The application of surfactants in leather production has broad prospects, but there is still a certain distance from surfactants to leather additives. How to use surfactants skillfully in leather production requires the combination of surfactant researchers and Leather Technologists, starting from the characteristics and needs of leather processing, to do in-depth and detailed research. However, with the progress of society, environmental protection is more and more advocated and valued by people, and the development of leather industry is bound to be challenged. Therefore, it is very urgent to develop and research new surfactants for leather production.

Generally speaking, the development of alkyl polyglucoside surfactants for leather should be suitable for environmental protection; it can improve the absorption rate of other chemicals to save chemical materials and reduce leather pollution; it can give leather special properties; it can improve leather production process; it can improve product quality and increase economic benefits. Then, in leather industry production, surfactant will play an increasingly important role.

The environmental protection performance of surfactants mainly refers to the toxicity and biodegradability of surfactants and the improvement of absorption rate of surfactants to other chemical materials.

The solubilization of surfactant micelles may play an important role in the washing process, but many facts are not in accordance with this statement. However, the emulsification of surfactants, regardless of the amount of oil, is always very important in the washing process. In order to emulsify smoothly, surfactants with high surface activity must be added to reduce the interfacial tension. In this way, only a small amount of mechanical work (a little stirring) can be emulsified. While reducing the interfacial tension, the interfacial adsorption is accompanied by the formation of a certain interfacial film, which prevents oil beads from coalescing, which is conducive to the stability of the emulsion. The oil particles are also deposited on the solid surface step by step. However, it is obvious that the emulsification and dispersion of the oil is not enough to complete the washing process effectively. The influence of three factors.
