Abstract:

For preparing O/W miniemulsions containing soybean oil and silicone oil, three methods, phase inversion emulsification, D-phase emulsification, reformed D-phase emulsification were tested by using Brij92, 97, 98 and Tween 80, 85, 60, 20 and Span 80, 60 mixed surfactants. It was found that the O/W miniemulsions of soybean oil and silicone oil can not be formed by phase inversion emulsification method, but can be formed by the two other methods. The results of emulsification showed that if gel emulsion, in which fine oil droplets disperse in continuous phase with high surfactant content, appears during the emulsification process, the O/W miniemulsions can be formed by simply diluting with water.
