The trend of surfactant's steady growth in the world provides a good external environment for the development and expansion of cosmetics industry, and the requirements for product structure, variety, performance and technology are also higher and higher. Therefore, it is necessary to systematically develop safe, mild, biodegradable and special surfactants, provide theoretical basis for the development and application of new products, focus on the development of glycoside surfactants, which can develop a variety of polyols and alcohol surfactants, systematically research and develop soybean phospholipid surfactants, develop sucrose fatty acid ester series products, and strengthen the compound technology In order to reduce the harm of chemical composition to human body, it is believed that the development of environmental friendly surfactants will greatly promote the development of functional cosmetics.

With the continuous development of biotechnology, the basic research of bacteria and surfactants is deepening, and the application of surfactants in fermentation has shown great potential and superiority. Especially in the separation and purification of biomass, it has the characteristics of large processing capacity, continuous operation and low activity loss, which makes its application research in the biological downstream engineering become a hot spot. According to the different functions and requirements of surfactants in fermentation production, suitable surfactants can be selected, and new surfactants with green and high performance can be developed continuously. With the development of science and technology, the special structure and function of surfactants will play a greater role in the field of fermentation industry.

In a word, there are many problems in the research of surfactants as fermentation promoters and some of their mechanism are still clear. As talents in the new century, we should devote ourselves to scientific development and benefit mankind.

Surfactants are special structural molecules with hydrophilic and lipophilic groups, so they have a series of application functions, and are widely used in various fields of plastic industry as auxiliaries.

The application of surfactant in the antistatic agent of plastics plastics is a kind of high polymer material with good electrical insulation performance. However, when plastics are used as insulating materials, its surface is very easy to friction and generate static electricity, which will lead to fire, explosion, electric shock and other accidents. Static electricity can be effectively eliminated by adding surfactants to plastics as antistatic agents.
