Publisher's Synopsis
This book is a presentation and extension of surfactant science and also a technical resource for characterizing and formulating surfactants. It goes beyond the standard guidelines of hydrophilic-lipophilic balance (HLB), critical micelle concentration (CMC), Bancroft's rule, Griffin numbers etc. to focus on surfactant phenomena as a dynamic system. It stresses parameters such as hydrophilic-lipophilic difference (HLD, an extension of Sallager's SAD), curves of surface tension related to concentration, surface excess, partition coefficients, and area per surfactant molecule and shows how these can be used not only to quantify but also to create effective surfactant formulations. In explaining how property variables affect formulation results, the book offers numerous original phase diagrams and equations. A valuable feature of the text is that dozens of traditional and original equations are accessible as computer apps, thus helping readers reinforce their understanding and test their own data. Practical details are presented about concrete products, showing what works and does not. The technology in this text pertains to a range of industrial and specialized surfactants, with explicit attention given to cosmetics, cleaning agents, remediation of oil-contamination, paints, coatings, and biosurfactants.
