Surfactants in Biopharmaceutical Development addresses the progress, challenges and opportunities for surfactant research specific to pharmaceutical development. It has been widely recognized that surfactants provide protection to therapeutic proteins against interfacial stresses, which is the reason that nearly all therapeutic proteins in development and on the market today contain surfactants. Despite the fact that the very mechanism of protein stabilization by surfactants has not been completely understood, surfactants are universally regarded as critical functional excipients by the industry and by regulators.

This book provides a broad range of important surfactant-related topics as they relate directly to the biopharmaceutical process. The first chapters of the book address fundamental topics, like mechanisms of protein stabilization by surfactants while later chapters contain the latest-state-of-the-art technology and methods to illustrate the practical application to biopharmaceutical development. Finally, the book concludes with forward-looking chapters on control strategies and novel surfactants with a special focus on current regulatory aspects of paramount importance for biopharmaceutical companies and regulators.
