When the emulsification process is carried out in the emulsifier, the choice of emulsification equipment and emulsifier will directly affect the emulsification result of the material.
We all know that the emulsification equipment that completes the two-phase mixing of water and oil in the emulsification machine is an emulsification machine. The emulsification machine is a general term for emulsification equipment. There are many types of emulsification machines. Colloid mill and homogenizer. They are all equipment for emulsification, but they have their own characteristics and advantages. This requires us to choose emulsification equipment according to our own emulsification materials and the requirements we want to achieve. Because different emulsifiers have different structures, performances, and the quality of the substances of the formed milky liquid.
For example, for our commonly used cosmetics, we choose a stirring emulsifier in the production process, because it is not only easy to manufacture, but also cheap, and its reasonable structure is enough to complete the emulsification of materials. But if the desired emulsion is better, then the editor recommends that you choose the other two, because the dispersion and stability of the emulsion produced by them are very good.
In addition to the choice of emulsifiers, there is one more thing we need to choose during the emulsification process, and that is the emulsifier, which is a surfactant that helps form a relatively stable emulsion during the emulsification process.
When choosing, there are several points worth noting: we should choose an emulsifier similar to the hydrophobic base and the substance to be emulsified, and the selected emulsifier should be easy to dissolve. You can also choose several emulsifiers to mix For use, generally we suggest that you can choose a better hydrophilic emulsifier and a better lipophilic emulsifier for mixed use. In addition, water-soluble emulsifiers are mainly used to prepare O/W liquids, and the dosage of other emulsifiers is multiplied and decreased on both sides of the main emulsifier according to the HLB order. The HLB value of the composite emulsifier should be roughly the same as the emulsified oily substance.
