistinguishable from that of emulsions manufactured by the conventional hot method (2).By supplying energy only when and where it is needed, LEE often allows conservation of over 50% of the thermal energy normally expended in commercial processing. LEE application in high α range can, sometimes, completely eliminate the necessity for the time-consuming cooling operation and result in an increase of production efficiency of over 100% (3).Further research on LEE revealed that one of the key variables which significantly affects the emulsion quality is the emulsification temperature as well as the temperature of the concentrate prior to simultaneous dilution and cooling. In some systems, a higher temperature favors formation of fine droplets; whereas in others, the opposite may be true. By a careful control of the temperature through the use of solubilization chart, the mean diameter of the emulsion droplets can be controlled to produce desired emulsion.The result of this finding can be applied to manufacturing fine cosmetic emulsions with very little energy consumption and greatly improved efficiency
