Pickering emulsion is an emulsion with colloidal particles instead of surfactant molecules. As early as the beginning of the 20th century, Ramsden had discovered that protein particles could spontaneously assemble at the interface between air and water. Subsequently, Pickering confirmed that water-insoluble colloidal particles can be adsorbed to the oil-water interface and systematically studied the obtained emulsion system, so this emulsion with colloidal particles instead of surfactant molecules was later called Pickering emulsion.

Wanzhao Chemical is made from natural plant raw materials, and is deeply processed by unique physical technology to prepare high-performance colloidal particles. The colloidal particles can be used to prepare Pickering emulsion, which has the following characteristics compared with traditional emulsion:

1.reducing the amount of emulsifier;

2.mild, non-toxic, far less harmful to human body than traditional chemical emulsifier;

3. Friendly to the environment;

4. The emulsion has strong stability and is not easily affected by PH, salt concentration and temperature.

At present, chemical emulsions are widely used in food, cosmetics, pharmaceuticals and other fields. The extensive use of surfactants has an unknowable impact on human health, and this harm can be effectively reduced by replacing the physical emulsification process.
