Abstract
• Revealing the chemistry behind surfactants in everyday commercial goods. • From detergents to ski wax, surfactants impact surprising industries. • Micelles demystified: how surfactants self-assemble in solution. • Insights from 18 key volumes and patents on surfactant innovations. • How surfactants control wetting, foaming, and emulsifying behavior. This review article initiates a series of three, focusing on the chemistry and practical applications of surfactants. These compounds play essential roles in wetting, cleaning, emulsifying, dispersing, and exhibiting anti-foaming and foaming properties across various sectors, including agricultural chemicals, cosmetics, microemulsions, polymer latex systems, biocides, pharmaceuticals, and food products. Through a comprehensive examination of eighteen volumes from the seminal surfactant improvement and development series, the ICI Surface Actives and Detergents, coupled with extensive patent searches, the remarkable diversity in the chemical structures of commercially available surfactants is unveiled. The series focuses on surfactants used in various commercial products, including fabric softeners, detergents, fuel additives, paints, and more. It systematically explores the key characteristics and physical behaviors of surfactants, with particular emphasis on their influence on surface and interfacial phenomena. The review also delves into the natural self-assembly process through which surfactant molecules form micelles.
