Polymers continue to show almost amazing versatility. We have always known that polymers could be used for trinkets, toys and dishes. Now, however, we are no longer surprised to encounter these adaptable mate rials in almost every place we look. We find them in our cars, tools, electronic devices, building materials, etc. The use of polymeric mate rials in medicine is also well documented in previous books by one of the Editors (Gebelein) and by others. Likewise, the use of polymeric mate rials in pharmaceutical applications, especially in controlled release systems, is also well established. Nevertheless, the use of these ubiquitous chemicals is far less ob vious in the field of cosmetics, although modern cosmetic preparations rely heavily on polymers and this trend is certain to increase. This book brings together much of the basic information on polymers in cosmetics and compares this usage with similar applications in pharmaceutical and medical applications. Cosmetics, like medicine and pharmacy, dates back to antiquity. We can find uses of perfumes, balms and ointments in various old books, such as the Bible. For example, the use of ointments and balms is noted more than thirty eight times, and perfumes and related materials are cited at least twenty nine times in the Bible.

Annotation The review focuses on the use of pharmaceutical polymer for controlled drug delivery applications. Examples of pharmaceutical polymers and the principles of controlled drug delivery are outlined and applications of polymers for controlled drug delivery are described. The field of controlled drug delivery is vast therefore this review aims to provide an overview of the applications of pharmaceutical polymers. The review is accompanied by approximately 250 abstracts taken from papers and books in the Rapra Polymer Library database, to facilitate further reading on this subject.

Applications of Polymers in Drug Delivery, Second Edition, provides a comprehensive resource for anyone looking to understand how polymeric materials can be applied to current, new, and emerging drug delivery applications. Polymers play a crucial role in modulating drug delivery and have been fundamental in the successful development of many novel drug delivery systems. This book describes the development of polymeric systems, ranging from conventional dosage forms to the most recent smart systems. Regulatory and intellectual property aspects as well as the clinical applicability of polymeric drug delivery systems are also discussed. The chapters are organized by specific delivery route, offering methodical and detailed coverage throughout. This second edition has been thoroughly revised to include the latest developments in the field. This is an essential book for researchers, scientists, and advanced students, in polymer science, drug delivery, pharmacology/pharmaceuticals, materials science, tissue engineering, nanomedicine, chemistry, and biology. In industry, this book supports scientists, R&D, and other professionals, working on polymers for drug delivery applications. Explains how polymers can be prepared and utilized for all major drug delivery routes Presents the latest advances, including drug targeting, polymeric micelles and polymersomes, and the delivery of biologicals and nucleic acid therapeutics Includes appendices with in-depth information on pharmaceutical properties of polymers and regulatory aspects

This book is based on an international symposium on "Polymers for Cosmetics and Personal Care" held at the 244th National ACS Meeting in Philadelphia on August 22, 2012. The aim of this book is to cover the many facets of polymers used in cosmetics and personal care products and to bring together researchers from industries and academic disciplines from different countries. To our knowledge, this is the first compilation of progress made in the use of polymers in cosmetics and personal industry. This book comprises a collection of papers presented in the symposium as well as several review chapters. Topics in this book have been divided into three sections as follows: Part 1 contains reviews focused on polymers described in this book, polymers used in colored cosmetic products, and organo functional silicones; Part 2 is dedicated to new synthetic methods and strategies; and Part 3 is focused on novel applications of synthetic polymers. In the synthetic portion of the book (Part 2), there are seven chapters. Some chapters discuss specific approaches to controlling molecular architecture and other chapters prepare novel polymeric structures. For example, polymer structures can be controlled using free radical methods in order to prepare unique aqueous rheology modifiers or to create copolymers with unique properties. Additionally, novel materials prepared by combining poly(alphaolefins) with diphenylamine and polymers, novel cationic latex materials, and polymers with unique personal care attributes that are also biodegradable are discussed as well. There are chapters on structure-property relationship as well as on non-penetrating polymerized surfactants. The third part of the book consists of seven chapters, too. It highlights novel applications of materials that may not be typically associated with personal care products. Such polymers include acetylene-based polymers, alkylacrylate cross-polymers, styrene/acrylate copolymers, and silicones. There are also some chapters that discuss other interesting applications of materials by utilizing the enhanced performance they impart to personal care (e.g., ion permeable microcapsules and a polymer adsorption model). This book will be a good resource for those involved in the field of personal care and cosmetics who want to learn of recent developments. Additionally, this book will benefit the reader that would like to become acquainted with the variety of polymeric systems that can be used in personal care products and cosmetics.

Antioxidant Polymers is an exhaustive overview of the recent developments in the field of polymeric materials showing antioxidant properties. This research area has grown rapidly in the last decade because antioxidant polymers have wide industry applications ranging from materials science to biomedical, pharmaceuticals and cosmetics.

In recent years, many animal-derived polymers have emerged as an attractive category of naturally derived polymers because of their advantageous physicochemical, chemical, and biological properties. The important biological properties of these natural polymers derived from animals are biocompatibility and biodegradation. These polymers are generally composed of repeated units of amino acids. Moreover, these polymers can be modified physically and/or chemically to improve their biomaterial properties. Natural Polymers for Pharmaceutical Applications, Volume 3: Animal-Derived Polymers looks at how these polymers can be exploited as pharmaceutical excipients in various pharmaceutical dosage forms, like microparticles, nanoparticles, ophthalmic preparations, gels, implants, etc. The commonly used animal-derived polymers used as pharmaceutical excipients are hyaluronic acid (hyaluronan), albumin, collagen, gelatin, chondroitin, etc.
