Sustainability has come to the fore in the cosmetics and personal care industry. Rising ethical consumerism and the need for resource efficiency are making cosmetic companies – small, independent firms to global giants – take steps towards sustainable development. Sustainability: How the Cosmetics Industry is Greening Up discusses the growing importance of sustainability in the cosmetics industry, highlighting the various ways organisations can address the economic, environmental and social aspects. How can the cosmetics industry make a difference in terms of ingredients, formulations, packaging, CSR, operations, and green marketing? Topics covered include: Environmental and social impacts of cosmetic products Ethical sourcing and biodiversity Renewable energy and waste management Green formulations and ingredients Green marketing issues and consumer behaviour Green standards, certification schemes and indices in the cosmetics industry Industry experts share their experiences on how they are tackling the challenges of sustainability: from raw material procurements, manufacturing, business processes, to distribution and marketing to consumers. The book concludes with some future growth projections; what are some of the shortcomings in sustainability in the cosmetics industry and what can we expect to see in the future? Sustainability: How the Cosmetics Industry is Greening Up discusses business and technical issues in all areas of sustainable product development, from sourcing ingredients, to formulation, manufacture and packaging. Covering a diverse range of subjects, this book appeals to professionals in many key sectors of the cosmetics and personal care industry; cosmetic chemists, formulation scientists, R&D directors, policy makers, business and marketing executives. It is also of relevance to academic researchers working in cosmetic chemistry and sustainable process development.
Macrocyclic and Supramolecular Chemistry. How Izatt-Christensen Award Winners Shaped the Field
This book commemorates the 25th anniversary of the International Izatt-Christensen Award in Macrocyclic and Supramolecular Chemistry. The award, one of the most prestigious of small awards in chemistry, recognizes excellence in the developing field of macrocyclic and supramolecular chemistry Macrocyclic and Supramolecular Chemistry: How Izatt-Christensen Award Winners Shaped the Field features chapters written by the award recipients who provide unique perspectives on the spectacular growth in these expanding and vibrant fields of chemistry over the past half century, and on the role of these awardees in shaping this growth. During this time there has been an upsurge of interest in the design, synthesis and characterization of increasingly more complex macrocyclic ligands and in the application of this knowledge to understanding molecular recognition processes in host-guest chemistry in ways that were scarcely envisioned decades earlier. In October 2016, Professor Jean-Pierre Sauvage and Sir J. Fraser Stoddart (author for chapter 22 «Contractile and Extensile Molecular Systems: Towards Molecular Muscles» by Jean -Pierre Sauvage, Vincent Duplan, and Frédéric Niess and 20 «Serendipity» by Paul R. McGonigal and J. Fraser Stoddart respectively) were awarded the Nobel Prize in Chemistry alongside fellow Wiley author Bernard Feringa, for the design and synthesis of molecular machines.
Physical Chemistry. How Chemistry Works
Much of chemistry is motivated by asking 'How'? How do I make a primary alcohol? React a Grignard reagent with formaldehyde. Physical chemistry is motivated by asking 'Why'? The Grignard reagent and formaldehyde follow a molecular dance known as a reaction mechanism in which stronger bonds are made at the expense of weaker bonds. If you are interested in asking 'why' and not just 'how', then you need to understand physical chemistry. Physical Chemistry: How Chemistry Works takes a fresh approach to teaching in physical chemistry. This modern textbook is designed to excite and engage undergraduate chemistry students and prepare them for how they will employ physical chemistry in real life. The student-friendly approach and practical, contemporary examples facilitate an understanding of the physical chemical aspects of any system, allowing students of inorganic chemistry, organic chemistry, analytical chemistry and biochemistry to be fluent in the essentials of physical chemistry in order to understand synthesis, intermolecular interactions and materials properties. For students who are deeply interested in the subject of physical chemistry, the textbook facilitates further study by connecting them to the frontiers of research. Provides students with the physical and mathematical machinery to understand the physical chemical aspects of any system. Integrates regular examples drawn from the literature, from contemporary issues and research, to engage students with relevant and illustrative details. Important topics are introduced and returned to in later chapters: key concepts are reinforced and discussed in more depth as students acquire more tools. Chapters begin with a preview of important concepts and conclude with a summary of important equations. Each chapter includes worked examples and exercises: discussion questions, simple equation manipulation questions, and problem-solving exercises. Accompanied by supplementary online material: worked examples for students and a solutions manual for instructors. Written by an experienced instructor, researcher and author in physical chemistry, with a voice and perspective that is pedagogical and engaging.
Endocrine Disrupters. Hazard Testing and Assessment Methods
Enables researchers to assess the effects of endocrine disrupters as well as comply with new environmental regulations Endocrine disrupters are chemicals—both man-made and natural—that interfere with the body's endocrine system, potentially resulting in adverse developmental, reproductive, neurological, and immune effects. In recent years, a number of regulatory authorities around the world have drafted or enacted legislation that requires the detection and assessment of the effects of endocrine disrupters on both humans and wildlife. In response, this book provides comprehensive, up-to-date information on the latest tested and proven methods used to detect and assess the environmental hazards posed by endocrine-disrupting chemicals. Endocrine Disrupters is divided into chapters covering each major taxon as well as chapters dedicated to hazard assessment and regulation. The book covers testing methods for all the vertebrate groups and several invertebrate phyla, including: Crustaceans and mollusks Insects Fish Amphibians and reptiles Birds and mammals Moreover, the book emphasizes practical, ethical testing methods that combine sensitivity, efficiency, statistical power, and reasonable cost. Each chapter is written by one or more international experts in ecotoxicology, offering readers step-by-step guidance for implementing each method based on the latest research and the authors' firsthand laboratory experience. Furthermore, all the chapters have been subjected to a rigorous peer review and edited in light of the reviewers' comments. References at the end of each chapter guide readers to the literature in the field. Endocrine Disrupters is recommended for scientists who need to test chemicals for possible endocrine-disrupting properties. It is also recommended for regulatory authorities who need to decide whether particular chemicals can be safely marketed.
