Abstract

The invention discloses a high internal phase emulsion stabilized by using a low-content surfactant, and a preparation method of the high internal phase emulsion. The preparation method comprises thefollowing steps: adding a grease ethoxylate into vegetable oil, and performing low-speed stirring and uniform mixing at room temperature; dropwise adding water into the mixture of the surfactant and vegetable oil while stirring; and homogenizing the obtained dispersion system by using a high-shear dispersion emulsification homogenizer to obtain the high internal phase emulsion stabilized by the grease ethoxylate. The preparation method of the high internal phase emulsion has the advantages of low surfactant consumption, mild preparation conditions, and simple and convenient operations. When avolume fraction of an oil phase is 83 vol%, a minimum mass fraction of the high internal phase emulsion stabilized by the grease ethoxylate is 0.6 wt%. The prepared oil-in-water high internal phase emulsion has excellent stability, is bright in color, light in smell, very moist in touch feeling, and easy to smear, and greatly widens the application prospect of the high internal phase emulsion in personal care.

Description

technical field [0001] The invention relates to the field of high internal phase emulsion preparation technology development, and more specifically relates to a stable high internal phase emulsion using a very small amount of surfactant and a preparation method thereof. Background technique [0002] High internal phase emulsion (HIPE) has a wide range of applications in food, biomedicine and materials. It is usually defined as an emulsion with an internal phase volume fraction greater than 74.04%. When the volume fraction of the internal phase is less than 74%, the dispersed phase still maintains a complete spherical shape; if the volume fraction of the dispersed phase continues to increase until it reaches 74.04%, the droplets of the dispersed phase are closely packed and interconnected but the droplets do not deform; further increase the volume fraction of the dispersed phase When the volume fraction exceeds 74.04%, the droplets are squeezed against each other, separated ...
