Handbook of Odors in Plastic Materials, Third Edition analyzes the reasons behind unwanted odor formation and outlines methods for prevention. This new edition contains a thorough review of the most recent data, achievements and information in this less known but very significant field of polymer modification. The book covers the fundamentals of odor formation and its transport within a material, the relationship between odor and toxicity, and various methods of odor removal and unwanted odor formation. Three chapters are devoted to the analysis of odor-related matters in different polymers, products and methods of processing. Dozens of polymers and product groups are analyzed, and the book ...
Scent and Chemistry Odor impressions have cast a spell over mankind since the dim and distant past. But even today, we are –consciously or subconsciously– guided by our sense of smell and the chemistry behind it. The prominent fragrance chemists Günther Ohloff, Wilhelm Pickenhagen and Philip Kraft convey the scientist, the perfumer, and the interested layman with a vivid and up-to-date picture of the chemistry of odorants and the research in odor perception. In this second thoroughly revised and updated edition they are joined by creative perfumer Fanny Grau, a rising master in this métier, who complements the scientific treatise by a concise introduction to the art of perfumery and its composition techniques. Besides this new chapter on the creative aspects of perfumery, the book details on the molecular basis of olfaction, olfactory characterization of perfumery materials, structure–odor relationships, the chemical synthesis of odorants, and the chemistry of essential oils and odorants from the animal kingdom, backed up by many perfume examples and historical aspects. It will serve as a thorough introductory text for everyone interested in the molecular world of odors.
The Perception of Odors presents concisely and clearly some of the important aspects in the study of olfaction such as perception, human pheromones, and odor pollution. The book consists of 11 detailed chapters. Chapters 1 and 2 serve as the introduction as it outlines the basic principles, historical development, and the anatomy and physiology of olfaction. A chapter on """"Psychophysics"""" is included wherein it covers the history of the measurement of odors and developments in the psychophysics of smell. The following chapters deal mostly with areas of research such as odor masking, deodo ...
The Perception of Odors presents concisely and clearly some of the important aspects in the study of olfaction such as perception, human pheromones, and odor pollution. The book consists of 11 detailed chapters. Chapters 1 and 2 serve as the introduction as it outlines the basic principles, historical development, and the anatomy and physiology of olfaction. A chapter on ""Psychophysics"" is included wherein it covers the history of the measurement of odors and developments in the psychophysics of smell. The following chapters deal mostly with areas of research such as odor masking, deodorization, adaptation, odor mixture, and memory. Chapter 9 tackles the relationship of smell, particularly the perception of odor, to other senses. The last two chapters discuss the possible future areas of research and problems in odor perception. This book is a valuable reference to students and researchers studying sensation and perception.
This book is the long awaited completely revised and extended edition of Gunther Ohloff's standard work "Scent and Fragrances: The Fascination of Odors and Their Chemical Perspectives". The prominent chemists Gunther Ohloff, Wilhelm Pickenhagen, and Philip Kraft convey the scientist, the perfumer, as well as the interested layman with a vivid and up-to-date picture of the state of the art of the chemistry of odorants and the research in odor perception. The book details on the molecular basis of olfaction, olfactory characterization of perfumery materials, structure-odor relationships, the chemical synthesis of odorants, and the chemistry of essential oils and odorants from the animal kingdo...
In a book whose insight and originality have already had a dazzling impact in France, Alain Corbin has put the sense of smell on the historical map. He conjures up the dominion that the combined forces of smells--from the seductress's civet to the ubiquitous excremental odors of city cesspools--exercised over the lives (and deaths) of the French in the eighteenth and nineteenth centuries.
This book, the second volume of the ISEKI-Food book series, discusses the diverse questions raised by odors in the food industry and the closely related Volatile Organic Compounds. Topics range from perception of the issue to implementation of regulations, from prevention of the problems to their possible treatment, through specific case studies and analysis methods illustrating the different measurement technologies.
Bad breath is a common and embarrassing problem that everyone worries about, yet most health professionals still know little about its origins, diagnosis, and treatment. Over the past fifteen years, investigators have studied how bad breath is caused, where the odors originate, and which bacteria and gases are involved. Novel in vitro systems and measurement techniques have been proposed, and clinical studies conducted to compare new and traditional treatments. This illustrated text presents, for the first time, a comprehensive and cohesive science-based approach to bad breath, combining basic research with clinical approaches to diagnosis and treatment. All aspects of the subject are examined thoroughly and critically, including the psychological impact of breath odor and future prospects. The authors draw upon more than thirty years’ combined experience in this field, both in the laboratory and as consultants to thousands of patients in Canada, the US, the UK, and elsewhere.
Several reasons are behind formation of odors in materials, including the following: - Use of other materials than polymer, especially materials required in processing - Use of various process parameters and their severity in degradation of components of formulation - Recycling of polymeric materials - Contact with natural products (food, cosmetics, etc.) - Storage - Migration-evaporation - Storage in the same space - Diffusion-related properties The above reasons are analyzed for different materials to find out the best methods to prevent odor formation. The book also contains information on testing of odor changes, relationship between odor and toxicity, and the selection of raw materials for fog-free products. The first book in this field, the Handbook of Odors in Materials is needed by anyone interested in materials. - The first book of its kind in this field - Analyzes the reasons behind odor formation and provides the best methods to prevent odors in various materials - Contains information on testing of odor changes and the relationship between odor and toxicity
