低温乳化技术

表面活性剂＝含有亲水基和疏水基的化学品
Surfactant = chemical component with hydrophilic and hydrophobic group

表面活性剂使两相有机地结合起来，形成一个整体
Surfactants concentrate at the interface between 2 phases creating an organic film

链的长度可以调节小滴的弯曲度
The length of the chain allow to adjust the curvature of the droplets

表面活性剂使乳剂稳定
Surfactants allow the stability of an emulsion

Internal phase 内相= the dispersed phase 分散相
External phase 外相= the continuous phase 连续相

混合得越均匀，小滴越小，那么乳剂就越稳定
The smaller and more homogeneous the droplets are, the more stable is the emulsion
