The discussion of the emulsion is of great importance for the study and production of cosmetics, and the preservation and use of cosmetics.. After determining the reasonable formulation of the high shear emulsifying machine, the emulsification technology is also very important.. The preparation of cosmetics is mainly mixed technology. Although high shear emulsifying machine mixing technology is relatively simple, but as a cosmetic, requires a variety of functions and properties, to prepare excellent properties and stability of the emulsion cosmetics, is not a simple matter.
Emulsification is a kind of liquid in the very small droplets evenly dispersed in the mutual non phase of the role of another liquid. The emulsion is liquid liquid interface phenomenon, two kinds of insoluble liquid, such as oil and water, in the container into two layers, the density of small oil in the upper, the density of the water in the lower layer. If the appropriate surfactant is strongly stirred, the oil is dispersed in the water, and the emulsion is called an emulsion.
