The process of forming an emulsion is called emulsification. In this process, one immiscible liquid is dispersed in another immiscible liquid. Therefore, we can say that the recombination of two immiscible liquids is called emulsification. For example, creams used in the cosmetic industry are formed by emulsifying oil in an aqueous medium.
Microemulsions have particle diameters of only 400 – 600 nm. Now many ointments are used for the treatment of many diseases, which is the effect of emulsification. These emulsion oil droplets are formed using an emulsifying machine and are delicate and easy to absorb.
Because of the small diameter of the emulsified particles, they increase surface tension and are strongly attracted to other lipids, causing them to coalesce. If these droplets fuse with the bacterial or viral membrane in large numbers, it will cause the membrane to rupture, effectively killing the bacteria/virus. This is of great help to the pharmaceutical industry.
