Product Design and Engineering: Formulation of Gels and Pastes

Product design and engineering requires changing the product properties without changing the chemical structure of the active substances. This entails developing the appropriate engineering and formulation processes, starting with the required properties of a product, such as particle size, viscosity, stability, elasticity or durability. For instance, by modifying the surface and interfacial properties or product morphology, new and much better product properties can be obtained. Covering the whole value chain – from product requirements and properties via process technologies and equipment to real–world applications – this reference represents a comprehensive overview of the topic. The editors and majority of the authors are members of the European Federation of Chemical Engineering, and they describe here best practice in product design and production, taking in fundamentals, technologies and applications. This volume focusses on the formulation of gels and pastes, a subject with great impact in many different sectors, such as pharmaceutical or food industry, and highlights rheological fundamentals as well as industrial appliacations. For process, pharma and chemical engineers, chemists in industry, and those working in the pharmaceutical, food, cosmetics, dyes and pigments industries an invaluable source of knowledge and field–proven examples.

Ulrich Bröckel studied chemical engineering at the Technical University of Karlsruhe, and gained his doctorate at the Institute of Mechanical Engineering in 1991. After his industrial career at the BASF process engineering department – leading a team responsible for agglomeration and product design of solids – he became Professor at the University of Applied Sciences Trier in 2000. He is a member of APV, DECHEMA, GVC, and is co–chairing the section group "Product Design and Engineering" at the European Federation of Chemical Engineering (EFCE). Professor Bröckel′s work focuses on solids processing and plant design. Willi Meier studied chemistry at the RWTH Aachen, where he gained his PhD in 1992. He is responsible for the international cooperation of the DECHEMA and is coordinating the research activities of the section groups of the EFCE and the European Federation of Biotechnology. In 2013, he was appointed honorary professor at the Technical University of Clausthal. Gerhard Wagner studied chemical engineering at the Technical University of Munich, where he received his PhD. He has since worked as a scale up engineer in the chemical process development department at Hoffmann–La Roche in Basle, Switzerland, where he is currently responsible for the form development R&D department. Dr. Wagner is a member of the SPIN and the section group "Product Design and Engineering" within the EFCE.
