  • What is a Surfactant?

    A brief overview and introduction to the science and application of surfactants.

  • Surfactants, Part I: Fundamentals

    Surfactants are important, or even crucial, in a wide variety of phenomena, including wetting, surface tension reduction, micelle formation, solubilization of organic solutes in micelles, emulsificaiion, dispersion formation, adjusting solution rheology, and foaming. The purpose of this article is to outline the important physical behavior of surfactants, primarily in aqueous solution, because this is where most studies have been done.

  • Surfactants, Part II: Applications

    Surfactants are used in many applications, including consumer products, industrial products and processes, and environmental remediation. The total annual value of surfactants is on the order of $6B. As an example of the commercial importance of applications in which surfactants are crucial, the worldwide annual market for detergent or cleaning products, in which surfactants are an important component, is approximately $100B. The two articles on Surfactants on this page are split in “Fundamentals” and "Applications," with this article discussing applied aspects of surfactant behavior. The purpose of this article is to extend the discussion of fundamental surfactant behavior from Part I, to discuss some applications, like detergency and surfactant-based separations, and to describe environmental aspects of surfactants that influence their use in applications.
