The principle of silicone oil emulsion is based on emulsification technology. By combining silicone oil with appropriate emulsifiers, it can be miscible with water and form a milky liquid. The following are the principle steps of silicone oil emulsion:

1. Emulsifier selection: Choosing a suitable emulsifier is a key step. Common emulsifiers include surfactants, surfactants or colloidal substances, which have hydrophilic and hydrophobic parts that can reduce the surface tension between liquids and promote the emulsification process.

2. Prepare emulsion: Mix silicone oil and emulsifier in a certain proportion, and emulsify through mechanical stirring or ultrasonic treatment, so that the silicone oil is finely dispersed in the water phase to form a milky liquid.

3. Stable emulsion: The function of emulsifier is to reduce the surface tension between liquids and avoid the aggregation and separation of droplets. During the emulsification process, the concentration of the emulsifier and the emulsification time must be controlled to obtain a stable emulsion liquid.

4. Application emulsion: Stable silicone oil emulsion can be directly used in areas that require lubrication, anti-adhesion, anti-corrosion and other functions. Depending on specific needs, different emulsion formulas and concentrations can be selected.
