Industrial Product Design of Solids and Liquids (eBook)

Dr. Wilfried Rähse has been Partner of a start-up (ATS License GmbH) for several years and is responsible for the scientific development of formulations and production processes of novel cosmeceuticals. Previously, Dr. Raehse worked at Henkel AG & Co. KGaA as director in the field of process development. The focus of his activities for washing, cleaning and skin care products were product design, the development of innovative processes and products for the future and the downstream processing of enzymes. His ideas and works led to large production facilities, such as the processing of enzymes, the steam drying in a spray tower and the Megaperls®, a washing powder in form of spheres. Dr. Raehse studied at the Technical University of Berlin chemistry and chemical engineering. He completed his PhD under the supervision of Prof. Dr. Dr. H. Koelbel in 1976. After a period as an assistant (1971 to 1977) at the College followed a 30-year industry activity at HENKEL in process development, but also in the production and in the environmental technology. Dr. Raehse has written many articles and a book (2007) on product design. He holds academic lectures and lecture at universities and at conferences about the optimization of products and processes, including chemical and engineering aspects
