The compounding and Synergistic Technology of surfactants in our country is relatively backward, so we should strengthen the research on the basis and application technology in this field. The technology of multi-functional synergism, solubilization, emulsification, dispersion and anti caking should be paid more attention. Compounding technology is also the key to promote the application of special surfactants in leather making. The results show that the emulsification, dispersion and wettability of surfactants can be improved by adding 10-6 grade special surfactants.

In addition, we should also pay attention to the compatibility of surfactants. Non-ionic surfactants have excellent compatibility with other surfactants and can produce good synergistic effect, which should be paid attention to. Most of leather auxiliaries are compounded products of several surfactants, so synergistic compounding technology is a key technology for the application of surfactants in leather making process.

There are many processes and complex processing environment in leather making process. The penetration and combination of surfactant and leather are the main problems in leather making process. The function of surfactant is required to be carried out mildly. Therefore, surfactants are required to have the characteristics of hard water resistance, electrolyte resistance, acid and alkali resistance, which can be used in multiple leather manufacturing processes; different characteristic groups are introduced into surfactants, which can give leather multiple properties at the same time. In addition, in order to give leather some special application properties, such as light resistance, water washing resistance, water resistance, oil resistance, fog resistance, anti-static and so on, it is required to develop additives with special functions. The development of these new products will be conducive to promoting the leather industry to the direction of high performance, high quality and high added value.

Fluorine-containing surfactants have high surface, high heat-resistant stability, high chemical inertness, hydrophobicity and oil repellency, but also non-toxic or very toxic. The surfactant containing silicon not only contains organic groups, but also contains silicon elements. It is resistant to high temperature, weather aging, non-toxic, non corrosive, physiological inert, and has high surface activity. It is an important direction of the development of leather surfactants, which can give leather special properties such as fluorine and silicon. It will also be one of the development trends of leather chemical material industry.

The extensive use of surfactants in leather production has accelerated the scientific and technological progress of leather industry and the development of the industry. Surfactants have played a significant role in improving the process and product quality. At present, anionic and non-ionic surfactants are mainly used in leather making process, while cationic surfactants and amphoteric surfactants of advanced alkylamine salt and quaternary ammonium salt are seldom used. With the development of economy and the improvement of people's living standard, the demand for new leather products will definitely put forward higher requirements for leather auxiliaries. The development of a new generation of surfactants, especially cationic surfactants and amphoteric surfactants suitable for leather making process, is another focus of the development of leather surfactants.
