Cosmetic Science and Technology: Theoretical Principles and Applications covers the fundamental aspects of cosmetic science that are necessary to understand material development, formulation, and the dermatological effects that result from the use of these products. The book fulfills this role by offering a comprehensive view of cosmetic science and technology, including environmental and dermatological concerns. As the cosmetics field quickly applies cutting-edge research to high value commercial products that have a large impact in our lives and on the world's economy, this book is an indispensable source of information that is ideal for experienced researchers and scientists, as well as non-scientists who want to learn more about this topic on an introductory level. - Covers the science, preparation, function, and interaction of cosmetic products with skin - Addresses safety and environmental concerns related to cosmetics and their use - Provides a graphical summary with short introductory explanation for each topic - Relates product type performance to its main components - Describes manufacturing methods of oral care cosmetics and body cosmetics in a systematic manner

Contains current methods of analysis for new formulations of cosmetics, perfumes, creams, and lotions! With contributions from world-renowned experts in the field, Topical Absorption of Dermatological Products summarizes novel treatments for fungal nail infections emerging risk assessment procedures for sunscreen products

One of the greatest challenges facing chemists and chemical educators today is conveying the central importance and relevance of chemistry to students and society at large. The new edition of Chemistry Connections highlights the fundamental role of chemical principles in governing our everyday experiences and observations. Introductory chemistry students and educators as well as laypersons with an inquisitiveness about the world around them will find the book an informative introduction to the context of chemistry in their lives. The book is written in a lively question-and-answer format with presentations in both lay and technical terms. - Two levels of explanations: general, accessible ones highlight the chemical essence of the phenomenon; and technical ones using chemical principles provide more in-depth interpretation - Indexing of questions according to key principles or terms enhances instructional use - Figures and 3-D chemical structures illustrate the chemical concepts presented - References to related World Wide Web sites for further exploration provide inexpensive and convient access to related information - Color plates enhance connections between specific topics

Since publication of the Second Edition in 1989, numerous innovations have occurred that affect the way scientists look at issues in the field of percutaneous absorption. Focusing on recent advances as well as updating and expanding the scope of topics covered in the previous edition, Percutaneous Absorption, Third Edition provides thorough coverage of the skin's role as an important portal of entry for chemicals into the body. Assembles the work of nearly 80 experts-30 more than the Second Edition-into a unified, comprehensive volume that contains the latest ideas and research! Complete with nearly 600 drawings, photographs, equations, and tables and more than 1600 bibliographic citations of pertinent literature, Percutaneous Absorption, Third Edition details the applied biology of percutaneous penetration factors that affect skin permeation, such as age, vehicles, metabolism, hydration of skin, and chemical structure in vivo and in vitro techniques for measuring absorption, examining factors influencing methodology such as animal models, volatility of test compound, multiple dosage, and artificial membranes procedures for use in transdermal delivery, exploring topics such as effects of penetration enhancers on absorption, optimizing absorption, and the topical delivery of drugs to muscle tissue And presents new chapters on mathematical models cutaneous metabolism prediction of percutaneous absorption in vitro absorption methodology dermal decontamination concentration of chemicals in skin transdermal drug delivery mechanisms of absorption safety evaluation of cosmetics absorption of drugs and cosmetic ingredients nail penetration Emphasizes human applications-particularly useful for pharmacists, pharmacologists, dermatologists, cosmetic scientists, biochemists, toxicologists, public health officials, manufacturers of cosmetic and toiletry products, and graduate students in these disciplines! An invaluable reference source for readers who need to keep up with the latest developments in the field, Percutaneous Absorption, Third Edition is also an excellent experimental guide for laboratory personnel.

The first global account of what seismic shift in the age profile of the world's population means for our money, our work, and the quality of our lives in the new millennium. 35 illustrations.
