Allured Books

Written by industry experts, and edited by Johann W. Wiechers, PhD, Science and Applications of Skin Delivery Systems is a special delivery system on its own! Each chapter delivers a critical evaluation of a delivery technology open to the cosmetic formulator. Rather than just a showcase of technologies provided by the suppliers of these technologies, this critical evaluation allows the reader to decide what delivery system or delivery technique is most appropriate for his or her application based on scientific evidence.

Bridging the gap between the two extremes of all-science and all-systems books, this reference includes chapters on:

• Measuring skin delivery
• Skin delivery from emulsions
• Encapsulation techniques
• Electrical ways to enhance skin delivery
• Special delivery routes
• Future perspectives

After earning his PhD in skin penetration enhancement from the University of Groningen, The Netherlands, Johann W. Wiechers has spent the past eighteen years establishing himself in the field of cosmetic science. He has worked for companies including Unilever Research and Uniqema as well as become a Visiting Professor at the University of London School of Pharmacy. On July 1, 2007, Wiechers became Technical Advisor for Allured Business Media, serving as advisor for the magazine divisions, as well as the book division. In July 2007 he opened an independent consultancy business in cosmetic science and in September 2007 he became the President of IFSCC.
