Interpretive Summary:

Technical Abstract: Surfactants are one of the most widely applied materials by consumers and industry. The application areas for surfactants span from everyday mundane tasks such as cleaning, to highly complex processes involving the formulation of pharmaceuticals, foods, pesticides, lubricants, etc. Even though surfactants have been known and applied for centuries, they continue to be the subject of vigorous research and development effort. This is because of the continued development of new and complex applications, requiring new and improved surfactants, and a deeper understanding of their performance. This chapter provides an overview of the chemical structures and properties of surfactants responsible for their widespread use. It also provides a discussion of some of the numerous functions of surfactants in lubrication. In addition, an in-depth review of two important functions of surfactants in lubrication, solubilization and boundary friction, is given. The boundary friction properties of agriculture-based surfactants are also reviewed.
