Classification and preparation of the emulsifying wax have been discussed in the present article. The emulsifying wax is classified into four types of wax such as the cationic emulsified wax, the anionic emulsified wax, the non-ionic emulsifying wax and the amphoteric ionic type emulsified wax based on the properties of surfactant. Further, there are four types of preparation methods for the emulsifying wax are available such as the method of emulsifying agents dissolving in the water, the second in dissolving in the oil, the primary soap method and the taking turns adding method have been introduced also. Effects of the reaction conditions such as choosing the different emulsifying agents, the stirring speed, the emulsifying time and the ratio of emulsifying agents to wax on the emulsifying wax preparation have also been explained.
