The microbiology of cosmetics is also a unique and arcane science and practice that, unlike food or drug microbiology, is not supported by established academic programs or a significant body of publication. Rather it is empirical — learned through experience with principles and practices rarely docu- mented in the literature. The field has few mentors beyond a small fraternity whose secrets are rarely shared. The purpose of this text is to share the unique knowledge of a small group of cosmetic microbiologists and cover all aspects that are critical to providing consumers with microbiologically safe products in a focused dis- cussion that allows immediate application. The first edition of this text was well received, and we have attempted to strengthen this second edition with expanded discussions of manufacturing hygiene and preservation. We have also expanded the regulatory review section to include a global perspective and cover current safety concerns for preservatives consistent with the most recent data. 1453_C000.fm Page 6 Thursday, March 9, 2006 6:08 AM 1453_C000.fm Page 7 Thursday, March 9, 2006 6:08 AM Acknowledgments The Editor thanks the following individuals and institutions whose contri- butions and support made this book possible: Dr. Dan Brannan, my colleague, coauthor and dear friend of many years, who edited the original version of this text and gave me the opportunity to edit this second edition. Contributors to this second edition who took time from their busy sci- entific and technical careers to document and share their unique knowledge and experience. Their efforts will guide readers to the production of cosmet- ics that are microbiologically safe for consumer use. The Procter & Gamble Company for providing decades of practical experience as well as immediate time and resources needed for this effort. Lastly, the U.S. Army's 45th Field Hospital that, decades ago, entrusted to me its clinical microbiology laboratory responsibilities and initiated a career in applied microbiology. 1453_C000.fm Page 8 Thursday, March 9, 2006 6:08 AM 1453_C000.fm Page 9 Thursday, March 9, 2006 6:08 AM Editor Philip A. Geis, Ph.D., is a native Texan who earned bachelor and doctor of philosophy degrees in microbiology from the University of Texas. He is currently a section head with The Procter & Gamble Company (P&G) in Cincinnati, Ohio, and has responsibilities for global microbiology within its Beauty Business Unit. Dr. Geis joined P&G in 1981 as a divisional microbiologist for the devel- opment of preservative systems and disinfectants and the study of house- hold and skin microbial ecologies. His subsequent work focused on micro- biological method development, design and maintenance of sanitary manufacturing systems, and microbial ecology associated with underarm odor, dandruff, toilet soil, and bathroom mildew. Responsible for the tech- nical efforts of multiple operations around the globe, Dr. Geis has acquired unique experience involving diverse regulatory, manufacturing, and product quality realities. His experience and responsibilities with P&G have also included product development and formulation as well as regulatory and environmental affairs. Dr. Geis publishes and lectures on microbiological and environmental subjects, served as an associate editor for the Society for Industrial Microbi- ology News, and represented the technical interests of P&G to professional organizations, regulatory bodies, and scientific societies. He is a member of MENSA, the American Society for Microbiology (ASM), and the Society for Industrial Microbiology (SIM). He is also a trustee of the Ohio Academy of Science and vice president of ASM’s Ohio branch and works to promote science as an ad hoc reviewer for scientific journals and academic programs of ASM, Ohio EPA, and a number of state science standards academic programs. 1453_C000.fm Page 10 Thursday, March 9, 2006 6:08 AM 1453_C000.fm Page 11 Thursday, March 9, 2006 6:08 AM Contributors William A.
